3D printing materials: A guide to the right material
Which material is right for your 3D printing projects? This guide shows the most important materials, their properties and applications - from thermoplastics to metal. This will help you quickly find the right solution for prototypes and series.
Introduction
Choosing the right 3D printing materials is one of the most important steps in additive manufacturing. This is because every material has specific properties - be it high strength, temperature resistance, flexibility or chemical resistance. The material has a major influence on whether a component functions reliably. It also determines how well it can be printed and what post-processing is required.
In this guide, you will learn about the material classes in 3D printing. You will find out which materials are suitable for which processes. We will also show you how to find the best material for your application. This applies to both prototypes and series production.
Why the choice of 3D printing material is crucial
Choosing the right 3D printing material is crucial for the function, quality and cost-effectiveness of a component. Every material - whether thermoplastic, metal, resin or ceramic - has specific properties such as strength, temperature resistance, flexibility or chemical resistance.
These have a direct impact on durability, dimensional accuracy and usability in real operation. Anyone who has a component manufactured should therefore adapt the material specifically to the requirements.
A good choice of material reduces waste. It lowers production costs and improves results. This applies to prototypes and series production.

Post-processing gives 3D-printed components their final quality - whether dimensional accuracy, smooth surface or functional properties. The processes differ significantly depending on the material class.
Properties:
- Thermoplastics (e.g. PLA, ABS, PETG): Manual or mechanical post-processing by grinding, milling or chemical smoothing (e.g. acetone vapor for ABS). Painting or coating also possible for optical applications.
- Resins (SLA, DLP)UV post-curing to achieve full strength, then sanding, polishing, painting or coating. Ideal for smooth visible surfaces.
