SLA resin 3D printing is available on request using our Elegoo Saturn 3 Ultra and Elegoo Jupiter printers. Please note that resin printed parts are not as strong as FDM parts and use in structural applications should be avoided.
Resin is a light sensitive liquid that hardens when exposed to UV light. Resin creates a stiff, solid, and high resolution print with a smooth surface finish, making it the best material for miniatures or other non functional prints with a high degree of detail.
We offer prints with water washable resin only and do not use ABS-like or "standard" isopropyl alcohol (IPA) washable resin. When resin is exposed to water it reverts back to an uncured state, thus it is not food safe and should not be used in water applications.
In order to ensure printing is successful, we ask that models are designed to the following requirements:
- Maximum print area size 278 x 156 x 300 mm (length x width x height of Elegoo Jupiter), however models should be considerably smaller than this limit
- Avoid models with large flat surfaces and simple models that would be better suited to the Prusa printers
To request a resin print, please bring separate .stl files for each part to the RPC and do not combine multiple parts into a single file. If you want to send the files electronically you can attach them to an email to engsdc3d@gmail.com but an in person consultation is still required. We will not print any files that are emailed unless you come to the RPC and speak to our staff.
Resin print pricing and timeline
Resin prints are $0.10/gram and they are slightly heavier than prints made with FDM materials. Resin prints are comparable to FDM printers in terms of print time, however they require post-print processing including washing, drying and curing, which significantly increases the manufacturing time.
