FDM MANUFACTURING

FDM is a 3D printing method where a layer of material is melted and fused while it is positioned in a structured way to create an object. FDM is useful when doing rapid-prototyping or when you need large format functional prints.

DLP MANUFACTURING

DLP stands for digital light processing and is a type of vat polymerization. Vat polymerization 3D printing technologies make use of a (liquid) photopolymer resin which is able to cure (solidify) under a light source. DLP creates high detail objects with a smooth finish but is limited to smaller objects.

3D PRINTING GUIDELINE

WHAT FILE TYPE, SCALE AND UNITS DO YOU NEED?

STL and OBJ are preferred for all 3D printing materials. 

File preparations may be required for STP/STEP, 3DS, 3DM and DWG. 

All models should be scaled 1:1 as per intended final print size. 

WHAT IS THE LARGEST YOU CAN PRINT?

FDM PLASTIC: 500 x 500 x 500mm and 605 x 305 x 205mm

DLP RESIN: 155 x 115 x 65mm

WHAT ARE THE TOLERANCES OF FDM?

Layer height: minimum 0.1mm, typically 0.2mm

Precision Tolerances: +/- 1mm

Overhang Support: Max 45 degree overhangs over 45 degrees will require support materials. 

Max Bridging: 5mm, surface finish will sag and deteriorate beyond this limit.

Minimum detail size: 0.8mm

Minimum supported wall thickness: 1mm, 2mm if unsupported.

Minimum supported wire thickness: 1mm, 2mm if unsupported.

Infill Density: 0% to 100%

WHAT IS THE TOLERANCE OF DLP?

Hardness: 84D

Shrinkage: 3.72-4.24%

Bending Strength: 59-70MPa

Extension Strength: 36-52MPa

Elongation at Break: 11%-22%
