The German company's realization of rapid prototyping VG Kunststofftechnik notes a great potential in the direct manufacture from Stereolithography (SL), especially with the recent availability of the next generation of materials for SL, as we are NanoForm 15120.

Marketed by DSM Somos since November 2004, NanoForm 15120 is a material composed for the Stereolithography that incorporates no crystalline nanoparticles technology to improve its performance properties, including a high rigidity and resistance to temperature. It has been reported on temperature of deformation by heat of more than 265 ° C.

VG began by making direct with NanoForm manufacture as it sold, and used it in their Systems Viper B4 3D machine. Its first application was made in small parts with much detail for the electronics, aerospace and medicine, as well as to specialists such as Hansa or Grohe water technology. Today, after having tried since the properties of this resin and its excellent profitability, VG usually produces up to 200 pieces using the direct manufacture from NanoForm for preserial and short production series.

"NanoForm offers a unique set of critical properties for direct manufacturing," says founder and CEO of VG, Volker Griessbach. "Its accuracy, hidroscopicidad zero and excellent surface quality - virtually no effects of"step"2 - provide the high level of accuracy and detail that the electronics industry, in particular, needs, and to guarantee the dimensional stability of the parts." In addition, NanoForm presents a high resistance to water and can withstand temperatures up to 250 ° c. "This is added to a number of critical advantages to the extensive evidence of our clients in the preserial."

As well as allowing the production of parts with a high level of geometric complexity and precision (dimensions of walls and usual drill holes as small as 0.2 mm) to VG, the direct manufacture with NanoForm has also demonstrated success to avoid some of the delays and costs associated with the processes of construction of moulds.

In a test of invierno-verano of the car to Siemens industry, VG Kunststofftechnik could successfully produce 1,000 electromagnetic coils with NanoForm in just one week, which could be immediately assembled and finished. Using NanoForm (in the realization of the mold) Siemens could save about 40,000 euros in costs for molds and could also cut its testing programme in four months to plan.

"I believe that the direct production will go down in history as the third industrial revolution", says Griessbach. "It is a more proven method for industry, that shortens development cycles and responds to the growing demand for pieces of series short and made tailored to the customer." "To VG, the combination of the correct technologies with new materials effective as NanoForm has worked in becoming pioneers in direct manufacturing - work in carrying out rapid prototyping for over fifteen years."
