Characterization and evaluation of a PMMA‐based 3D printing process

Abstract

Purpose

The purpose of this paper is to characterize and evaluate a new 3D‐printing process based on Poly(methyl methacrylate) (PMMA).

Design/methodology/approach

A benchmark part and standard parts were designed, printed by a 3D‐printer and characterized.

Findings

3D printed PMMA parts have a tensile strength of 2.91 MPa and a modulus of elasticity of 223 MPa. The mechanical properties can be improved by infiltrations with epoxy (tensile strength: 26.6 MPa, modulus of elasticity: 1,190 MPa). The surface quality of the parts can be improved by infiltration with wax for usage as lost models. The minimum feature size is 0.3 mm.

Research limitations/implications

The PMMA‐based 3D printing process can be used for manufacturing concept models, functional parts and lost models for investment casting.

Originality/value

This is the first paper investigating a PMMA‐based 3D printing process.
