BlackBelt 3D printer works with conveyor belt print surface

BlackBelt is a new 3D printer that uses a carbon fiber conveyor belt as build surface. As it prints at an angle it can produce really long objects.  It can make many different objects in series or one big object.
Due to geometry and angle, some objects will need a "starter" object or support to hang on to.
It is also possible to print support-free overhangs!

BlackBelt specifications:

  • Industrial linear guides
  • Build volume of 13″ x 13″ x infinity
  • Adjustable print angles: 45° is the default, but some parts come out better at the lower angles of 15°, 25°, and 34°
  • 1.75 mm filament diameter
  • €9,500 for desktop version, €12,500 for large system with standing supports

This machine looks very interesting, but what gets me suspicious is a lack of video material. There are only a few short videos and no reviews, tests or extensive presentations.

New 3D Printed Airplane Seats Could Make Huge Savings

Autodesk researcher Andreas Bastian used advanced generative design to make a new type of lightweight airplane seat that could make huge savings on fuel and money if applied in future aircraft.
Due to complex geometry, the seat was made on Cronus 3D printer with 5 printheads and then cast in metal.

Project description:
The structure was 56% lighter than the conventional aluminum seats. With 30% calculated to be purely down to the generative design.
Autodesk believes these weight savings could rapidly reduce fuel emissions and thus drastically save costs. Calculating the projected cost savings, the team evaluated the weight savings into fuel savings.
By doing so, the project cites an estimate of $200 million USD in possible reductions over the lifetime of a fleet of 100 aircraft. Additionally, the team calculates fuel emission savings that could compare to removing 80,000 cars off the road for a year.

How to reduce rattling noise on your 3d printer

Tech2C, an Aussi 3d printing youtube, made this video where he shows how to eliminate and reduce the noise, vibration or rattling for his 3d printer.

He uses a HyperCube 3D Printer but his guide is applicable for almost any machine. Used upgrades are rubber feet, foam insulation, stepper motor dampeners or shock absorbers and TMC 2100 stepper drivers with stealthChop mode.

There is a great comment thread under that video with many additional ideas.

ESA 3D Prints Moondust Bricks for Space Colony Construction

Space colonies will be built with 3d printers. We will never see bricklayers and construction workers in space suits.

Technology description:
Bricks have been 3D printed out of simulated moondust using concentrated sunlight. This ESA project took place at the DLR German Aerospace Center facility in Cologne, with a 3D printer table attached to a solar furnace, baking successive 0.1 mm layers of moondust at a temperature of 1000°C. A 20 x 10 x 3 cm brick for building can be completed in around five hours.
DLR Cologne’s solar furnace has two working setups: as a baseline, it uses 147 curved mirror facets to focus either actual sunlight into a high temperature beam, employed to melt together the grains of regolith. But this mode is weather dependent, so a solar simulator was subsequently employed as well – based on an array of xenon lamps more typically found in cinema projectors.
