The requirements for 3D-printed components are developing rapidly, according to Speedpart from Hasloch am Main. This is because the shape, level of detail and material properties of additively manufactured parts must be as close as possible to those of series parts. This is the only way to ensure that tests and functional prototypes are meaningful in terms of practical application. And with Accura Xtreme Black from 3D Systems, a new SLA resin is now available that meets precisely these requirements: It is robust, can be printed in true detail and it is jet black. This makes the material ideal for form, fit and function applications, says Speedpart. It impresses with its good durability for demanding assemblies, such as housings that have to withstand a lot.

Print Even Fine Details Reliably

With layer thicknesses from 0.002 in, even fine details can be reproduced, while wall thicknesses from 0.010 in and tolerances of ± 0.001 in guarantee reliable implementation of complex geometries. And even the basic finish produces a smooth and visually appealing surface. Blasting can be used to refine the component surface to a uniformly matt, anthracite-colored finish. For applications with particularly high visual requirements, a fine finish process is also available, which smoothes the visible areas in a targeted manner and achieves a high-quality appearance. In combination with the precise SLA technology, functional prototypes can therefore be printed that meet even the highest requirements. Speedpart was one of the first suppliers on the market to include Accura Xtreme Black in its portfolio.

The "Clear Edge" for 3D Printed Parts

Accura Xtreme Black complements Speedpart's portfolio of SLA materials, which also includes Accura Xtreme Grey and Accura Clearvue. It combines the robust mechanical performance of Grey with a deep black appearance that simulates realistic production components. The high-performance resin for prototypes is also suitable for components with snap-in functions or for consumer electronics components, notes Speedpart. In addition, master models for silicone or RTV molds can be printed efficiently. Its deep black color matches the aesthetics of injection-molded plastic parts while offering a cost-effective alternative to CNC-machined thermoplastics. According to the manufacturer, the low-viscosity formulation supports clean process control in the SLA process and helps to reliably mold sharp contours, clear edges and high dimensional accuracy—an advantage for development environments where quality and reproducibility are crucial.
