Lum Continuous Build Belt Platform 3D Printer

Andreas Bastian developed this very interesting 3d printer with continuous build belt platform. Since it is a movable belt you could, in theory, print continuous or infinitely big objects. Yes, it is a DIY project and it is in development so the builds are rough but the concept is innovative.
The name "Lum" is a version of  the word "loom" as the developer is known for his work in textile-like 3d printed structures.



































Here is Lum printing its own print bed! First part of a print platform belt is made on different 3d printer and then finished on Lum.

Cool Acrylic Painted Centaur Figurine

Guys from 3D Obiecto made this cool "Kentaur Scuplt 1" 3d printed sculpture of a centaur.

Some technical specifications:
  • Zbrush + painting was done by Libor D. Open Art
  • Colorfabb Wood + Black PLA on Mankati fullscale 3D printer
  • 190 x 90mm
  • Acrylic painting + mat lacq
Great work guys!




























Ultimaker Chocolate Syringe Extruder

Here is an Instructable on how to build a DIY chocolate extruder for Ultimaker original. It is based on  20ml syringe with the inner diameter of 20mm. Syringe is covered with aluminum foil, then Kapton tape. The heater is made of NiCr wire coiled on covered syringe and itself covered with Kapton. To get uniform temperature on the syringe a layer is added of aluminum foil and Kapton outside the heater. Thermistor is NTC 100kOhm .

Some people think 3D printing is not a good idea ...

...and they may have some good points. People from Additivism collective focus on general pollution by plastics and critique of consumerist society with more and more stuff being made that severs no purpose ...


























Some interesting bits I found in their presentation:

3D printing + spam + micropayments = tribbles
that you get billed for, as it replicates wildly out of control.

90% of everything is rubbish, and it's all in your spare room – or someone else's spare room, which you're forced to rent through AirBnB.

Linespace Tactile Interface for the Blind with 3D Printing Extruder

Linespace is an ingenious device that uses a 3d printing extruder to produce a large tactile interface for the blind. I love this project! This could be extremely useful for the blind people!

Project description:
Linespace is a tactile display system for blind users. The foundation of our system is a large 140x100cm display area, on which the system creates raised tactile lines with the help of a 3D printer. The foot switch allows users to enter text and issue commands by talking to the computer.

We use Linespace to give blind users access to the type of software packages that normally only sighted people can access, namely the type of software that helps them to make sense of complex data. So far, we have created a simple homefinder program, a spreadsheet program that can read and write Microsoft Excel, two simple games, and a simple programming environment.

One might say that Linespace is an interactive "visualization" system for the blind. The key to achieving this is Linespace large display as it allows displaying a lot of contents at once, where smaller display systems need to update screen contents. The use of lines (instead of the more common Braille dots) helps create visualizations.

The vision behind Linespace is to help blind users interact with and make sense of complex spatial data. It thereby intends to pick up the vision behind of Vannevar Bush's memex, Engelbart Online system, and Xerox PARC's personal computer, by investigating how we can recreate this type of interaction for blind users--how to use computers to help people think better.

In the video you see a user using this system to find homes in Berlin:

SprintRay MoonRay High Resolution UV DLP 3D Printer

SprintRay presented their MoonRay high resolution UV DLP 3D printer. It will be priced at  3499 USD.















Key features:

  • Custom-built projector for 3D printing fine details: MoonRay’s resin requires UV light for proper curing. Other similar 3D printers use commercial projectors, which produce visible light but not pure UV light. The advantages of the custom UV LED projector in MoonRay are in the resolution and curing process. The MoonRay’s UV projector, RayOne, was custom designed with some special qualities:
  • Perfect light spectrum: The resin used for 3D printing cures under light with a 405nm wavelength. The custom-built projector hits the proper wavelength consistently across the build platform, which allows you to get real 100-micron resolution.
  • Runs cool and quiet: Utilizing a UV projector allows the MoonRay to avoid any overheating and makes it much quieter than other 3D printers.
  • Long lifespan: RayOne’s 50,000-hour lifespan means you won’t ever need to replace the bulb.
  • Revolutionary resin tank: the team designed the MoonRay’s resin tank to last, so there’s no more replacing your printer’s resin tank or changing the PDMS layer

rBot 3D Printable CNC Mill with IKEA Work Surface

Michael Reitter developed a homemade 3D printable CNC mill which uses a IKEA MALM table as working surface. Probably the coolest IKEA hack ever.

Someone note in the comments that this is a CNC router. So, what is a different between CNC mill and CNC router?

"A CNC router will usually have a large X and Y range and short Z... A router will typically be able to do soft materials like wood, plastic, and maybe aluminum... But overall, it won't have the most rigid structure (like this one which is 3d printed)

A CNC Mill will have a relatively smaller X and Y with a larger Z than a router... A mill will be able to cut hard materials like steel... And thus will have a very rigid structure so that it can accurately cut those materials."
