Numerical simulation of additive manufacturing of polymers and polymer-based composites (original) (raw)

Structure and Properties of Additive Manufactured Polymer Components, 2020

Abstract

Abstract Plastic part complexity has historically been strongly driving part cost. Recent developments of additive technologies have led to a shift from rapid prototyping to production of actual end-use parts, thus widening the range of design possibilities. By opposition with the so-called now subtractive methods, additive manufacturing (AM) regroups all manufacturing processes allowing to process parts from 3D numerical CAD model by building them layer by layer. The now irrelevant need for specific mold tooling design allows to produce low volume of highly complex parts in less time. Among additive processes of polymers and polymer-based composites, the most mature and industrially widespread are selective laser sintering (SLS) and fused filament fabrication (FFF), sometimes referred to as fused deposition modeling (FDM). In FFF, fused material filaments are deposited through a moving head while in SLS, powdered material is sintered using a laser heat source.
