Delicate Structures
Highest 3D printing precision with Fine Detail Resolution (FDR)
1zu1scale has had EOS's innovative system in its portfolio as a pilot partner since 2021 and uses it to produce 3D-printed components with impressive precision: components measuring 5 to 40 millimeters with high detail resolution, temperature resistance, and elongation at break – with minimum wall thicknesses of 0.22 millimeters. Whether tiny holes, channels, undercuts, or grids: FDR reproduces details with 40 micrometers (= 0.00004 meters) dimensional accuracy.
The miniature components are even ready for series production. They undergo automated post-processing at 1zu1scale, meet all quality criteria, and can be chemically smoothed and colored without any loss of dimensions.
Precision Laser for fingernail-sized Components
With FDR technology, a very fine laser beam combined with the particularly tough yet flexible material polyamide 11 (PA1101) creates sharp edges with an accuracy of four hundredths of a millimeter. The bio-based material (castor beans!) also scores highly with strong properties such as high UV, chemical, and temperature resistance (up to 200 degrees Celsius), tensile strength (48 MPa), and elongation at break (up to 40 percent). This opens up new areas of application: in addition to fully functional prototypes, 3D printing can be used to produce series parts such as filter units, sieves, fluid guides, hinges, and electronic connectors.
Chemically smoothed, FDR components hardly differ from injection-molded parts. Added to this are speed and design flexibility. The components are delivered to the customer in three days instead of three months – without tooling costs. From 1 to 1,000 pieces, the use of 3D printing technology is economically viable. For customizable products and components specially designed for FDR, larger quantities are also profitable.
Stable, fast, and secure
FDR combines the best of both worlds: the components are as fine as in stereolithography (SLA) and at the same time as stable and durable as in selective laser sintering (SLS). Small, precise parts for series applications place high demands on quality assurance. 1zu1scale relies on computed tomography (CT) for this purpose. This innovative measurement method also makes internal geometries such as channels or compressed air chambers visible.
