Resin Printing
Design Processes
3D printing by curing liquid resin with light, for fine detail and smooth surfaces.
In practice
Resin printing — SLA, DLP and MSLA are the main flavours — builds parts by selectively hardening a vat of photopolymer with a laser or projected UV image, layer by layer. It gives the finest detail and smoothest finish of any desktop process, at the cost of messy handling, brittle materials and parts that need washing and post-curing. It is the standard for appearance models, dental and jewellery work.
Questions
What is Resin Printing?
Resin printing is an additive process that solidifies liquid photopolymer with light to produce highly detailed parts with smooth surfaces.
Why do you use Resin Printing?
When the surface has to look finished or the detail has to be crisp, nothing else on a desk comes close.
How do you use/apply Resin Printing?
Orient to minimise supports on visible faces, hollow large volumes with drain holes, print, wash in solvent, remove supports, and post-cure under UV.
When do you use Resin Printing?
For appearance models, small precise parts, masters for casting and anything where finish matters more than toughness.
Who uses Resin Printing?
Industrial designers, model makers, jewellers and dental technicians.
