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. These services are available when ordering a part manufactured by Protolabs.
|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.|
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.
