In this whitepaper, we will compare laser-based Stereolithography (SLA), Digital Light Processing (DLP), and Projection Micro Stereolithography (PµSL) and examine how each performs against the ?ve factors.
The ability to get high resolution, accuracy, and precision has long been an advantage of photopolymerization-based 3D printing, but achieving this at the micron level has, until now, been a challenge.
In this whitepaper, we will compare laser-based Stereolithography (SLA), Digital Light Processing (DLP), and Projection Micro Stereolithography (PμSL) and examine how each performs against the five factors listed below:
- Optical resolution
- Mechanical precision
- Exposure control & curing
- Interaction between parts & support structures
- Part size and tolerances
