RECOMMENDED GENERAL DESIGN GUIDELINES

Max size: 340 x 340 x 620 mm

Smallest wall thickness: 0.7 – 1 mm

Smallest detail 0.3 mm

Clearance between parts: 0.5 mm

WALL THICKNESS

Recommended wall thickness for manufactured parts: 0.7–1 mm. smaller structures can be too fragile that they may not survive the post-processing. After production the parts are cleaned and shot blasted to clear excessive powder.

CLEARANCE

When manufacturing complicated functional structures, like joints, it is recommended to use clearance of 0.5 mm. During manufacturing of the object, the powder remains between the parts as a support and it has to be removed during post-processing. If the clearance is too small, the powder compresses and may possibly melt, resulting in difficulties on separating the parts. When designing complex net-like structures it is also recommended to use the same values to avoid melting and achieve successful post-processing.

ENGRAVINGS AND EMBOSSED PATTERNS

For engravings and embossed patterns it is recommended to use a line thickness of 0.8 mm and enough height so all the shapes show clearly. The layer thickness we use in producing parts is 0.1 mm which means that you need at least 0.2 mm for a detail to show at all. It is recommended that the details are +1 mm tall so they stand out clearly.

WARPING

It is typical for big thin areas to warp during the cooling process. This effect is not avoidable. The only solution is not to have big thin areas. A4-like thin objects are not recommended for printing if warping is a problem for the end-use of the product.
