Key design considerations — Widest colour range in our FDM lineup. Annealing can raise heat resistance but changes dimensions — discuss if needed.

FDM Standard

PETG

Tougher than PLA with better layer adhesion and chemical resistance. A reliable all-rounder for functional enclosures, brackets, and parts that need modest flexibility before fracture.

  • Snap-fit prototypes with moderate deflection
  • Guards, covers and workshop tooling

Avoid where

  • Sustained temperatures above ~70 °C
  • Maximum stiffness or load-bearing structural parts
  • True optical clarity; clear grades are better treated as translucent covers, guards, or light-diffusing parts

FDM Premium

TPU 95A

Shore 95A flexible filament — rubber-like elasticity with high elongation at break. Our go-to for gaskets, grips, bumpers, and compliant interfaces.

Tensile
25–40 MPa
Density
1.20 g/cm³
Elongation
450–650 %
FlexibleAbrasion resistantHigh elongationSlow to print

Best used for

  • Seal-style interfaces, gasket-style parts, grips, bumpers, dampers, and compliant mounts
  • Snap-on covers with flexure
  • Wear pads and soft-touch interfaces

Avoid where

  • Rigid structural load paths
  • High-precision threaded features
  • Sustained elevated temperatures without review

Available colours

Typical stock — confirm at quote for your batch

  • Black
  • White
  • Red

Key design considerations — HDT is not meaningful for elastomers — expect increased flexibility, creep, or compression set at elevated temperatures; confirm if the part will see sustained heat.

FDM Premium

PA-CF

Carbon-fibre reinforced nylon, typically PA12-CF. A stiff, heat-resistant option for jigs, brackets, drill guides, and production fixtures where the load path can be designed around FDM layer direction — our stiffest standard FDM option, and strongest in many correctly oriented applications.

Tensile
70–90 MPa
HDT
125–135 °C
Density
1.06 g/cm³
Elongation

Carbon fibreHigh stiffnessHeat resistantLow moisture uptake vs PA6

Best used for

  • Jigs, fixtures, and drill guides
  • Stiff prototype brackets, fixtures and non-safety-critical frames
  • Metal-replacement concept parts where the load path, orientation, and safety factor are reviewed
  • Parts requiring dimensional stability in workshop conditions

Avoid where

  • Cosmetic show surfaces (matte, fibre texture)
  • High-impact snap-fits (brittle elongation ~3–5 %)
  • Applications requiring food or medical certification

Available colours

Typical stock — confirm at quote for your batch

  • Black · CF-filled — dark finish only
  • Dark grey

Key design considerations — Annealing can improve heat performance but may change dimensions; use only where planned into the design. XY tensile values shown; Z-layer strength is lower (typical anisotropy ~1.4–1.8×).

FDM Premium

Polycarbonate (PC)

High-performance engineering plastic with excellent heat resistance and impact toughness. Clear grades are useful for translucent covers, guards, and light-diffusing parts, but not optical-grade clarity as printed.

Tensile
55–65 MPa
HDT
110–120 °C
Density

High heatImpact toughClear/translucent optionDemanding to print

Best used for

  • High-temperature functional prototypes
  • Translucent covers and light diffusers (clear grade — not optical-grade by default)
  • Load-bearing parts requiring toughness, subject to design review of application, orientation and safety factor
  • Prototype electrical housings and isolation components where certification is not required

Avoid where

  • Large flat parts without warping risk management
  • Fine-detail cosmetic models at sub-0.2 mm features
  • Budget-sensitive runs where PETG or ABS suffices

Properties shown are typical datasheet-based ranges from manufacturer TDS and published test data. Actual finished-part performance depends on print orientation, geometry, wall structure, infill, processing conditions, material supplier and operating environment. We confirm suitability for your application at quote stage — these values are not guaranteed finished-part performance.

What we check before printing

Material fit

We confirm the selected filament matches your load, temperature, and environment before production starts.

Orientation

Build direction is chosen to balance strength, surface finish, and support contact on critical faces.

Geometry review

Wall thickness, overhangs, and tolerances are checked against FDM design rules for your material.

Colour & finish

Stock colours confirmed at quote. Custom colours and post-processing discussed for repeat orders.
