Design guidelines for 3D printing

Few and simple rules to design the best and get the most out of your 3D design

FILE FORMATS
stl, .step, .stp
Only files with SINGLE parts are accepted.

MATERIALS AND MAX BUILDING VOLUME
Nylon PA12: 380x284x380 mm (15×11.2×15 in) • 3D printed with HP 5210 MJF
Nylon PA11: 380x284x380 mm (15×11.2×15 in) • 3D printed with HP 5210 MJF
Grey resin ABS like: 250x152x390 mm (9.8×5.9×15.3 in)• 3D printed with LED MSLA +4KSPER™

MINIMUM TICKNESS
Our 3D printing technologies can manage very thin walls but but to be sure of providing a quality product we only print walls with a thickness of 1mm or more.


MATING CONNECTIONS
Parts with mating connections need 1 mm gap between every wall. We only accept single part files, if not chained together.



HOLES
Minimum diameter of holes is 1 mm and every hole must be maximum 5 times the diameter to be cleaned properly. On blind holes we suggest to add service holes to remove the powder.



TEXT, LOGOS and EMBOSSED FEATURES
To get the best results we suggest to keep the elements of these features at least 2 mm in height or thickness.



SLOTS
A 1 mm gap between walls is required, proportional to the height of the walls.



EMPTY/HOLLOW PARTS
In the case of hollow or empty parts, at least 2 holes of 8 mm in diameter must be drawn to allow construction material to be discharged.

THIN PLANAR PARTS – WARPAGES

We strongly recommend that you do not design large flat plains in dimensions like an A4 page. In most cases, your model will deform. This process is called “warping”. Even if you create support ribs under your plane, it doesn’t solve the problem. It increases the chance of deformation even more. The key here is to avoid big flat planes.
