Do not allow this machine's host computer to connect to the Internet! This could render the materials we have unusable if it realizes they are expired.

Overview

This is professional 3D printer made by 3D Systems in 2003. It uses a process called Multi-Jet Modeling, which is similar to inkjet, to build a model one layer at a time. It deposits a layer, consisting of both acrylic model material and wax support material, and then cures the model material all at once using an arc lamp. After printing, the wax is melted off to expose the model.

This machine must not be allowed to realized that the date has passed 2007, because it will realize that the model material is expired and refuse to use it (even though it still works). To accomplish this, it is equipped with a dedicated air-gapped laptop, which has the machine's software installed on it. Files may be transferred to this computer using flash drives or other methods that do not involve connecting it to the network.

The model material is extremely hazardous in just about every imaginable way, but the support material is just common paraffin. The UV light from the arc lamp is also hazardous.

Contributors and their expertises

  • Ian O: Generally, I can reverse engineer, diagnose, and repair electronic things, sometimes. Specifically to this machine, I know how to open and close the syringe-heating clamshell things manually (as detailed in this thread), and I have vague ideas on how to diagnose the startup/heating issue. I have no idea how to access the electronics necessary to do that, though. To be able to help effectively, I will need help from people who know how to disassemble the machine. (Also, I think I might be able to bypass the RFID reader that checks for expired materials.)
