HDSL (High-Definition Stereolithography) offers the best accuracy available in SLA. This technology uses SC 5500 material to produce high-quality prototypes and master patterns that do not require extensive hand finishing. Typical HDSL tolerances are .010" or ± .001"/" (whichever is greater), however tighter tolerances may be available on a case-by-case basis.

With a layer thickness of 0.004" to 0.006", HDSL's thin layers combined with the highly accurate SC 5500 material enable the production of fine feature details with more precision than both SLA Standard and SLA Premium. Thinner layer thickness also equates to a better raw surface finish and better reproduction of slow sloping surfaces. While PolyJet HD offers the absolute best available detail and edge visualization in photocurables, it is recommended for small parts and prototypes. HDSL is ideal for parts and prototypes that are slightly larger in size but still require exceptional detail.
