MendelMax 2.0 review and impressions by ZennmasterM



Great review video of MendelMax 2.0 by ZennmasterM.

MendelMax 2.0 description from RepRap wiki:
The new MendelMax 2 is a complete reinvention of the MendelMax. It makes the MendelMax faster to build, easier to source and even better looking than before.
Design
The MendelMax 2 includes a completely redesigned frame, made from aluminum extrusions and primarily flat plates. These plates can be cut from aluminum, printed, laser cut from plastic, or hand cut with a scroll saw or a coping saw (making this arguably the most accessible DIY reprap ever). A hand cut MendelMax 2 will virtually function identically to a custom machined one. There is no longer a reason to see your hand built machine as merely a means to an end.
Triangles are a smart choice for the gantry, both functionally and aesthetically. From a design standpoint, I wanted the MendelMax to still be visibly a Mendel descendent, while not letting the shape get in the way of improvements. By switching to a right-triangle design, the MendelMax 2.0 gains ~50mm more z-axis movement (the exact amount will depend on your extruder choice). The new design results in a very open, unobstructed print area.

Improving physical therapy with 3d printing



Developed by Dr. Kee Moon and Jeremiah Cox, the device seeks to better conform to the way the body moved before an accident or injury occurred. Rather than rigidly control the movements of the leg, their device nudges - or kicks - the leg to begin natural physical motion. In the future, the bionic leg will further tie in with the brain to better adapt to former muscle memory, allowing the patient to better achieve their previous and unique way of walking or moving.









Mark One first carbon fiber 3d printer

Carbon fiber 3d printing was the technology many people were waiting for. We could finaly get very durable and strong printed objects.




Technical specifications of Mark One:
  • Printing Technology: Fused Filament Fabrication (FFF) / Composite Filament Fabrication (CFF)

  • Connectivity: WiFi, USB, SD Card
  • Price: at 5000 USD range

Mark One website has a following description of their machine:

Brilliant ideas need brilliant materials.
Designed to overcome the strength limitations of other 3D printed materials, the MarkForged Mark One 3D printer is the world’s first 3D printer designed to print composite materials. Now you can print parts, tooling, and fixtures with a higher strength-to-weight ratio than 6061-T6 Aluminum.

Gregory Mark, the President of MarkFoged, also co-owns Aeromation, another carbon high technology company responsible for manufacturing computer controlled race car wings. The wings are typically made out of carbon fiber because of it’s high durability, strength and low weight. They discovered that it is quite a challenging task to manufacture parts out of carbon fiber, because of the time needed and high expense in laying the fiber down piece by piece in the production process. That’s what motivated the development of 3D printer which could simply print the carbon material.

We are waiting for more details and print results!

Mark One is produced by Mark Forged:

http://markforged.com/the-specifications/

Now, after the initial hype, we can say that there are many uncertainties about the technology behind this printer.

  • carbon filament and various carbon fiber technologies have been used in 3d printers before, but as far as I know, no machine has been designed specially for the carbon technology and this would be the first desktop / prosumer printer
  • it is unknown how exactly Mark One prints with carbon fiber: is it a new "special" filament where carbon is mixed in thermoplastics or is it some other technology 
  • carbon fiber (and kevlar) wrapping 3d printed objects to reinforce them was tried before with good results, but it was done by hand: http://diy3dprinting.blogspot.com/2013/06/carbon-and-kevlar-fiber-reinforced-3d.html

Update (18.2.2014.):

here is new, more detailed, video about Mark One:

http://diy3dprinting.blogspot.com/2014/02/mark-one-carbon-fiber-3d-printer-update.html 


Screenshot of Mark One webpage showing that the carbon fiber material is 20 times stiffer then ABS and 5 times stronger

Mark One is multimaterial machine that can print objects with two materials with different combinations of core, shell and structural honeycomb 





















Update:

DIY carbon fiber and fiberglass projects are emerging:

Fuel3d high resolution 3d camera scanner

Technology of 3d scanners is exploding together with the developments in 3d printing machines. Fuel3d is one of more high-end scanner that is much expected to reach the market.

They released the final design of production unit:































Here is the video presentation of Fuel3d and usage cases:




Here is what company claims are main advantages of Fuel3d against competitor technologies:
  • Turntable: The most basic and lowest cost 3D scanning systems use laser point or line projection onto an object positioned and rotated on a turntable. Prices range from a few hundred dollars up to low thousands. As a handheld solution, Fuel3D holds a significant flexibility advantage over these systems, as they are fixed position and the object being scanned is limited by turntable size.
  • Sweeping laser line: To enable scanning of larger objects, scanners are available that project a laser line, which sweeps across a stationary subject. With a few exceptions, prices for these technologies are typically in the $20,000 – $50,000 range. Fuel3D has a very strong price advantage over all these systems, with the added benefit of handheld flexibility and color capture.
  • Hand-held: 3D scanning systems have been developed to enable maximum scan flexibility for working around objects of almost any shape and size. Prices of hand-held solutions are now as low as $15,000 – $30,000. In addition to Fuel3D being much less expensive, we are not aware of any of these handheld systems that collect color data in addition to 3D geometry.
  • Microsoft Kinect: Some low-cost handheld scanning solutions are being developed using the Microsoft Kinect platform. These systems are typically quite low-resolution resolution, so while they are good for capturing environments, they do not have the data precision or resolution for detailed object capture like Fuel3D.












Claiming things for marketing is usual, but, as always, more real-life thir party testing is needed.


The Fuel3D scanner is priced from 1,250 USD without shipping costs or taxes. Estimated shipping start is in September of 2014.

Adobe is getting in 3d printing with Photoshop CC 14.2 update

Adobe is joining the ranks of corporations that got into 3d printing field. Photoshop cc update 14.2 bringe many features for 3d model print preparation and support for several 3d printers.
Support for directly printing from Photoshop CC to 3D Systems Cube, MakerBot Replicator 2, MakerBot Replicator 2x and Zcorp Full Color is built in, as is the ability to export an STL file.
It can work with several 3d print object properties, such as:
  • Printer Volume – This will show the measurement that the model is shown in (the numbers marked in Blue are shown in the chosen measurement).
  • Detail Level – Minimum size of features that can be printed.
  • Show Printer Volume Overlay – This is the cage around the model, the cage is generated and shows the maximum capacity of the print chamber in the 3D printer
  • Printer Volume – The size of the print chamber in the measurements that have been specified above.
  • Scene Volume – This is the size of the physical cage around the model inside Photoshop CC, this can be modified using the numbers, or a fast way to scale the model to the cage is it click the button marked “Scale to print volume”.
  • Surface Details – Photoshop CC will use the Bumps, normal maps and opacity to enhance the final detail.
  • Support Structures – Photoshop CC will generate the supports and raft for the output preview.
For Photoshop CC to be able to print the model, it will automate the following tasks for you, i.e :-
  • Wall Thickness – The model is hollow, the walls will need to be adjusted to make sure the minimum wall thickness is achieved, in accordance to the selected printer specification.
  • Repair the model – The Model may not be, what’s know as “Water tight”, which means it may have holes in it, or normals that are the wrong way around (there are other elements here as well), that will cause the print to not properly.
  • Create scaffolding – The elements that we explained earlier that are ‘floating’ need to be supported during the print.

Short introduction video:



More detailed video with demonstration of new 3d printing features:




Opinions on this move differ from person to person. Some say that Adobe should focus more on their core business and Photoshop CC is just not the most suitable choice for this role and can not replace specialized 3d printing CAD / CAM tools with long development. The future will show how Adobe and Photoshop will fit into the high-end industry where they want to be and how the hobbyist and DIYers will use it.

Here is another video review od Psdtuts+:




Update (8.8.2014):

Adobe released new 3d printing functions for Photoshop CC, they include:
  • Support for the MakerBot Replicator 5th Generation desktop printer and DMM.com (Japan) 3D print service
  • Support for additional 3D file formats including VRML, U3D, PLY, and IGES
  • Streamlined 3D painting experience
  • Ability to easily combine multiple print jobs into a single print bed
  • 3D printing workflow improvements

Using Open SCAD with external advanced text editors Sublime Text, Notepad ++, Textmate and other

If you are using OpenSCAD and you are limited by its simple code editor, you can use it with advanced text editors like Sublime Text or Textmate to code in. They offer many advanced options like syntax coloring, automation of many manual operations etc.

You can use OpenSCAD with almost any external text editor, here is the short explanation:
OpenScad is able to check for changes of files and automatically recompile if a file change occurs. To use this feature enable "Design->Automatic Reload and Compile"
Once the feature is activated, just load the scad file within OpenSCAD as usual ("File->Open..").
After that, open the scad file in your favorite editor too. Edit and work on the scad file within the external editor. Whenever the file is saved to disk (from within the external editor), OpenSCAD will recognize the file change and automatically recompiles accordingly.
The internal editor can be hidden by minimizing the frame with the mouse or by selecting "View->Hide editor".
Open SCAD is programmatic CAD that is used most often, but there are many others. Some of them have syntax coloring, and probably some more could be used with external text editors.

How to mount cooling fan on your 3d printers Arduino to prevent overheating by Barnacules

Barnacules has another nice video tutorial about how he mounted active cooling fan on his Robo 3D printer Arduino controller board to prevent overheating. He used 3d printed mounting brackets.


From video description:
You can print these brackets on your Robo3D with heated bed off to prevent a crash and have your printer fix itself! You don't really need a 2nd 3D printer :P
Get Fan Bracket @ http://www.thingiverse.com/thing:166045 
Today while printing on my Robo 3D I ran into a problem where after 30 minutes it would just shut down and stop printing, after this happened 3 - 4 times in a row I flipped the printer over and felt the ramp board and it was on fire! I checked the forums and talked to some friends and they said that the ramps heat up really bad and can shut down if you run the heated bed at high temps while printing for prolonged time (known issue). The solution is to add some active cooling in the form of a fan to the Arduino board that drives the Robo 3D.

I used my Ultimaker 3D printer to print out a few brackets from Thingiverse.com to mount an 80mm fan to the bottom since I had clearance with the new feet I printed that raised the printer up for the Smart LCD Controller I recently installed (check that video out). The results were epic and in this video I will show you the entire process end to end to fix this problem once and for all.
The brackets were printed w/ following CURA settings on Ultimaker v1
White PLA material
0.2mm layer height
0.4mm nozzle
70c Bed
210c Hot End
100mm/sec
Cooling fan 100%
Total printing time approx 50 minutes...

Update on RepRap Wally - video of big objects printing

Nicholas posted new Wally video:


From video description:
It is about time to provide proof of Wally printing a large object. If you look closely you can see the bed going up and down to adjust for the bed level. It took about 7 hours to print the vase. It is 100mm x 100mm x 145mm. I used a .4mm nozzle and did .2mm tall layers. I used default slic3r speeds. I have gone as much as 4 time faster while I was watching but for an unattended print like this I wasn't as adventurous. I suspect that I can go about 2 times as fast before surface quality suffers.

Matsuura Lumex Avance 25 hybrid metal laser sintering and high precision milling machine

This is not your Prusa Mendel. This is the Godzilla of advanced industrial 3d printers, a hybrid metal laser sintering and high precision milling machine.
It can produce highly precise medical and dental implants and high end custom aerospace industry parts. The structures can have intricate internal structure that can decrease weight, improve cooling or add advanced structural properties.
Lumex Avance can also print complex molds and casts with integrated cooling for high cycle injection molding.
Typically, milling produces debris, or chips, of removed material that vary in size. However, the LUMEX machine utilizes dry cutting, meaning no coolant is used. For this reason, the cutters are very small and the machining metal removal is a fine powder. Thus, the porosity is theoretically equal to the particle size of the powder and gets incorporated into the powder mix. Usually, no removal of milling chips is needed.

Machines like this are the future of manufacturing which is already here, just not evenly distributed.







Technical specifications:













Matsuura will go to north American market with their  hybrid 3d printer. They plan to sell ten machines in 2014 which cost 800,000 - 1,000,000 USD per piece. This reminds me of the time in early history of computing when IBM executives claimed that the world needs only 8 computers.

Wicked MAD 3d printed organic collars and bracelets by MadLab

I REALLY love this designs by MadLab. It is like something from a SF movie. Kudos to the designers!






























Here is the video about design process and technology:



Reverberating Across the Divide reconnects digital and physical contexts through a custom chronomorphologic modeling environment. The modeling interface uses a three phase workflow (3D scanning, 3D modeling, and 3D printing) to enable a designer to craft intricate digital geometries around pre-existing physical contexts.
Chronomorphology –– like its nineteenth-century counterpart chronophotography –– is a composite recording of an object’s movement. Instead of a photograph, however, the recording medium here is a full three-dimensional model of the object — a virtual creature simulated within a digital environment. This virtual creature exists as a 3D printable module; it is constructed as a closed mesh, with a spring skeleton that prevents self-intersections. The composite, chronomorphologic model (of the virtual creature over time) retains these printable properties at each time-step. Therefore, no matter how intricate or complex, the digital geometry will always be exported as a valid, 3D printable mesh.

The chronomorphologic modeling environment facilitates the rapid generation of baroque and expressive spatial forms that both respond and expand on existing physical contexts. By mediating 3D scanning and 3D printing through the modeling environment, the designer has a streamlined workflow for oscillating between virtual and analog environments. This ease between digital design and physical production provides a framework for rapidly exploring how subtle changes in the virtual environment, physical environment, or designer’s gestures can create dynamic variation in the formal, material, and spatial qualities of a generated design.

3D printing rubber inflatable complex structures (the flower blossom was probably not the first)

At Victoria University of Wellington's School of Design, Richard Clarkson 3D printed these complex flower shaped objects from a soft rubber multimaterials that are inflatable and adapt to air pressure.




Recent advances in 3D printing now allow the simultaneous deposition of different build materials in a single print. In a similar way to nature, materials can be distributed seamlessly within objects for structural and functional advantage. “Blossom” explores the blending of two materials with varying physical properties transitioning from flexible to rigid. The variation offers an opportunity to generate complex forms and dynamic structures that are impossible to make by any other means. The research into applications of these Digital Materials™ has resulted in what is believed to be the world’s first inflatable 3D print. Forcing air into the cavities of the print causes it to ‘bloom’ and thereby reveal the complexity of its physical structure.

If you ask me, it looks somewhat creepy when its magnified and moving ...


























I wanted to check the claim that it was the worlds first air inflatable 3d printed rubber object. On youtube I found this video published in September of 2013 that shows something that looks like layer 3d printed rubber inflatable object that has a system of chambers to manipulate the shape and vibration pattern by applying pressure.

What software should I use when starting 3d design and modelling for desktop manufacturing?

There are many options and variables when choosing the 3d design software that suits your needs when you get into 3d printing.
Here is a useful decision tree chart that will simplify the decision based on price, platform and your personal preferences:

MTM Multifab multitool desktop manufacturing machine

MTM Multifab is truly multifunctional desktop manufacturing machine that was very innovative and ground breaking in the field of  DIY 3d printing when it was developed. Ultimaker, very well known and powerful 3d printer,  is based on this machine.
Multifab has several replaceable tool head options:

  • MACHINING SPINDLE, A high-speed (20K RPM) spindle supports light subtractive machining. The spindle can be constructed entirely from off-the-shelf compoents.
  • VINYL CUTTER, A razor blade tool which allows 2D cutting of sheet material. Some applications are flexible circuit boards, stickers, silkscreen masks, and more.
  • REPEATING PIPETTER, This fluid dispensing toolhead was created in collaboration with MIT's Innovations in International Health program, and has uses in automated biology research and disease diagnostics fabrication.
  • PLOTTER HEAD, A pen attached to the multifab can allow easy labeling of objects, caligraphy, etc...
  • 5 AXIS TRUNNION, This attachment permits 5-axis machining of components on the Multifab. Potential applications include variabl-helix screws, impellers, and 5-sided machining operations.
  • PLASTIC EXTRUDER, Based on the Rep-Rap project, this extrusion head will enable additive manufacturing in plastics such as ABS.

Here are some videos of Multifab in action writing and pipettering:





Demonstration of the MTM Multifab fitted with an auto-pipetting toolhead. The toolhead was designed with Amber Houghstow and Jose Gomez-Marquez of the MIT Innovations in International Health program, with the goal of automating production of XoutTB diagnostic assays. Perhaps it can also find a use in the DIY Bio community.
The MTM Multifab is part of the MIT Center for Bits and Atoms Machines That Make project.

Here is overview of Multifabs components, tools and development status:


http://mtm.cba.mit.edu/fabinabox/devmultifab.html

The instructions, plans and BOMs should be available for anyone who wants to build it, but all the files and documents links I tried on the site were broken. I hope it will be repaired soon, the public could benefit greatly with this machine.

Fab-in-a-Box


The Multifab is core machine of FAB in a Box framework system that should provide full digital fabrication environment that user could make at their home from simple parts. It contains:

Infrastructure. All of the key services which allow Fab-in-a-Box to be a cohesive toolset. These include the network, the box itself, power distribution, etc. It consist of the:

  1. VIRTUAL MACHINE ENVIRONMENT, The flexible Fab-in-a-Box machine control and interface environment.  
  2. THE NETWORK: FABNET, An RS485-based network is the nervous system of the toolset, which connects the "brain" - a laptop running control software - to the tools and sensors comprising Fab-in-a-Box. 
  3. THE SUITCASE, The suitcase is the heart of the matter. It is what contains the entire fab in a box project.

Multifab. A computer-controlled multipurpose fabrication tool. Work includes integration into the box, the xyz motion stage, and multiple toolheads to perform various fabrication tasks. Multifab has many subsystems, components and parts:

  1. XYZ GANTRY, The key component of the multifab tool is a high-speed and rigid xyz gantry capable of accomodating a wide range of fabrication processes.  
  2. 3-AXIS MOTION CONTROL, The multifab gantry is controlled by a networked controller board capable of controlling three stepper motor drivers simultaneously.  
  3. H-BRIDGE, This module is able to control the average voltage across a load, such as the spindle's DC motor, using a technique called Pulse Width Modulation (PWM).  
  4. RC SERVO CONTROLLER, RC servos, typically found in radio controlled airplane models, use feedback to control the position of their output shaft. This controller can set the position of up to 8 servos, and is used in the auto-pipetter toolhead.  
  5. MACHINING SPINDLE, A high-speed (20K RPM) spindle supports light subtractive machining. The spindle can be constructed entirely from off-the-shelf compoents.  
  6. VINYL CUTTER, A razorblade tool which allows 2D cutting of sheet material. Some applications are flexible circuit boards, stickers, silkscreen masks, and more.  
  7. REPEATING PIPETTER, This fluid dispensing toolhead was created in collaboration with MIT's Innovations in International Health program, and has uses in automated biology research and disease diagnostics fabrication.
  8. PLOTTER HEAD, A pen attached to the multifab can allow easy labeling of objects, caligraphy, etc... 
  9. 5 AXIS TRUNNION, This attachment permits 5-axis machining of components on the Multifab. Potential applications include variabl-helix screws, impellers, and 5-sided machining operations. 
  10. 1-AXIS MOTION CONTROL, Additional axes can easily be simultaneously controlled by adding them onto the network. The disadvantage as compared to a multiple-axis controller is increased network load.
  11. PLASTIC EXTRUDER, Based on the Rep-Rap project, this extrusion head will enable additive manufacturing in plastics such as ABS.
  12. JOG DIAL, The multifab can be positioned by hand using a networked jog dial. This interface can also provide more complex control of parameters typically adjusted on the computer such as feed rate.

Other Fab. All other tools needed to make something. Examples are the soldering iron, hand tools, and programming interfaces.

  1. SOLDERING IRON, A soldering iron with temperature adjustment over the network.
  2. AUTO BINS, Parts bins which light up to indicate where a needed component is located. This could be part of a computer-assisted-stuffing project.
  3. FUME EXTRACTOR, A fume extractor with a ring of LED lights around its intake.
  4. IN-CIRCUIT PROGRAMMER, A network-attached microprocessor programmer.
  5. NETWORK BOOTLOADER, A bootloader which fetches programs over Fabnet.

Measurement. Networked instrumentation such as a multimeter and oscilloscope. This is one area which will hopefully expand greatly on the road.

  1. MULTIMETER, A multimeter which displays and records its readings on the Fab-in-a-Box laptop.
  2. OSCILLOSCOPE, An oscilloscope which displays and records its readings on the Fab-in-a-Box laptop.

Autodoc. Everything related to making it possible to document a project "without thought".


  1. EYE-FI CAMERA, A camera which wirelessly tranfers its time-stamped images to the Fab-in-a-Box auto-documentation software.
  2. RFID READER, Keeping track of which hand tools were used, and when, is made easy with an RFID reader.


Some of the components were never developed, and most of the building related file links can not be opened. Probably all the files are somewhere on the internet, it would be terrible if they get lost forever. I REALLY hope someone publishes them as open source soon.

Making Machines that Make talk by Nadya Peek

Must-watch video if you are interested into DIY, desktop manufacturing machines, hacking, making and generally awesome stuff!

Nadya Peek speaks about the process and basics of making machines that make, technology, digital fabrication economics, MIT modern high-end CNC machines and their limitations, how g-code is very stupid  and how biologists buy expensive machines that are easy and cheap to DIY ...
She also talks and shows many interesting machines that you can make yourself like liquid transfer and auto pipetting machines...



From video description:
Making a new control system for a machine is often a slow and tedious task. Maybe you already have a 3 axis stage, and you already know how to move it around. But what if you want to add a camera and use it for position feedback? You'd have to redesign the whole hardware layer.
I'll talk about some ways I've built modularity into control systems for machines so that you can quickly iterate on different kinds of machine systems without getting stuck in hardware land forever. This includes connecting synchronized nodes across a network and importing legacy nodes for things like, say, an old pressure box you found in the trash and has rs232 in.
Down with gcode! Long live machine control.

I found one of her presentations which loosely follows the theme of the talk in PDF format:

http://cba.mit.edu/events/13.03.scifab/Peek.pdf

She also spoke about some high end CNC machines being monitored by gyroscope, sensors and GPS so they can not be moved without authorization to prevent them begin exported to blacklisted countries. Here you can see the perfect example of that crazy security policy: http://boingboing.net/2014/01/06/high-end-cnc-machines-cant-b.html

axCut DIY laser cutter

Damian Axford is developing new open source DIY laser cutter. axCut is influenced by nopheads Mendel90, BuildLog 2.x and Lasersaur. It is still under development but it looks very promising. I'll follow the project since I'm getting more and more interested in laser cutters.



axCut project requirements:
  • 40W CO2 laser (with space to upgrade to at least 80W - i.e accommodate a 1000mm tube with water cooling)
  • Bed size to accommodate A1 stock - design files use 850mm x 600mm with 30mm margin all round
  • Fully enclosed
  • Allow for pass-through (i.e. very long items)
  • Allow for high/tall items and "autofocus" via motorised bed (150+mm travel)
  • Have unobscured front access for loading/unloading parts
  • Bench-top design (may integrate a bench at a later date)
  • Side connections for extraction and cabling (i.e. power, usb)
  • Investigate using reprap s/w stack vs Mach3 - I'd really like to leverage as much as possible from the reprap community (e.g. modified sprinter firmware)
  • Budget target of £1500 (max £2000)

Paperduino - Arduino printed on paper with conductive ink

It is not 3d printing but it is a sort of DIY additive manufacturing. Arduino Pro Mini board was made by using a pen plotter and the Electroninks Circuit Scribe roller-ball pen with highly conductive ink to draw a circuit on a sheet of paper. Electronic components are then mounted on it with glue or sticky tape. And it works!



This method for conductive ink printed circuits could be easily adapted for 3d printers. There are also several methods to produce DIY conductive ink with various material mixtures.
Also you shoudl keep in mind that this is made from paper, so if you put too much voltage in, it could catch fire. Stay safe.

Detailed instructions and all the files can be found here:

http://www.instructables.com/id/Paperduino-20-with-Circuit-Scribe/?ALLSTEPS

























Conductive ink on paper sheet electronic circuit production is technology that is finding more and more practical applications, you can see interesting sensor here:

http://diy3dprinting.blogspot.com/2013/10/off-topic-sensprout-2d-printed.html

Here is one of the many methods to produce homemade conductive ink. This one is easy and cheap, maybe not the most suitable for this type of project. It is made from copper particles suspended in gum arabic water solution.

PCB etching with UV laser on Pegasus Touch SLA 3d printer

The Pegasus Touch team found out another use for their printer. UV laser can etch UV sensible PCB boards to make surface for electronic components. Pegasus Touch will get software upgrade to implement this function.
This could become standard feature in all UV laser equipped stereolitographic 3d printers, their software and drivers need some simple upgrades which will hopefully be provided by manufacturers or third parties.



One commentator on Hackaday noted:
Neat, but useful?
Currently I print my board on two transparencies, then aligning them on the UV-sensitized board, then placing whole thing under a UV light source. Two minutes of work followed by five minutes of wait?
This new method would have me remove the resin tank, align and mount the PCB to the build platform (double sided tape?), convert my gerbers to a jpg/bmp, then finally print to the 3D printer?
IF it’s saving time/money, it doesn’t appear that significant. Maybe if mounting and aligning the PCB was very quick and easy? Although I’m imagining a frustrating process involving double-side tape and wasted copper clad trying to correct the alignment.

So, this function could be useful in some situations and usage scenarios, but you will get the PCB etching job done faster if you are experienced user. This upgrade is simple software addon, so it is nice to have some extra features in a single machine.
