3D SLA Printing

3D SLA Printing with the Formlabs 2 #

Form2

Due to the intricacies of the printing process these machines are currently only operable by a member of staff. You can submit a job to our Bureau Service. If your project requires this functionality - please approach a lab technician when you have made yourself familiar with the resources below and prepared one 3D print with PreForm

3D Model preparation #

Basics #

  1. Prepare your model with the PreForm software. Read about model orientation here: model orientation best practices for SLA printing

  2. Inspecting layers with the Slicer tool in PreForm

  3. Preventing suction cups in PreForm

  4. Reducing unsupported minima in PreForm

Solid structures #

Solid structures will waste a lot of resin and make the print more expensive. Formlabs recommends hollowing out your model and then using PreForm to create internal supports.

Most printed models will be strong enough when printed hollow, however, you could research the option to fill it with a material, such as epoxy.

Preparing for printing #

  • Approach a HatchLabs technician to discuss your print. The member of staff will ask several questions before uploading your file.
    • Please bring your computer to show the technicians your PreForm setup with the model orientated and discuss any printing errors.

Washing #

Note this can only be carried out by HatchLabs technicians!

Most models have to be cleaned in two baths of IPA for around 10 minutes each. For smaller 3D prints, this can be shorter: SLA basic finishing steps

Curing #

  • Always double check the material cure time recommendation: cure time information
  • See here for post-curing prints best practices including how to cure large, long, thick, thin, or densely-supported parts
