Introduction to FDM 3D Printing

What is FDM 3D printing?
What is FDM 3D printing?
FDM can realise complex geometries but due to the restrictions of the process any overhanging features will require support material which needs to be removed post process.

Our FDM 3D Printing Service

Fused Deposition Modelling or FDM is one of the more common 3D printing technologies and also one of the most versatile. FDM builds parts by extruding plastic filament material through a nozzle and laying it down on the build chamber one layer at a time. FDM can realise complex geometries but due to the restrictions of the process any overhanging features will require support material which needs to be removed post process.

Design Guidelines For FDM
TIPS & TRICKS
Reduce weight to save costs
Add escape holes for resin in closed sections
Fillet walls and pins for extra strength
TOLERANCES
± 0.3 mm is standard.
OVERHANGS
Not a problem for FDM due to the supports. Unsupported overhangs will warp.
OVERHANGS
WALLS
FDM can manage very thin walls but HLH do not recommend anything under 0.8 – 1mm.
WALLS
HOLES & SLOTS
We recommend a minimum of 0.5mm but the larger the better especially as wall thickness or depth increases.

TEXT & ENGRAVED DETAILS
Are at risk of closing up if not designed with 0.5mm > minimum height.

MATING PARTS
Minimum 0.5mm gap between axel and bore or other moving parts.
