Corresponds to ultra-fine shapes of around 0.2μm. For medical device parts, microneedles, micro lenses, etc.
"Prototyping of ultra-fine parts using the world's highest precision 3D light sculpting technology" This is a manufacturing contract service for micro lenses, diffractive optical elements, micro needles, MEMS, etc., using the world's highest precision 3D light sculpting technology, the "Nanoscribe System." It is being advanced in collaboration with Kyoto University of Advanced Science. By utilizing 3D printing technology based on two-photon polymerization and IP resin with sub-micron resolution, this system enables the production of shapes and precision that are impossible with conventional methods. The image at the top shows a battleship Yamato-sized object that can rest on a strand of hair. No molds or cutting are required, and we can accommodate prototyping from a single piece. By applying dry plating (gold, platinum), it is also possible to impart conductivity. We can meet delivery times within three weeks. We can also create designs if 3D data is not available. The applicable sizes vary by material, but the minimum shape dimensions are XY: 0.2μm, Z: 0.3μm. The maximum build height is 8mm. This technology is utilized in research and industrial fields such as mechatronics, biotechnology, microelectronics, optics, medicine, and materials engineering. If you are considering prototyping ultra-fine parts, please feel free to contact us.

Company information
With a posture of "just half a step" without complacency, we have cultivated "lost wax precision casting" over many years. Utilizing 3D printing technology, we offer next-generation precision casting technology called "Digital Cast." We obtained a U.S. patent for "MIM (Metal Injection Molding)" in 1991. We provide optimal proposals using various technologies and thoroughly support our customers' manufacturing! We specialize in complex three-dimensional shapes in small lots of various types and carry out everything from mold making to casting, machining, and simple assembly in an integrated in-house system. We supply products to various industries, including medical devices, semiconductors, machine tools, and aerospace. "Just make it, from one piece." We can propose a wide range of manufacturing methods from prototype production of one piece to mass production. We also enable time savings in searching for various suppliers and considering consultation destinations, becoming a true total cost reduction partner by proposing reductions in management costs related to consideration time and product costs. More than half a century ago, Castem began its casting business by handcrafting machine tools. Today, we have become a leading company in Japan for manufacturing general industrial components using lost wax casting and are also engaged in the production of micro lenses and micro needles using the world's highest precision 3D light shaping technology.
