use as less material as possible
complexity for free ”
DESIGN FOR ADDITIVE MANUFACTURING
33
“Translating the desired design features into CAD geometry can be difficult
due to the increased part complexity.
Without good knowledge of the AM capabilities and CAD design,
this proces will be time consuming.”
DESIGN CONSIDERATIONS CHALLENGES
35
‣ available MATERIALS
‣ know the printer’s limitations
‣ HIGH PRICE of industrial machines
‣ CERTIFICATION of materials and technologies
‣ SURFACE QUALITY (supports, post-processing)
‣ QTY >< DIMENSIONS >< MATERIALS><PRICE
DESIGN CONSIDERATIONS THINGS TO CONSIDER LIMITATIONS
36

“A channel needs to be round”
DESIGN CONSIDERATIONS FORGET WHAT YOU KNOW
Psychology inertia: ‣ "the way that I am used to doing it." ‣ "You are not allowed to do that!" ‣ "Tradition demands that it be done this way!" ‣ "You have been given the information, and the information is true."
37
…part orientation
“the thicker the layer, the rougher the surface
the thinner the layer, the longer the build time”
…layer thickness
DESIGN CONSIDERATIONS BUILD TIME CAN BE INFLUENCED BY

‣ Depending on the technology and material
‣ Support the overhanging surfaces
‣ Increase thermal conductivity
‣ Connect the part to the base plate
‣ Rule of thumb <45°
NOTE: Supports = waste
DESIGN CONSIDERATIONS SUPPORT STRUCTURES

Reduce the thickness of your part to:
‣ Reduce the amount of material
‣ Reduce the risk of geometric deformations (with thermal technologies)
‣ Reduce the weight of your part
‣ Speed up the process
MATERIAL DO I NEED ALL THIS MATERIAL?

DESIGN CONSIDERATIONS SPACE BETWEEN PARTS
‣ Keep sufficient space between separate parts.
‣ Gap size is technology specific
‣ Reference gap = 0,4mm

49
Design the features of the part in function of the technology
‣ Wall thickness
‣ Size and orientation of holes
‣ Details like embossing and debossing
DESIGN CONSIDERATIONS FEATURE SIZE

‣ Easy traceability
‣ Connect a label to your product
‣ Emboss / deboss the part number or name on your product itself
!! Design the tag size according to the production technology
