Everything from one sourceAll-round service at 1zu1

3D printing, vacuum and syringe casting are our specialties at 1zu1. But we also cover the all-around in house and process the raw parts from the machines into market-ready series products or fully functional prototypes.

As a full-range supplier and service partner, we always think of the big picture and have the full product life cycle in mind. With our mechanical production center, numerous surface technologies and state-of-the-art testing and measuring equipment, we support our customers along the entire production chain right through to quality control and, if desired, can also take over the assembly of components. In this way, we create the basis for the rapid, high-quality and efficient implementation of your projects.

Mechanical expertise

We manufacture tools, construction and testing gauges as well as small quantities of precise metal and plastic components ourselves. For milling and turning, we rely on state-of-the-art CNC machines and industrial robots and process aluminum, copper, brass, bronze, steel and numerous types of plastic. Our broad expertise pays off, for example, in injection molding production. Tooling usually requires repeated minimal adjustments of tolerances, wall thicknesses or other details until perfection is achieved. In-house mechanical production means that we are always able to make changes and corrections quickly and flexibly. This creates independence, saves time and costs, such as with the twelve quickly developed series tools for the medical technology company Artivion.

Fine tuning and individualization

Precision, appearance and functionality: few components are ready for use after production and 3D printed parts are simply white in the first step. Whether in 3D printing, vacuum or injection molding: depending on the requirement and use, all elements at 1zu1 are subsequently refined to perfection using various processes. Some like it colored, need smooth, dense, glossy, sandy rough or textured surfaces and imprint their brand on the parts with labels, foils or stamps. At 1zu1, we have an in-house solution for almost every need.

White 3D printed plastic parts can be colored in any desired color without dimensional loss via hot print impregnation. We paint, polish, engrave, infiltrate, trovalize and vaporize components. We add an individual touch with various printing techniques, laser marking and hot foil stamping. For 3D printed components, we provide several advantages with the innovative chemical smoothing process. Smoothing also increases the sealing properties, as in the case of the air distributor for STORZ MEDICAL.

In vacuum casting, mechanical finishing is one of the central quality criteria. The elements, which are ready for series production, are ground and polished, painted and printed by hand at 1zu1 until they fit precisely. What this can look like in practice can be seen, for example, in the shiny housing for the NanoTemper or the two visible components for the MAGNETOLITH from STORZ MEDICAL.
