No need for drawings.

We have a team of processing engineers and design professionals who can create 3D models and accept 3D data, so you don’t need to have any drawings. We also handle STL data (large volume data used for design data).

Even if it would normally take a huge amount of time to process, we can achieve a quick turnaround with an optimized process.

Quality of data

Thorough quality control

We have a thorough quality assurance system based on ISO 9001, the international standard for quality assurance. Under our own strict control system, we aim to achieve zero defects by making full use of the latest measuring instruments and equipment, including 3D measurement devices.
