Toorcamp: Type A Machines

Type A Machines designs and builds 3D printers in San Francisco. [Miloh], one of the founders, brought two of their flagship Series 1 printers to Toorcamp. He printed out a variety of models including water tight cups and quadcopter arms.

The RepRap Arduino MEGA Pololu Shield (RAMPS) is used to drive the stepper motors for each axis, as well as the extruder. This is attached to an Arduino MEGA running the Marlin RepRap firmware. Type A Machines ships the printer with Polylactic Acid (PLA) filament, which is biodegradable.

On software side, you start with a 3D model in STL format. This can be exported from 3D software such as Google SketchUp or Autodesk 123D. You then need a slicer to generate G-code and machine control software to command the printer. [Miloh] used Slic3r and Repetier for his workflow, but he also pointed out a good summary of 3D printer workflows.

The Series 1 was launched at the Bay Area Maker Faire this past May. It has a print volume of 1200 mL, which is the largest print volume of any desktop printer around. The Series 1 brings another option into the low-cost 3D printer market.

Toorcamp: Hackerbot Labs’ Giant FAA Approved Laser

This is a big laser.

[3ric] from Hackerbot Labs gave me a run down of their BattleYurt laser installation at Toorcamp. It’s built with twenty-four 1 Watt lasers taken from a Casio DLP projector. The laser is housed on top of a yurt, which contains the controls and cooling system. It was built with the goal of measuring diffuse reflections of the atmosphere, but it also does the job of looking awesome when fired into the sky. [Read more...]

R2D2 drink dispenser will happily tinkle in your glass

As with Jabba the Hutt we’d like to have our own service droid to serve up a cold one. We’re in luck; it looks like you can make your very own beverage dispensing droid if you don’t mind a little awkward dispensation.

The body started as one of those big protein drink mix containers. After spraying it white and masking off the entire thing with blue painter’s tape, the shapes for the blue designs were cut out and painted. Half of a foam sphere from the hobby shop was used to form the dome.

Liquids are dispensed by the pump system from a Super Soaker motorized water gun. You can see it fill up a beaker with a mysterious blue liquid in the video after the break. It’s a long way from challenging the Bar2D2, but it’s also something a mere mortal can build
