Design Guidelines: Stereolithography
Our basic guidelines for stereolithography include important design considerations to help improve part manufacturability, enhance cosmetic appearance, and reduce overall production time.
We offer a number of secondary services to further enhance your 3D-printed project design or finish.
|NORMAL RESOLUTION||736mm x 635mm x 533mm|
|HIGH RESOLUTION||247mm x 245mm x 250mm|

Minimum Feature Size
|NORMAL RESOLUTION||0.25mm for the XY draw plane (0.406mm for the Z build direction)|
|HIGH RESOLUTION||0.13mm for the XY draw plane (0.406mm for the Z build direction)|
For parts that are built in High Resolution (HR): The tolerances for well-designed parts are in the X / Y direction ± 0.05mm plus an additional ± 0.001mm / mm; In Z direction ± 0.13mm plus additional ± 0.001mm / mm.
For parts that are built in Normal Resolution (NR): The tolerances for well-designed parts are in the X / Y direction ± 0.1mm plus an additional ± 0.001mm / mm; In Z direction ± 0.13mm plus additional ± 0.001mm / mm.
Typically, tolerances are expected and achieved on well-designed parts.
|UNFINISHED||Dots, or standing"nibs," remain evident on the bottom of the part from the support structure remnants.|
||Supported surfaces are sanded down to eliminate the support nibs.|
||Supported surfaces are sanded, and the entire part is finely blasted for a consistent look. Note that the layers are still present.|
Electro-plating is a process that enables the production of parts with a special surface (commonly referred to as chromium plating). The electro-plating gives parts the look, feel, and strength of metal, but without the weight. It also improves part strength, stiffness, and impact/ temperature resistance.
Finished parts (or areas on the part), can be coated with copper or chrome. This is widely used in applications for the automotive sector or in electrical engineering.
Electro-forming is also possible. This process consists of metal coating a component and then removing the original part so that only the metal part remains.
Individual finishing of parts
Our surface finishing service offers individual processing of parts (or entire assemblies).
Parts can be painted in our specially equipped paint shop and the specialist team looks after your project from preparation to shipping of the parts.
Examples of our additional services are:
- Project support by our account management team
- Paint and varnish supplied to all applicable standards (RAL, Pantone, ...)
- Surface treatment of finished parts (e.g. grinding and polishing)
- Painting (including all preparation work)
- Design according to specification
- Assembly (also beyond the size of the installation space)

Our stereolithography machines consists of Vipers, ProJets, and iPros. In high-resolution mode, Vipers and ProJets can make parts with extremely tiny features and crisp details, while in normal-resolution mode, they can build cost-effective parts very quickly.
iPros have extremely large build volumes at 736mm by 635mm by 533mm, yet are still able to image highly detailed parts easily.
