Best 3D Materials for Printing Prototypes

 Best 3D Materials for Printing Prototypes

While 3D printing is one of the best prototyping methods out there, you need to choose the best materials to get the most out of your project. There are several materials for 3D printing prototypes, and your choice depends on your project’s needs. Here are some of the most used materials for 3d prototype printing.

Nylon PA12

This is a white plastic material, and it is among the most affordable materials for prototyping. Despite its relatively cheap cost, Nylon PA12 has excellent mechanical properties. It comes from fine polyamide powder, making it perfect for prototyping and production runs. This 3D printing material works best with Selective Laser Sintering (SLS) technology. 

Multi Jet Fusion PA12

This material is a grey plastic, perfect for prototyping and production. The raw version of the Multi Jet Fusion PA12 is the cheapest option on the market. You can easily make changes at low costs. Moreover, using this material gives you abrasion- and scratch-resistant products. This makes them useful for prototype testing. The Multi Jet Fusion PA12 is also stable to weather, UV stabilized, and light stabilized. Therefore, it is a perfect option for testing in outdoor conditions. 

Prototyping Resin

This resin is more suitable for non-functional prototypes, and you don’t want to use it for large production runs. Whenever you wish to manufacture highly detailed components, prototyping resin is a perfect choice. It offers smooth surface finishes, similar to products manufactured with plastic injection molding. This material works best with stereolithography (SLA). 


Fused Deposition Modeling (FDM) is an interesting technique, particularly useful for Polylactic acid (PLA) filaments. PLA is a user-friendly material with high stiffness and strength. It has a low printing temperature and minimal warping, making it one of the easiest 3D printing materials. It is also an inexpensive material, creating reliable parts for many different applications. If aesthetics and fine details are a major concern, PLA should be your go-to material. 


If your 3D printing prototyping project requires a flexible plastic, TPU is the perfect solution. This material has the properties of rubber, including high elasticity and high strength. Therefore, it would fit your prototyping project if you need something flexible. Components from this material are resistant to fatigue and stress, and it is also a great choice for final products.  


Rapid 3D prototyping is an effective manufacturing process for faster and better engineering. It speeds up your workflows and removes bottlenecks of the traditional prototyping cycle. Using 3D printing prototyping saves cost and reduces time to market while offering easier design testing and overall prototyping advantages. Before diving into any 3D printing project, you need to consider the manufacturing partner you will work with.
