In this blog post we are going to see what materials can be 3D printed and what are the Strongest and Flexible 3D Printing materials are available in the Additive Manufacturing Industries

Polymers available on the market

The typical polymers used during processes involving thermo plastics or plastics that are heated in some kind of a semi-liquid condition and near to the melting point are Polycarbonate (PC), Acrylonitrile Butadiene Styrene (ABS), Poly Ether Ester Cetone (PEEK), Polyetherimide (ULTEM) and Nylon. The particles are bonded and solidified until they are extruded. Fused deposition (FDM), jetting (Inkjet), and selective laser sintering ( SLS) are Additive Manufacturing methods that utilize thermoplastics. SLA and Direct Ink Writing (DIW) utilize liquid thermosetting polymers or polymers that seem to be solids after curing.

3D Printer Material Strength

Under the melting stage, a chemical reaction takes place, contributing to a durable substance. Polymers in SLA and DIW are formulated to fulfil unique properties, particularly physicochemical properties. For example, every layer will support itself and allow several layers to be printed while retaining the geometry crafted. It applies rheologically to resins that have a yield stress while they are subjected to high oscillation stresses, meaning that the resin becomes solid at rest (low stress) and liquid like while flowing (high stress). The inadequate feedstock availability for procurement is one of the big obstacles of polymer 3D printing.

Polymers end up losing mechanical strength for load – carrying applications in particular in a pure form. In addition of fillers, including such as silica and carbon fibres with polymers, are often made a high mechanical strength materials. In fact, incorporating additives increases the performance of products by introducing flexibility to components like the getter, UV and radiation tolerance, as well as anti-fouling performance.
