Harvey’s Super Huge Printer Now Moves

Harvey's Huge PrinterHarvey has been working on this unreasonably huge 3D Printer for longer than most of the other members have been alive. Well, today marks a momentous occasion, it now moves in all 3 axes!

The printer design is 100% Harvey. It’s all scratch built and went through many on-the-fly revisions during the assembly process. The frame is a 2 foot cube and the print area will be 15 inches cubed. He’ll have to rent a pickup truck to move it!

The Z-axis isn’t leadscrew or belt driven like found on most printers. Here, there’s an elaborate system of kevlar fishing line and pulleys. Today it worked perfectly, raising and lowering the print surface evenly. Now it’s time to set up the firmware and limit switches!

New 3D Printer Project, the iTopie

ITopie RepRap 2.pngToday I started a new 3D Printer build. I found what appears to be a great derivative of the Prusa i3, the iTopie. The i3 looks simple to build but it looks as if it could be a little flimsy with the threaded rod frame.

The original design was made for 16mm MDF. Home Depot only has 1/2 inch so I modified the DXF file a bit to compensate. I also added a handle on the top of the printer frame and make the base a little taller so I could fit an ATX power supply under there.

I used the CNC Router to cut out the parts. The overall cutting time Continue reading
