3D Printers

General Information

3D printers are a form of additive manufacture (AM) that allows a user to turn a CAD model into something physical. This is great for rapid prototyping or for physical illustration of designs.
3D printers are one of our most used engineering tools here in the iForge.

We currently have two main types of 3D printer, those which work by extruding hot plastic in layers and gradually building up a model (FFF/FDM) or those which work by selectively curing a photosensitive resin layer by layer to build up a part (SLA). FDM/FFF is what we mainly focus on as it is much easier to take any model and turn it into a physical object, however we can do SLA prints by request based on their merit. If this is something you’re interested in, come in and have a chat to one of our reps!

Getting Started

  1. As with all of our machines and tools a user will have had to do the online training prior to using our facilities for 3D printing.
  2. Export your CAD file as a 3D mesh – we can use the 3MF or STL filetypes (“Save As Mesh” on bodies in Fusion 360).
  3. Bring your files into the iForge on a USB stick. Email submissions cannot be accepted.
  4. Talk to one of our friendly iForge Reps, who will guide you through the slicing process and add your print job to our queue.
  5. Wait for the print to complete! You will receive an email when it is ready to pick up from the iForge.

All of our prints are printed in PLA, currently we don’t offer any other materials however this may change in future. We also put a rough time limit on user prints set at 10 hours, this is to allow everyone fair and equal use of our printing time.

All print jobs are done in the iForge at the 3D Printing Team’s discretion.

We reserve the right to reject any print we deem unsuitable for manufacture using our equipment.
