FDM 3D Printing

Fused Deposition Modelling is our most versatile 3D printing technology — capable of producing everything from investment casting patterns in Stratment 102 to high-performance structural parts in Ultem™ 9085 and Polycarbonate. Eight materials across a wide range of applications.

FDM Material 01

Stratment 102

Proprietary FDM filament developed by Stratnel specifically for investment casting patterns. Optimised for strength, rigidity, wettability, polishability, and inter-layer adhesion — properties that prevent slurry ingress, shell cracking, and excessive residual ash. Parts cast from Stratment 102 patterns achieve a typical surface finish of 2–6 µm Ra on cast surfaces.

Property	Value
Tensile strength (XY)	>62 MPa
Flexural strength (XY)	>85 MPa
Tensile modulus (XY)	>3.1 GPa
Ash content	<0.15% — clean burnout, minimal rejection
Cast surface finish	2–6 µm Ra (geometry dependent)
Best for	Investment casting patterns, foundry pattern supply

FDM Material 02

PLA

Polylactic acid — a biodegradable thermoplastic ideal for low-cost concept models, visual prototypes, and non-functional parts. Fast to print, easy to post-process.

Property	Value
Tensile strength	45 MPa
Tensile modulus	3,500 MPa
Glass transition temperature	60°C — not suitable for elevated temperature use
Best for	Concept models, visual prototypes, non-structural parts
Colour	Multiple colours available

FDM Material 03

ABS

Acrylonitrile Butadiene Styrene — a widely used engineering thermoplastic with good impact resistance and machinability. Suitable for functional prototypes and enclosures.

Property	Value
Tensile strength	~51 MPa
Flexural strength	~74 MPa
Heat deflection temperature	92–96°C (annealed)
Best for	Functional prototypes, enclosures, snap-fit parts
Post-processing	Acetone-smoothable for improved surface finish

FDM Material 04

PETG

Polyethylene Terephthalate Glycol — combines good mechanical properties with excellent chemical resistance and toughness. Notable for very high elongation at break, making it resilient under impact and flex loading.

Property	Value
Tensile strength (yield)	57 MPa
Flexural strength	80 MPa
Elongation at break	120% — excellent toughness
Izod impact (notched)	Not breaking
Heat deflection temperature	63°C (unannealed, 1.80 MPa)
Best for	Chemical-resistant parts, functional prototypes

FDM Material 05

Polycarbonate

High-impact engineering thermoplastic with excellent temperature resistance and optical clarity. Suitable for demanding structural and functional applications.

Property	Value
Tensile strength	62 MPa
Flexural strength	78 MPa
Glass transition temperature	147°C
Deflection temperature	135°C (at 0.45 MPa)
Best for	Structural components, impact-resistant housings, and high-load mechanical parts requiring exceptional thermal stability
Note	Requires high-temperature printer — we use Intamsys platform

FDM Material 06

Ultem™ 9085

Polyetherimide (PEI) — a high-performance engineering thermoplastic with an exceptional strength-to-weight ratio, thermal stability, and FST (flame, smoke and toxicity) rating. Widely specified in aerospace, transportation, and medical applications.

Property	Value
Tensile strength	86 MPa
Bending strength	116 MPa
Impact strength	115 J/m (notched Izod)
Operating temperature	-50°C to +150°C
Glass transition temperature	186°C
Certifications	UL94 V-0 flame retardant — FST rated for aerospace and transportation
Best for	Aerospace components, lightweighting, high-temperature, and structural applications

FDM Material 07

FR-PC-ABS

Flame-retardant Polycarbonate-ABS blend. Combines the toughness of PC with the processability of ABS and adds UL94 V-0 flame retardancy. Common in electronic enclosures.

Property	Value
Tensile strength	60 MPa
Flexural strength	85 MPa
Glass transition temperature	137°C
Deflection temperature	125°C (at 0.45 MPa)
Certifications	UL94 V-0 @ 1.5mm — flame retardant
Best for	Electronic enclosures, EMS applications, flame-rated housings

FDM Material 08

ASA

Acrylonitrile Styrene Acrylate — UV-resistant engineering thermoplastic. Excellent outdoor durability without degradation or colour fading. Direct replacement for ABS in outdoor applications.

Property	Value
Tensile strength	45 MPa
Flexural strength	78 MPa
Glass transition temperature	105°C
UV resistance	Excellent — no yellowing or degradation
Best for	Prolonged outdoor exposure, resisting UV degradation, and embrittlement where other engineering plastics fail.
Colour stability	High — retains colour under prolonged UV exposure
