Consistent and efficient removal of support structures with an automated process

Innovative post processing of 3D printed components made from photopolymer resin

(PresseBox) (Staffelstein, )
Photopolymer resins allow the printing of extremely delicate high-precision components in industrial grade quality. The C1 system from AM Solution – 3D post processing technology is an excellent post processing tool for the automated removal of support structures. It meets not only the strictest industrial standards but also fulfills all requirements regarding process stability, consistency of the results, efficiency and traceability.

Photopolymer resins permit the high-quality printing of a large variety of precision functional components, design objects with extremely fine structures and the most complex prototypes. In the past the manufacturers had difficulties fulfilling the industrial standards for the post processing of 3D printed components. To date the removal of support structures was a manual operation. This is not only an expensive process that produces inconsistent results, but it also carries the risk of damaging the components.

A way out of this dilemma is the new C1 system from AM Solutions – 3D post processing technology. This division of the Rösler Oberflächentechnik GmbH specializes in offering automated industrial solutions for the post processing and surface finishing of 3D printed components. The compact plug-and-play machine, specially developed for the automated post processing of 3D printed photopolymer components, just needs a 230 V electrical outlet. The machine controls contain various processing programs that allow the support removal from components with different shapes. In addition, the users can tailor their processing programs to their specific needs. The C1 system can handle 3D printed components with sizes of up to 340 x 440 x 170 mm (L x W x H).

A precisely adapted compound ensures perfect post processing results

For the post processing operation the components are placed in a basket that in turn is dipped into an immersion bath filled with compound that is precisely adapted to the printing material. After the respective processing program has been called up, the process starts. This is based on chemical, thermal and mechanical effects. The effective interplay of these three mechanisms ensures that the support structures can be reliably removed without affecting the dimensional integrity of the components. This is even the case with extremely delicate components with geometrically complex shapes and very thin walls. Compared to other systems available in the market, this process is significantly faster.

For the development of the compounds AM Solutions – 3D post processing technology could take advantage of Rösler’s comprehensive know-how and the company’s chemical lab. With this approach suitable processing compounds could be developed for any photopolymer. Contrary to the extremely volatile and combustible isopropanol, usually used for this purpose, the compounds utilized by AM Solutions are not hazardous and must, therefore, not be classified and labeled as such per EG standard no1272/2008 (CLP).

Monitoring of the process parameters ensures stable and cost-efficient operations

The C1 system was equipped with various design features that guarantee process stability and minimize operational costs. This includes a sensor-controlled monitoring of the compound fill level: As soon as the level drops below a preset value, new compound is automatically replenished from a special container in the system. An integrated, removable skimming (overflow) screen allows the discharge of removed, gelatinous support material from the compound. This increases the usable life of the compound significantly. Moreover, an integrated sensor monitoring the degree of contamination signals when a compound exchange is needed. It ensures that such an exchange does not take place too early or too late. This saves costs and guarantees a consistently high processing quality.

Industry 4.0 - ready for the digital manufacturing environment

Like all post processing systems from AM Solutions – 3D post processing technology the C1 can be easily integrated into digitized manufacturing networks. Key process parameters such as temperature, processing time and the degree of contamination of the compound are continuously recorded with a data logger and can be stored through an USB interface. Industrial demands regarding quality control, process consistency and traceability can, therefore, be fully met for the post processing of 3D printed components.
