How many colors can the Form 2 from FormLabs print at a time?

The Form 2 from FormLabs is designed to print in a single color at a time. This limitation is primarily due to its SLA (Stereolithography) technology, which uses a resin tank filled with a specific photopolymer resin to create parts layer by layer. Each print requires a single type of resin to achieve the desired mechanical properties and surface finish of the printed object.

While users can swap out resins between prints to achieve different colors or material properties, the printer itself operates by using only one resin type during a print job. Multiple materials or colors can be combined when designing the model and then printed separately, but during the actual printing process with the Form 2, it is a single color at a time. This characteristic is typical for many SLA printers which are optimized for high-quality detail and accuracy with the materials they utilize.
