Abstract
Poly-methyl methacrylate (PMMA) is a thermoplastic that has gained
increasing popularity in additive manufacturing for its transparency,
biocompatibility and dimensional stability. The mechanical properties of 3D-printed
PMMA components, however, are frequently not as good as those of components
made by conventional methods, which restricts their use in load-bearing
situations. The present review summarizes literature pertaining to recent
research on mechanical properties of 3D-printed PMMA and discusses how to
enhance the material properties. The use of nanofillers like carbon nanotubes
(CNTs), zirconia, titanium carbide, and antibacterial agents; optimization of
printing parameters such as the raster angle, layer thickness, and print speed;
and design innovations such as lattice hybridization. The literature shows that
the tensile strength can be improved by up to 58% with the reinforcement of
nanoparticles1 and strength and stiffness can be optimized
simultaneously through the optimized printing parameters4. There are
however compromises between strength and ductility and environmental aging will
severely affect mechanical properties2. This review highlights
various challenges that are currently standing in the way of the potential of
3D-printed PMMA in biomedical and engineering applications and suggests future
research avenues to overcome such challenges.
