Because of their accuracy and ability to reproduce fine details, stereolithography models are ideal for use as concept models, form and fit studies and as master patterns for a variety of molding techniques. Options for finishing include color-matched painting, texturing and pad printing to give your model a “production quality” look and feel. SLA models and patterns can be produced in a matter of hours from any popular CAD system. Starting with 3D CAD geometry, Solid Concepts’ engineers will guide your most demanding project through every step of the process to guarantee timely delivery. In-house developed 3D viewing and translation software, dedicated quality department and special finishing techniques make it possible for Solid Concepts to provide the highest level of quality at competitive prices.
SLA Technology Overview
|Applications||Layer Thickness||Envelope (XxYxZ)||Lead Time*||Tolerance**|
|Standard||Good for prototypes and master patterns that need to be built quickly and economically||0.007″||Unlimited||2-5 Days||± 0.015″ or± 0.002″/”|
|Premium||Excellent for prototypes and master patterns; provides excellent detail and requires less finishing work||0.005″||Unlimited||2-5 Days||± 0.015″ or± 0.0015″/”|
|HDSL||Provides exceptional detail in less time, requiring less post finishing work; suitable for high-quality parts and patterns||0.004″||25″ x 29″ x 21″||2-5 Days||± 0.010″ or± 0.001″/”|
SLA Standard is the fastest and most economical stereolithography process available at Solid Concepts and is available for a number of materials and applications. This process is suitable for prototypes and master patterns that need to be built quickly. Typical SLA Standard tolerances are ± .015″ or ± .002″/” (whichever is greater), however tighter tolerances may be available on a case-by-case basis.
Built in 0.007″ layer thicknesses, SLA Standard offers good feature detail and sidewall characteristics, but requires more finishing work than SLA Premium and HDSL to get rid of layer lines. SLA Standard is suitable for parts of any size and offers an unlimited build envelope making large parts no problem for our finishing department. When you pair the largest SLA machine available on the market with our proprietary knowledge of large part assembly you can expect extremely accurate large geometries.
SLA Premium is an excellent option for prototypes and master patterns, offering better accuracy and detail than SLA Standard while producing parts faster than HDSL. Typical SLA Premium tolerances are ± .015″ or ± .0015″/” (whichever is greater), however tighter tolerances may be available on a case-by-case basis.
Built in 0.005″ layer thicknesses, SLA Premium produces parts with excellent features and requires less finishing work that our SLA Standard process. With an unlimited build envelope, large parts with fine feature detail are readily available through our finishing department. Choose from a wide variety of SLA materials including clear Accura 60.
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.
