First Attempts at Aluminum Casting

by on Jul.11, 2014, under Crafts, Meetings, omgwhathaveidone, RepRap

Scott brought a plaster mold to the open house meeting tonight. He used 3D printed PLA parts and used the forge to burn out the PLA plastic and to melt some aluminum cans and some aluminum heat sinks. We ended up cooking the mold a bit too much, it was rather fragile. We could probably burn it out in under 30 minutes for the next attempt. While not perfect, we learned a lot!

Midsouth Makers is getting a dedicated 3D Printer!

by on May.22, 2013, under Arduino, Arduino Projects, News, Projects, Prusa, RepRap, Workshops

If you’ve been following Midsouth Makers you know that we’ve been building. using and tweaking our 3D printers for a while now. Well thanks to a kind donation by LulzBot we now have a dedicated 3D printer at the space for member use! The printer is an AO-101, a MendelMax 1.5 variant.Lulzbot-3D-printer-RT

The AO-101 currently uses 3mm filament and can print in ABS, PLA, Nylon and even Laywoo-D3 wooden filament.  We  have it setup to allow for remote printing on the LAN, using either OctoPrint or Repetier-Server. We recommend Repetier-Server due to it’s stability.

The AO-101 will be using a donated a 1U server as the host computer. Repetier-Server will allow you to load a gcode file and control the printer. We will be exploring webcam functionality for use in monitoring and in generating time-lapse print videos.

We will need the following items to get our new 3D printer setup and functional:

  • Filament- Currently setup for 3mm:
    • ABS
    • PLA
  • Webcam- Logitech C110 or C270 preferred (we’ve already tested and confirmed stability)
  • 120mm silent PC case fan

AO-101 Specifications

  • Build Area – 190mm 200mm 100mm
  • Hot-end – Budaschnozzle 1.2
    • Extrusion temperature range – 180C – 240C
  • Filament- Currently setup for 3mm and can reliably print the following material types:
    • ABS
    • PLA
    • Taulman 618 Nylon
    • Laywoo-D3 Wooden Filament
  • Heated Print Bed (65C-110C)
  • Borosilicate Glass Bed  with PET film on one side for printing with ABS and bare glass on the other side for printing with PLA
  • Integrated Filament Mount for either loose coiled filament or spindles for spooled filament

Current AO-101 Modifications

  • Nozzle Fan for printing in PLA installed but not hooked up
  • RGB LED lighting (white for now)

More information on the new 3D printer can be found in our wiki.

If you’d like to use it, please contact Claudio, Ben, Dan or Cliff- more information will follow. In order to have access to the 3D printer without one of us present you will need to have had verified prior experience with a RepRap 3D printer, or attended an upcoming class on running & troubleshooting 3D printers(TBD) or be able to demonstrate the appropriate knowledge.

Please show our thanks and appreciation to LulzBot and the RepRap community!

Flying 3D Printed Quadcopters

by on May.18, 2013, under Electronics, Projects, Prusa, RepRap

We are slowly and painfully making progress with learning to fly our 3D Printed Mini Quadcopters. Cliff has helped us out with some tweaks & balances. Hopefully some more members will be interested in building their own, and will help add to the swarm.

Building 3D Printed Quadcopters For Fun and Chaos

by on Apr.27, 2013, under Arduino Projects, Electronics, Projects, Prusa, RepRap

Recently Ben, Cliff and Claudio have built Diametric’s Mini Quadcopter. We met a fellow RepRap user- Diametric- at this years Midwest RepRap Festival in Elkhart Indiana. He brought along a 3D printed quadcopter that he designed and built.

The quadcopters are remarkably inexpensive, the design, models and bill of materials can be found on Thingiverse. They are easy to build and easy to get off the ground. We’re still learning how to fly them however. While all three have taken flight, we have had some accidents and damaged the frames on 2 of them, twice. We’re not too worried when that happens, for we can always reprint the frame within about an hour and a half on one of our 3D printers.
