Stereolithography is known for producing extreme detail, with layers down to four times finer than a human hair.

Inventadore offers standard Clear photopolymer resin for general prototyping. Photopolymer resin produce accurate and robust physical models. Inventadore also offers functional resins with varying mechanical properties such as Castable and Flexible.
A Castable Resin gives jewellers and engineers an inexpensive way to produce metal parts.

A Flexible Resin is great for simulating different textures. 

Let’s compare how the SLA parts stand up against a FDM parts.

Plastic extrusion, or fused deposition modelling (FDM), is the most common 3d printer technology; FDM printers melt plastic and use an extruder to print each layer with molten plastic. The vast majority of plastic extrusion machines lack the finish and resolution for professional-grade output. SLA can outperform the print quality of even high-end FDM machines. In our photopolymer-based process, a high precision system directs a laser across a tray of liquid resin and causes a thin layer to solidify. Until now, a professional SLA printer has been far out of reach for the individual designer.

The stereolithography print comes out nice and smooth, but we can see and feel the ridges on the cup printed with FDM filament. 

When we break this sample piece, you can see that filament parts quickly snap along the layer lines. The SLA process creates a chemical bond, so SLA prints takes much more force.

Stereolithography has become an excellent economic choice for rapid prototyping appearance models. A wide variety of industries have embraced SLA, including medical, automotive, entertainment, aerospace, and consumer products.
