FDR 3D Printing Service: The New Frontier of Micro-Precision

Powered by

High-Resolution Performance for Complex Systems

FDR technology bridges the gap between the speed of additive manufacturing and the intricate detail of micro-moulding. By focusing energy into a beam significantly smaller than standard SLS lasers, we can produce wall thicknesses and internal geometries that maintain the mechanical properties and structural integrity required at a microscopic level – while delivering a surface quality that rivals injection-molded components.

Industries benefiting from FDR:

  • Electrical and Electronical Equipment: Micro-connectors, intricate sensor housings, and miniaturized enclosures
  • Medical Technology: Micro-fluidic components and surgical tools
  • Aerospace & Defence: Lightweight, miniature actuators and sensors
  • Automotive: High-precision connectors for e-mobility and autonomous systems

Unlike standard polymers, the FDR process utilizes PA 1101, a bio-based polyamide. This material offers the high impact resistance and elongation at break required for functional living hinges and snap-fits, ensuring that even your smallest components have the mechanical properties needed to be rugged enough for end-use industrial applications.

As industries push for smaller, lighter, and more integrated devices, FDR provides the tool-less path to miniaturisation. We enable engineers to iterate rapidly on micro-scale functional prototypes and move directly into low volume production – and onward to serial production – without the multi-month lead times of micro-tooling.

While FDR ensures precision, Vapor Smoothing provides the finish needed for true functionality. By sealing PA 1101 without losing sharp details, it eliminates porosity and achieves an IP-rated, non-porous surface. The result is a surface quality with a professional, injection-molded look that significantly increases the fatigue life and durability of your micro-components.

Our FDR technology is centralized at our facility in Dornbirn, ensuring specialized process control. For medical applications requiring the highest regulatory standards, we offer production quality parts under ISO 13485 certification. This combines micron-level precision with the rigorous documentation and traceability essential for the global healthcare sector.

PA 1101

Engineered for micro-scale functional integrity, PA 1101 is a bio-based polyamide that offers exceptional impact resistance and the high elongation required for complex, moving assemblies.

How FDR Achieve Micron-Level Accuracy

The FDR process is a specialised evolution of Selective Laser Sintering (SLS), optimized for extreme detail:

The Step-by-step Process in FDR

  1. Digital Pre-Processing: Your CAD data is sliced at ultra-thin layer heights to capture every nuance of the geometry.
  2. Ultra-Fine Laser Sintering: A specialized CO laser, featuring a beam diameter significantly smaller than industrial standards, scans the powder bed of PA 1101.
  3. High-Resolution Fusion: Because the energy is so concentrated, the heat-affected zone is minimised, allowing for sharper corners, thinner walls (down to 0.22 mm), and intricate internal channels.
  4. Precision Cooling: Controlled thermal management ensures that the micro-features remain dimensionally stable and free from warping during the solidification phase.

FAQs

Do you have questions regarding Industrial 3D Printing? Find the most common questions and answers about the subject here.

Industrial 3D printing, also known as additive manufacturing, offers a wide range of advantages that have made it increasingly popular across various industries. Here are some key advantages of 3D printing:

  • Design Flexibility: 3D printing allows for intricate and complex designs that are difficult or impossible to achieve with traditional manufacturing methods. It offers design freedom, enabling the creation of geometries and structures that were previously impractical or cost-prohibitive.
  • Rapid Prototyping: 3D printing enables rapid prototyping, significantly reducing the time and cost involved in developing prototypes. It allows for quick iterations and design improvements, accelerating the product development cycle.
  • Cost Efficiency: Traditional manufacturing often involves high setup costs and tooling expenses. With 3D printing, these costs can be minimised or eliminated since it requires little to no tooling. It is particularly advantageous for low-volume production or customised/personalised manufacturing.
  • Reduced Waste: 3D printing is an additive process that minimises material wastage. It only uses the exact amount of material required for building the object, leading to more sustainable and environmentally friendly manufacturing.
  • Complex Geometry and Customisation: 3D printing enables the creation of complex geometries, intricate internal structures, and customisable designs. This is particularly beneficial for industries such as aerospace, healthcare, and architecture, where highly specialised and personalised products are required.
  • Supply Chain Optimisation: Additive manufacturing can decentralise production, allowing for on-demand manufacturing closer to the point of need. This can lead to reduced lead times, lower transportation costs, and optimised supply chains.

These advantages make Industrial 3D printing a valuable tool in various industries, including aerospace, automotive, healthcare, consumer goods, and more. By leveraging the benefits of 3D printing, businesses can gain a competitive edge, drive innovation, and unlock new possibilities in product development and manufacturing processes.
