Hohenstein: digital material libraries with physical sample books will accelerate 3D design


BÖNNIGHEIM, Germany – March 4, 2021 – Textile Testing Partner Hohenstein will now help 3D designers and fabric suppliers create libraries of accurately scanned materials with a physical sample book. The material parameters, based on Hohenstein’s universal translator approach, include the data necessary for consistent simulation across all digital design platforms. The optional color swatch, which specifies the inputs for specific platforms, allows designers to see and feel the fabric swatches they are using.

“The precise parameters of digital materials are often overlooked, but have a huge impact on realistic simulation and fit,” said Simone Morlock, manager of Hohenstein’s digital fit lab. “We also recognize the value of getting our hands on the hardware. Even though the process is digital, these products are still designed by – and for – humans. “

The new service addresses challenges caused by the lack of standardization, where each 3D program requires different parameters, uses different names and units, and recommends different test kits. Hohenstein’s universal translator approach was developed during an internal research project aimed at standardizing the digitization of materials. He analyzed the different requirements, data formats, units and results of different 3D garment design systems. After reducing the test parameters to five essential textile-physical tests, the lab created a conversion that ensures consistent visualization and behavior across different systems.

Accurate digital material parameters are the key to the successful use of 3D technologies for visualization and fit technical prototyping. Designers will have access to digitized materials that exactly match the fabrics they have chosen. Color charts can be customized by brands or suppliers to match specific collections. With the increasing adoption of digital design, suppliers are under pressure to make their fabrics available in all digital formats. For vendors who want to reach these digital designers, it will be crucial to ensure that their fabric is accurately represented, regardless of the platform the client is using.

In laboratory procedures specially adapted for 3D simulation, Hohenstein experts determine the physical characteristics of the material: weight, thickness, flexural stiffness, elongation and volume and fold shape. The results are exported in the various file formats of the 3D simulation systems so that the digital material parameters are available in the appropriate file format for each customer. Upon request, Hohenstein can include texture data and 3D fabric images for visualization of specific drape behavior.

With consistent data, digital prototypes can be created that speed up the design, procurement, and approval processes and require significantly less material when making actual samples for production. As an accredited laboratory for comprehensive textile testing, Hohenstein combines many years of expertise in the development of traditional clothing fits with digital technologies. In addition, the Hohenstein Academy offers many workshops on model development and 3D fitting.
