FDM — Fused Deposition Modeling

Thermoplastic Filaments

FDM builds parts by extruding molten thermoplastic layer by layer. It's the most versatile technology — offering the widest range of engineering-grade materials for functional parts.

PLA

Easy to print Biodegradable

ABS

Acrylonitrile Butadiene Styrene

The classic engineering plastic. Strong, heat-resistant, and machinable. Widely used in injection molding — making it ideal for functional prototypes that mimic production parts.

Bed90–110°C
Best UseFunctional prototypes, production-like
Heat resistant Strong & machinable

PETG

PET Glycol-Modified

The best of both worlds — strength of ABS with ease of PLA. Excellent layer adhesion, food-safe options, and good chemical resistance. Great for functional parts and containers.

Temp230–250°C
Bed70–90°C
Best UseFunctional parts, containers
Food-safe option Chemical resistant

Nylon (PA6 / PA12)

Polyamide

A true engineering thermoplastic. Exceptional toughness, wear resistance, and fatigue tolerance. Used in aerospace, automotive, and industrial applications requiring long-term durability.

Bed80–100°C
Best UseGears, bearings, wear parts
High toughness Wear resistant

TPU

Thermoplastic Polyurethane

Flexible, rubber-like material with excellent abrasion resistance. Shore A hardness ranging from 85A to 95A. Ideal for seals, gaskets, protective covers, and wearable device components.

Hardness85A – 95A
Temp210–230°C
Best UseSeals, gaskets, wearables
Flexible Abrasion resistant

Carbon Fiber Nylon

Nylon + Carbon Fiber Reinforced

Nylon reinforced with chopped carbon fiber strands. Stiff, strong, and lightweight — with thermal and mechanical properties far exceeding standard nylon. Ideal for lightweight structural parts.

StrengthVery High
Weight30% lighter than ABS
Best UseStructural, lightweight parts
High stiffness Lightweight
SLS — Selective Laser Sintering

Nylon Powder Materials

SLS sinters nylon powder with a laser, building fully functional parts without support structures. Ideal for complex geometries, fine features, and durable production-grade parts.

Nylon 12 (PA12)

Polyamide 12

The workhorse SLS material. Excellent mechanical properties, good chemical resistance, and outstanding elongation at break. Suitable for functional prototypes and end-use production parts alike.

Tensile Strength~48 MPa
Flex Modulus~1,850 MPa
elongation~20%
Production-grade No supports needed Chemically resistant

Glass-Filled Nylon

Nylon 12 + Glass Beads

Nylon 12 reinforced with glass spheres. Higher stiffness and better dimensional stability than standard Nylon 12, with excellent surface quality. Slightly more brittle but much more rigid — ideal for functional testing.

Stiffness~3x standard nylon
SurfaceVery smooth
Best UseRigid functional parts
High stiffness Dimensional stability

Alumide

Nylon + Aluminum Powder

Nylon reinforced with aluminum powder — giving parts a subtle metallic sheen and significantly improved stiffness. The aluminum content also improves thermal conductivity, making it better for high-temperature applications.

StiffnessHigher than GF Nylon
FinishSubtle metallic gray
Best UseFunctional metal-replacement
Metal-filled High stiffness Metal appearance

No Support Structures

Unsintered powder self-supports — enabling complex internal geometries.

Isotropic Strength

Parts are equally strong in all directions — no weak layer lines.

High Detail

Fine features, thin walls, and complex lattices — all achievable.

Material Recycling

Unused powder is reclaimed and reused — making SLS highly efficient.

SLA — Stereolithography

Photopolymer Resins

SLA uses a laser to cure liquid photopolymer resin layer by layer — producing the highest resolution and smoothest surface finish of any 3D printing technology. Ideal for visual prototypes, dental models, and precision components.

Standard Resin

General Purpose

The most common SLA material. High detail, smooth surface finish, and excellent resolution. Ideal for visual prototypes, concept models, and display parts with fine features.

ResolutionVery High
SurfaceSmooth, injection-like
StrengthModerate
High detail Smooth finish Multiple colors

Tough / Durable Resin

ABS-like

Engineered to simulate ABS plastic — with high impact resistance, good elongation, and reliable performance under stress. The best choice for functional prototypes that need to survive real-world testing.

Impact~50 J/m
Elongation~25–40%
Best UseFunctional prototypes
High impact ABS-like Functional

Flexible Resin

Rubber-like

A soft, rubber-like material with Shore A hardness of 80A–90A. Ideal for prototyping soft-touch overmolds, gaskets, seals, and wearable device components that need flexibility and tactile feedback.

Hardness~80–90 Shore A
FeelSoft rubber

Material Selection Guide

Not Sure Which Material Is Right?

Material selection depends on your application — strength requirements, temperature exposure, surface finish needs, and budget. Here's a quick guide to help you choose, or just ask us — we give free material recommendations.

I need maximum strength & durability

Nylon 12 (SLS) or Carbon Fiber Nylon (FDM) — both offer excellent tensile strength, fatigue resistance, and long-term durability in demanding environments.

Or: Tough Resin (SLA) for high-impact functional prototypes. Glass-Filled Nylon for maximum stiffness.

I need the best surface finish

Standard Resin (SLA) produces the smoothest, most injection-molded-like surface of any 3D printing technology. Perfect for visual prototypes, consumer products, and presentation models.

Note: SLA parts may require post-processing (sanding, priming) to achieve a truly class-A surface.

I have complex geometries or fine details

Nylon 12 (SLS) — no support structures means you can print internal channels, complex lattices, and intricate features that FDM simply can't achieve. Standard Resin (SLA) for the finest details.

Tip: Unsintered SLS powder self-supports, enabling truly complex part geometries.

I'm on a tight budget

PLA (FDM) is the most cost-effective material and easy to print. For slightly more, ABS offers better mechanical properties. SLA tends to be higher cost due to resin and post-processing requirements.

Note: We offer volume pricing — larger quantities significantly reduce per-part material cost.
