One of the coolest things I’ve seen to print so far is this Platform Jack on Thingiverse. The platform jack, also known as a scissor lift, or jack stand, contains many moving parts, but it incredibly prints as one part, fully assembled, with no supports required!
Here’s a video (not my own) that demonstrates how the platform jack works:
My Solidoodle Press 3D printer is not as well equipped as more expensive printers, so many objects are very challenging to print especially if precision is a key concern. ABS, the type of plastic filament used by the Press, also tends to wrap and crack for many types of prints. However, with some persistence and careful research, I managed to print a working platform jack, using ABS, on my Press! Read on for my results, and the settings I used in the Simplify3D software.
My first attempt was not successful. The screw fell apart easily, since it was hallow on the inside with a weak outside shell. My second attempt was 100% solid, but the arms were still too brittle, and broke before I even removed the jack from the printer.
Finally, I tweaked more of the print settings, and increased the size of the jack by 10%. After 5 hours, the print was done, and I was ready to inspect it. It looked OK on the outside. I removed it from the printer, made sure the individual pieces weren’t sticking together, and then turned the screw. It worked! The jack extended. It opened and closed several times without any pieces breaking or other difficulties. I had finally printed the platform jack successfully!
I used the following settings in Simplify3D.
- Scale: 110%
- Infill Percentage: 100%
- Extrusion Multiplier: 0.85
- First Layer Width: 200%
- Primary Layer Height: 0.3mm
- Temperature: 240 degrees Celsius
- Horizontal size compensation: -0.07mm (as recommended by 3D Printing Nerd on YouTube)
You can download the settings as a FFF file for Simplify3D.
