Stereolithography (SLA)/(DLP)

SLA/DLP 3D Printing Services

Stereolithography (SLA) and digital light processing (DLP) printers make use of the oldest 3D printing technology - vat photopolymerization. Both technologies use light to cure and harden specific areas of resin to form a solid part. SLA printers do this with a laser that travels over the cross-sectional area of each layer of the part while DLP printers use a digital light projector screen to flash a single image of each layer all at once.

The differences between SLM and DMLS come down to the fundamentals of the particle bonding process (and also patents): SLM uses metal powders with a single melting temperature and fully melts the particles, while in DMLS the powder is composed of materials with variable melting points that fuse on a molecular level at elevated temperatures.

Application

  •   SLA is most suitable for visual applications where an injection mold-like, smooth surface finish, and a high level of feature detail are required.
  •   Dental Molds.
  •   Electronics Enclosures.
  •   Miniature Models (Diorama, Sculptures).
