FDM 3D Printing Bristol

Engineering Grade FDM Materials for Extreme Environments

Our extensive selection of industrial FDM materials is specifically chosen to meet the rigorous demands of defence and aerospace applications. Key materials include:

• ULTEM™ 9085: A high-performance thermoplastic with an exceptional strength-to-weight ratio, ideal for aerospace, automotive, and rail applications. It is FST-rated (Flame, Smoke, and Toxicity), offers excellent thermal and chemical resistance, and is lightweight and durable for functional prototypes and end-use parts. Certified-grade options ensure traceability for regulated industries.
• ULTEM™ 1010: Boasting the highest heat resistance of any FDM material (HDT of 216°C), ULTEM™ 1010 provides excellent chemical resistance and mechanical strength. Its autoclave compatibility makes it ideal for medical, aerospace, and food-grade applications, with certified grades available for biocompatibility and food contact.
• PEEK: This material offers exceptional mechanical strength and stiffness, comparable to metals, making it ideal for demanding engineering applications. With a continuous use temperature up to 260°C, excellent chemical resistance, and natural flame-retardancy, PEEK is perfect for engine components, aerospace fixtures, and medical implants.
• PEKK: Offering greater thermal stability and lower melt temperature than PEEK, PEKK provides superior layer adhesion for better isotropic mechanical properties. Its outstanding dimensional stability, low outgassing, and high resistance to wear, fatigue, and chemicals make it ideal for aerospace, satellite, and space-bound components.
• PPSU (Polyphenylsulfone): With higher impact strength and temperature resistance than PSU and PES (up to ~220°C), PPSU offers outstanding chemical resistance, even to aggressive disinfectants. Its high toughness and flame resistance are invaluable for aerospace, automotive, and healthcare applications, and it retains mechanical properties after repeated autoclave cycles.
• Nylon 12CF (Carbon-Fiber Filled Nylon 12): Carbon fiber reinforcement significantly increases stiffness, strength, and dimensional stability, offering an excellent strength-to-weight ratio. This makes it a lightweight alternative to metal for tooling and structural parts, providing best-in-class performance for load-bearing applications.

These materials, combined with our flexible nozzle options (0.2mm to 1.2mm) and high-temperature printing capabilities (up to 500°C), ensure we can produce parts with exceptional strength, thermal resistance, and chemical stability.

FDM in Defence & Aerospace: Strengthening Capabilities

Bristol’s defence and aerospace sectors are at the forefront of leveraging FDM 3D printing to produce robust, lightweight components with significantly reduced lead times. For critical applications where performance, rapid deployment, and adherence to stringent industry standards are paramount, FDM offers transformative advantages

• Functional Field Components & Lightweight Structural Elements: FDM enables the rapid production of durable components for tactical equipment, drone parts, and test rigs for defence, while in aerospace, it’s used for non-critical structural elements like brackets, ducts, and interior panels, often achieving substantial weight savings over traditional methods.
• Rapid Design Iteration & Prototyping: The ability to quickly print and test prototypes of weapon systems, communication devices, military vehicles, and aircraft components accelerates development cycles. This allows engineers to iterate designs quickly, assess form, fit, and function, and make informed decisions earlier, ensuring solutions are battlefield-ready faster and meet stringent aerospace specifications.
• On-Demand Manufacturing & Supply Chain Resilience: FDM supports the creation of custom parts on demand, reducing reliance on lengthy, vulnerable supply chains. This is critical for ensuring that mission-critical equipment remains operational in defence, even in remote or combat zones, and provides immediate availability for spare parts in aerospace, reducing aircraft downtime.
• Custom Tooling and Fixtures: Both sectors benefit from FDM’s ability to produce highly specific manufacturing aids. This includes inspection fixtures, drill jigs, masking templates, and composite mold tooling, which can be rapidly produced to reduce manufacturing costs and accelerate assembly processes.
• Complex Geometries and Part Consolidation: FDM offers unparalleled design freedom, allowing for intricate designs and the consolidation of multiple parts into a single component. This not only reduces weight and assembly time but also enhances performance by enabling features impossible with traditional manufacturing methods.
• Flame-Retardant and High-Performance Materials: The availability of advanced thermoplastics like ULTEM™ 9085 and PEKK, which offer high strength-to-weight ratios, excellent thermal and chemical resistance, and flame, smoke, and toxicity (FST) ratings, is crucial for producing flight-approved parts and components for demanding defence environments.
