Belonging to a group of additive manufacturing processes known as vat polymerisation, Stereolithography or SLA is a popular 3D printing technology favoured for its highly efficient printing of extremely smooth surfaces and intricate designs.
SLA 3D printers use a laser to selectively cure layers of high temp resin; layering them on a build plate to create a solid, 3D version of the specified computer-aided design (CAD) model. SLA models offer a smooth high-resolution finish and intricate detailing unrivalled by other 3D printing technologies, however, parts can be brittle, sensitive to sunlight and always require support structures.
What is SLA used for?
Composite Tooling Applications – SLA printers facilitate the production of high detail parts in both large and smaller formats. Even with a slower 3D printer like an SLA machine, composite tooling times can be reduced from weeks to days.
Rapid Prototyping – While SLA parts are brittle and not suitable for use in functional prototyping, SLA technology produces a smooth surface finish and high fine detail resolution ideal for the product development process and visual prototyping. 48-hour turnaround available!
Modelling & Moulding – 3D resin printing is the ideal way to create intricate, high detail models and master moulds for a number of industries and sectors including manufacturing, engineering and product design, and healthcare.
- Layer thicknesses ranging from 0.025mm to 0.1mm
- Accurate to 0.1mm
- Range of different material properties for each application (ie, rigidity, durability etc)
- Build volume of 145mm x 145mm x 175mm
- High detail printing
