3DXTech Specialty & Flexible Filament
The materials that don’t fit a single category — 3DXTech’s flexible, flame-retardant and specialty filaments. 3DXFlex TPU and PEBA elastomers for flexible and high-rebound parts; FluorX PVDF for chemical and UV resistance; flame-retardant FR-ABS, FR-Nylon and FR-PC for safety-critical parts; SimuBone for medical bone models; AquaTek PVA and LTS2 for dissolvable and break-away supports; and glitter/satin PLA for finish. This page groups them so you can find the right specialty material fast.

Choosing a 3DXTech specialty & flexible machine
The decisions that actually matter for this class of machine — size them to your parts, not to a spec sheet.
How flexible?
Shore hardness sets the feel: 3DXFlex TPU 85A is soft and very elastic (gaskets, grips), TPU 95A is semi-flexible and easier to print (tougher flexible parts), and PEBA 90A is a lightweight, high-rebound elastomer for dynamic and sporting parts.
Flame-retardant choices
For safety-critical parts choose by base polymer: FireWire FR-ABS for general enclosures, Obsidian FR-Nylon for tough mechanical parts, and 3DXLABS FR-PC for high-heat, high-impact flame-retardant applications.
Chemical & specialty
FluorX PVDF resists aggressive chemicals, UV and weathering for fluid-handling and outdoor parts; SimuBone mimics the look and feel of bone for surgical models and training.
Supports & finish
For complex geometry pair your model material with AquaTek PVA (water-soluble) or LTS2 (break-away). For looks, glitter and satin PLA add finish without special hardware.

Frequently asked questions
Which flexible filament should I choose?
Pick by hardness and feel: 3DXFlex TPU 85A is soft and very elastic for gaskets, seals and grips; TPU 95A is firmer, tougher and easier to print; and PEBA 90A is a lightweight, high-rebound elastomer for sporting and dynamic parts.
What flame-retardant options do you have?
FireWire FR-ABS for general enclosures, Obsidian FR-Nylon for tough mechanical parts, and 3DXLABS FR-PC for high-heat, high-impact flame-retardant applications — all for safety-critical electrical and transit parts.
What is FluorX PVDF used for?
PVDF is a fluoropolymer with outstanding resistance to aggressive chemicals, UV and weathering — used for fluid-handling, chemical-process, semiconductor and outdoor parts where other plastics would degrade.
PVA or LTS2 for supports?
AquaTek PVA dissolves in water for clean removal from complex internal geometry; 3DXMAX LTS2 is a break-away support you snap off by hand. Choose PVA for intricate internal channels, LTS2 for simpler overhangs and faster processing.
Are these made in the US and in stock?
Yes — 3DXTech specialty and flexible filaments are made in the USA and ship from US stock. Rev1 is an authorized 3DXTech reseller with US-based support. Call (248) 707-2950.
