3D Printers

From Idea Shop Wiki

The Idea Shop offers five different types of 3D printers for users to choose from, with variations in material, price point, durability, printing speed, and overall finish. Use this guide to choose which printer will best suit your project.


Processing 3D Files

In order to be able to print anything in our 3D printers, your file MUST be in .stl format1. The STL format describes only the surface geometry of the object instead of the object as a whole. Once done, open the file in the Autodesk Netfabb software to repair the file.

We will only process STLs which have:
1 shell per continuous part
0 border edges
0 invalid orientations
0 holes

See Fixing STLs for more information.

Even if Netfabb reports no invalid orientations, if we see red triangles in repair mode there is a problem with your model. Print at your own risk.


Once your STL is ready to go and free of errors, ask an employee to assist you in setting up your print bed and sending your job to the 3D printing queue.

1 Color files for the zPrinter 450 can also be .vrml files.

Monoprice Mini Select v2

Monoprice Mini

The Monoprice Mini Select v2, developed by Monoprice, is a (FDM) 3D printer. We have two Monoprice Minis here in the shop. These printers are free for users! However, the use of these printers is not supported by Idea Shop staff - aka, you're on your own!

Students are responsible for all aspects of using the machine, as laid out on this page. Please make an effort to follow the suggested settings, and try to keep your prints as short as possible. The printer is only available for use during normal operating hours, as it presents a fire hazard, therefore all prints must be executed before the end of the day.

This printer is much more simple than others available in the lab, and may not be able to handle complex geometry. If complex geometry is needed, consider using a different printer in the lab.

General Stats:
Material : Polylactic Acid (PLA)
Maximum Part Size : 120mm x 120mm x 120mm (4.7in x 4.7in x 4.7in)
Layer Thickness : Customizable
Resolution : 100 microns (0.1 mm)
Price : Free!



Stereolithography (SLA)

Form2
