“What If” we can use material, only there where needed…
40% weight saving over original component design
CONVENTIONAL OPTIMISED
flow optimisation
“What If” we can create complex channels inside our products
2.900 cm³ vs 244 cm³
19.2 kg vs 1,2 kg
210 mm vs 85 mm

“What If” we can add multiple functionalities in one part
25% lighter
18 parts to 1 part
5 times more durable due to improved cooling system

“3D SAND PRINTING AND CASTING A PUMP CASING (Ø1200 X 800 MM) ”
MASTERCLASS “DESIGN FOR AM”
“ forget what you know
start from the function of the part
use as less material as possible
complexity for free ”
DESIGN FOR ADDITIVE MANUFACTURING

DESIGN CONSIDERATIONS COMPLEXITY
* Within the same bounderies 34
“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

“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."

“the thicker the layer, the rougher the surface
the thinner the layer, the longer the build time”

‣ 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

‣ Same as build material (fused or non-fused)
‣ Second material

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
