Stereolithography (SL or SLA from Stereolithography Aparatus) is an additive manufacturing technology for creating three-dimensional (3D) objects from CAD drawings such as prototypes, production models and parts.
"Stereolithography (SL or SLA from Stereolithography Apparatus) is an additive manufacturing process using a vat of liquid UV-curable photopolymer "resin" and a UV laser to build parts one layer at a time. On each layer, the laser beam traces a cross-section pattern of the part onto the surface of the liquid resin. Exposure to the UV laser light cures, solidifies the pattern traced on the resin and adheres it to the layer below."
Stereolithography gives you an easy and fast way to convert CAD drawings to real objects. RobHopeless wanted a better printing resolution and quality than the currently 3D printer kits such as Makerbot, Ultimaker or Reprap can make. So he decided to make his own printer.
The quality he has achieved is quite good and he can now make some beautiful prints. The only negative point is that the cost is high. Comparing to ABS or PLA for the plastic extrusion printers the cost of UV/Visible resins is about 4~5 times higher, 1 Liter around $200 - $250.
This project is Open Source Hardware. RobHopeless has wroten very detailed building process.
