Additive manufacturing principle

Make a 3D part by stacking 2D slices/layers

Additive manufacturing principle

Virtual world Real world

AM machine

STEP 1 : *.STL File

STL = Standard Triangulation Language. Main information : Part boundaries

STEP 1 : *.STL File

Different Sources : Standard CAD file conversion (*.STEP, *.IGES). 3D scan (Optic, RX,…) of existing part. Direct drawing and export (Blender, CATIA,

ProEngineer,…).

Note : have a *.STEP or *.IGES from an *.STL is not so straightforward.

STEP 1 : *.STL File

Different Sources : Online data bases

STEP 2 : Part preparation

Important step : Find optimal position Downward facing surfaces will have a worst

quality -> over thickness added on critical areas of the *.STL file for future post-machining. Some small manipulations can be done like fill

holes, hollow the part, cut some areas, add labels, split parts in different shells, Boolean operations,… A good knowledge leads to better part quality

STEP 3 : manufacturing

Almost all the materials are available (metal, ceramics, polymers) by choosing the good technology.

Not as accurate as traditional technologies (best 0,1 mm) and surface roughness sometimes significant post finishing needed.

Quite limited maximum part size (mean : 200x200x300 mm)

Really complex shapes are achievable. Parts can be as functional as traditional ones or

pure esthetic

Technologies classification

ASTM choice (norm ASTM F2792) : Binder Jetting : Liquid bonding agent is selectively deposited

to join powder materials. Direct Energy Deposition : Thermal energy is used to fuse

materials by melting as they are being deposited. Material Extrusion : Material is selectively dispensed through

a nozzle or orifice. Powder bed fusion : Thermal energy selectively fuses

regions of a powder bed. Sheet Lamination : Sheets of material are bonded to form an

object. Vat Polymerization : liquid photopolymer in a vat is

selectively cured by light-activated polymerization Material Jetting : liquid material is deposited with a printing

head and solidified (UV/IR laser, air contact,…)

Conclusion

This is a new production mean, on the same level as machining or injection molding.

AM gives the geometrical complexity, but need finishing for good part accuracy.

There are very low cost machines -> Available for everyone, not only the professionals.

Every industrial sectors will be concerned.
