Understanding Material Differences in Additive Manufacturing

Choosing the right material is one of the most important steps in additive manufacturing. Each material family offers different levels of strength, durability, heat resistance and surface quality — and these differences directly affect performance, appearance and cost. Whether you’re comparing standard polymers, engineering-grade nylons or high-performance materials, understanding the basics makes it easier to select the right option for your application. This simple overview helps clarify how materials behave and what to expect from them in real-world use.

Our Main Materials

PA12 White (SLS)

Detail & clean surface

Nylon material with sharp edges and smooth surface, ideal for visual models, small components and parts where cosmetic detail matters.

PA12 Gray (MJF)

Strength & precision

Versatile engineering nylon with high strength and dimensional stability, well suited for functional prototypes and production parts.

TPU (SLS)

Flexible & elastic

Flexible material for seals, bellows, hinges and vibration-damped components that need repeated bending without cracking.

PA12GF / PA12GB (SLS)

Stiff & dimensionally stable

Glass-filled nylon with high stiffness and low warpage, ideal for jigs, fixtures, flat parts and structural components.

ESD PA12 (MJF)

Electronics-safe

Static-dissipative nylon for housings, fixtures and tools used near sensitive electronics or ESD-critical environments.

      How do material choices like PLA vs PETG or PA11 vs PA12 affect 3D printing cost?
    
      Material differences have a major impact on how much 3D printing costs. PLA vs PETG is usually a small price shift, but PA11 vs PA12 can change cost more since they are engineering-grade nylons with different performance levels. Stronger or more specialized materials generally increase price.
    
      Is 3D printing expensive if I need strong or functional parts?
    
      It depends on what strength level you need. Standard materials remain affordable, while choosing one of the strongest 3D printing materials—like reinforced nylon or high-performance polymers—raises the cost due to advanced processing and higher durability requirements.
    
      What is the most cost-efficient way to choose between PLA vs PETG or PA11 vs PA12?
    
      Use lower-cost materials like PLA or PETG for prototypes, and choose PA11 or PA12 only when functional strength or accuracy is needed. Matching your part's requirements to the right material prevents over-engineering and keeps 3D printing cost as low as possible—even when considering the strongest 3D printing material options.
