Example: A Maker creating custom tabletop game pieces at home.

ABS - Stronger Polymer with Better Heat Resistance

It’s a strong material suited for enclosures, jigs and fixtures, automotive prototypes, and any other functional parts. If your part needs to perform well outdoors, consider ASA filament – a UV-resistant alternative also used in FDM printing.

Pros: Tough, heat-resistant, good for mechanical parts.

Cons: Prone to warping; requires an enclosed printer.

Best Use: Enclosures, jigs, automotive prototypes.

Example: An Engineer producing custom housing for electronic sensors.

TPU - Flexible and Durable FDM Material

TPU is the ultimate material for flexible components such as seals, gaskets, wearable prototypes, and other elastic parts. It offers a rubber-like, abrasion-resistant, and durable material, although it requires a slower print speed and direct-drive extruders.

Pros: Rubber-like elasticity, abrasion-resistant.

Cons: Slower print speeds, needs a direct-drive extruder.

Best Use: Seals, gaskets, wearables, shock-absorbing parts.

Nylon (PA12)  - High-Strength, Wear- and Heat-Resistant

PA12 (Polyamide powder) is used in SLS (Selective Laser Sintering) technology and is known for its excellent strength and heat resistance. PA12 is best for mechanical parts, industrial prototypes, and functional gears.  

A key benefit of SLS technology is the design freedom - thanks to its powder-based material approach, you can achieve precise objects with complex geometry in an affordable way.

Pros: Excellent mechanical strength, high heat deflection.

Cons: Absorbs moisture, requires drying before use.

Best Use: Industrial gears, mechanical joints, load-bearing prototypes.

Example: Automotive team printing durable hinge components.

High-Detail Models & Precision Components (SLA)

SLA (Sterelithography) technology, the oldest 3D printing method (invented nearly 40 years ago), works with a variety of photopolymer resins that solidify when exposed to ultraviolet (UV) light. Generally, we can say that this 3D printing method delivers objects with ultra-fine details and a smooth surface, ideal for applications like display models, jewellery, and dental molds.

Best for: dental models, jewelry casting, highly detailed visual prototypes.

Technology: Stereolithography (SLA).

Standard Resin - High Resolution, Low Strength

There are different types of resins available on the market. The standard resin is perfect for visual and intricate prototypes, or figurines that don’t require high strength. SLA parts are typically fragile models, and to reach a smooth surface, post-processing is necessary.

Pros: Smooth surface finish, fine detail reproduction.

Cons: Brittle, limited mechanical performance.

Best Use: Display models, intricate figurines.

Engineering Resin - Functional & Detailed

Compared to the Standard Resin, the Engineering one is ideal for detailed parts with higher mechanical performance. Tough Resin is suitable for snap-fit parts, enclosures, and functional components used in engineering testing, like housings.

Pros: Higher toughness, snap-fit capability.

Cons: Not UV stable, indoor use recommended.

Best Use: Functional prototypes, housings, dental models.

Transparent Resin - Optical & Fluid Applications

Clear resin is great for optical, light diffusion models, or microfluidic devices. The 8001 Resin offers good strength and dimensional stability, along with being translucent.

Pros: Light-transmitting, dimensionally stable.

Cons: May yellow over time without UV protection.

Best Use: Optical models, fluid channels, microfluidic devices.

JLC3DP offers a total of eleven resin types with varying levels of heat-resistance, toughness, and colour options. The latest addition is the high-strength JLC Temp Resin, with heat-deflection properties up to 101℃.

Industrial-grade Metal Parts (SLM & Binder Jetting)

JLC3DP offers two technologies when it comes to metal 3D printing. While SLM (Selective Laser Melting) uses a laser to selectively melt metal powder layer by layer, Binder Jetting works with a printhead to deposit liquid binder onto a powder bed.

Both methods produce strong, end-use functional metal parts with corrosion resistance, making them perfect for industrial, aerospace, or medical or marine applications.

Best for: aerospace, medical, automotive, marine applications.

Technologies: Selective Laser Melting (SLM) & Binder Jetting.

Stainless Steel 316L - Corrosion-Resistant All-Rounder

Stainless steel provides high strength and toughness even at high temperatures, making it ideal for industrial components, marine hardware, mechanical tooling, and surgical instruments in demanding environments.

Pros: High strength, excellent corrosion resistance.

Cons: Heavier than titanium.

Best Use: Mechanical tooling, marine hardware, surgical instruments.

Titanium TC4 - Lightweight High-Performance Metal

Some of the key properties of titanium are its lightweight feature, biocompatibility, and corrosion resistance. With its low density and good toughness, the medical, automotive, and aerospace industries can use titanium for high-performing parts, where high-strength is important.

Pros: High strength-to-weight ratio, biocompatible.

Cons: More expensive than stainless steel.

Best Use: Aerospace brackets, medical implants, high-performance automotive parts.

Material Selection Workflow

Define your application – Start by clarifying whether your part is decorative, a functional prototype, or a final end-use product. This will guide your material choice and help avoid over- or under-engineering.

Assess the environment – Consider where and how the part will be used. Indoor parts may prioritize aesthetics, while outdoor components must resist UV, moisture, and temperature swings. For industrial settings, factor in heat and chemical exposure.

Pick the right technology – Match material and printing method. FDM offers affordable, versatile polymers for quick prototyping. SLA delivers high-resolution detail for models and precision parts. SLM or Binder Jetting provides metal strength for demanding, load-bearing applications.

Compare specifications – Review data sheets for tensile strength, heat deflection temperature (HDT), shrinkage rates, and other performance metrics. This ensures the chosen material meets your mechanical and thermal requirements.

Get a test print – Before committing to full production, order a sample or small batch. This validates the material’s performance, surface finish, and dimensional accuracy under real-world conditions, reducing costly rework later.
