MINIMUM THICKNESS

SLS and MJF technologies can manage very thin walls but to make 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 achieve the best result 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 powder 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 and increases the chance of deformation even more. The key here is to avoid big flat planes.
Following these simple rules will make it much easier for you to get great results. If in doubt, do not hesitate to contact us.

MJF

Processes like infrared heating along with fusing are used in the process of MJF or Multi Jet Fusion 3D printing technology. The major advantage is that you can indulge in the direct fabrication of complex parts with the help of this process in a cost-effective manner. This is a design guide for the MJF technology of 3D printing.

FDM

If low-cost prototyping is your main aim without hampering the quality, then FDM or Fused Deposition Modeling is definitely your best option. Here is a design guide for this type of 3D printing technology.
