The benefits of SLS are amazing.  This powder bed fusion technology requires no support structures allowing freedom of design with part properties comparable to injection molding. However, the technology is not for the faint at heart. This complex array of thermal and laser energy with variations in powder requires constant monitoring and validation of the process.

SLA is a photocurable resin process.  This technology produces the highest quality prints with amazing accuracy and detail.  A wide range of thermoset resins are available to meet many demanding applications.  Whether you need functional prototypes or crystal clear test pieces, SLA is a great choice.  Most RTV master patterns are produced with SLA.
