Discover key methods for selecting the best 3D printing materials for spare parts, including evaluating application requirements, technologies, and smart tools.
Picture this scenario – you have a spare part you want to 3D print. You might know that it's designed for metal 3D printing, or perhaps it's better suited as a plastic part. But, you may be unsure which specific material is the most suitable. And with so many material options out there, it's easy to feel overwhelmed.
In fact, hundreds, if not thousands, of different additive manufacturing materials are available on the market, each offering unique properties tailored to specific production technologies. On top of that, dozens of companies produce 3D printing materials, ranging from proprietary formulations to widely accessible options. Navigating this vast selection can be daunting.
Which begs the question – how do you determine the right 3D printing material for your project?
Common Methods for Choosing 3D Printing Materials
Fortunately, engineers have several methods to simplify the process of selecting 3D printing materials. You can narrow down the options by considering various factors such as application requirements, printing technologies, part functionality, and using available tools. Let’s explore these methods in more detail.
Evaluate 3D Printing Materials Based on Application Requirements
One of the most effective ways to choose a material is by aligning it with the specific needs of your part. Every application has its demands, so it’s essential to think about how the part will be used and the environment it will be exposed to.
For example, mechanical requirements such as strength, flexibility, impact resistance, or fatigue endurance may drive you to select durable materials like nylon or carbon-fiber composites. If the part faces high temperatures, thermal requirements come into play, and materials like polyetheretherketone (PEEK) or polycarbonate (PC) would be ideal. In cases where the part must resist chemicals or moisture, options like polypropylene (PP) or specialized resins are excellent choices due to their chemical resistance.

Select 3D Printing Materials Based on Manufacturing Technologies.
Certain materials work best with different 3D printing technologies. When choosing a material, consider the most suitable manufacturing process for your part.
For instance, Fused Deposition Modeling (FDM) typically uses common materials like PLA, ABS, and PETG, which are widely available and easy to print. If you require more strength or flexibility, advanced materials such as carbon fiber or TPU can also be used with FDM. Selective Laser Sintering (SLS) is a great choice for more durable parts, especially for nylon-based powders or TPU, which offer robust performance. If your focus is on fine detail, Stereolithography (SLA) is ideal due to its use of resins, though these materials may be less mechanically strong than thermoplastics.
Consider 3D Printing Materials Based on Part Function and Environment.
The function of the part and its intended environment also heavily influence material selection. If you are producing a prototype, cost-efficiency may be more important, making materials like PLA or ABS more attractive. However, you'll want higher-performing materials like carbon-reinforced nylon or metal alloys for end-use parts to ensure long-term durability.
Similarly, whether the part is load-bearing or non-load-bearing will guide your choice. Load-bearing parts require materials that can withstand stress, such as nylon, PEEK, or even metal alloys, while non-load-bearing parts can be made with more standard materials.
Use Software to Compare 3D Printing Materials More Easily
Thankfully, modern software tools can simplify material selection. 3YOURMIND’s Part Identification software allows engineers to assess part designs for 3D printing compatibility and offers a comprehensive way to compare additive manufacturing materials.
This software has been developed in collaboration with experienced producers, material suppliers, and technology providers, ensuring that it is both robust and backed by proven data. Users can compare materials side-by-side, reviewing properties such as mechanical strength, flame retardancy, corrosion resistance, and UV resistance.
