With our cutting edge stereolithography technology, CMET supports any needs for product developments.

In the conventional lost wax investment casting, a mold is first prepared to make wax patterns before the actual casting can be done. With stereolithographic investment casting, the wax patterns are created by stereolithography without using a master die.

Cast models created without molds

Conventional investment casting by lost wax process always requires a mold to create wax patterns. This results in problems such as cost inefficiency in small lot production or extended delivery lead time due to extra mold creation.
In stereolithographic investment casting, the wax pattern is made by stereolithography instead of the master die, so all these problems are solved.

Especially for when a really small amount of casting is needed, such as for prototype making at the early stages of development and small-lot production, both the lead time and the cost is cut down and a quick service will be possible.

Improved resin with low ash creation and high incineration speed makes casting easier

When heated, wax melts but resin gasifies and disperses. However, the problem with conventional resin is that a great amount of incineration ash remains inside the mold, deteriorating the surface of the casted product.
With our new antimony-free resin, we have succeeded in cutting down this incineration ash. As a result, the appearance of the casted model is improved greatly.

High precision and reproductivity only possible by streolithography reflec ted in the finished product

Stereolithographic investment casting is the best way among the numerous additive manufacturing technologies to faithfully reflect the high precision and the high quality appearance of stereolithography to the casted product. In powder-layered manufacturing, the unevenness of the surface of the model results in an uneven surface in the cast, and the finishing process takes time. Stereolithographic casting solves this problem, and furthermore, allows a high precision unachievable by 3D printers. Creation of a very thin object is possible, too.
Especially the turbo impeller and the inverter case shown in the pictures are representative application examples. Stereolithographic casting solves all the problems otherwise held if the model was created by 3D printer, powder-layered manufacturing, or cutting works. This case clearly shows the advantages of the stereolithographic casting.
