AM solutions offers a compact post processing system for the full-color inkjet 3D printer, the Mimaki 3DUJ-2207. This post processing system automatically removes support structures without compromising the high level of detail and color nuance of the 3D parts. It also speeds up post processing up to three times faster than with equipment previously available on the market.
The 3DUJ-2207is a compact and affordable 3D printer with a build size of 203 x 203 x 76 mm and offers more than 10 million colors. Usually, the solutions for the removal of support structures are treating the work piece with wet blasting or water bath. However, each of these processes involves the risk of damaging the filigree 3D parts.
Mimaki chose to cooperate with AM Solutions, a division of the Rösler Group, to develop a post processing system consisting of an Industry 4.0-ready plug-and-play system. The system contains all the necessary safety features, making a regular 230 V electricity supply the only requirement for operation.
The system is equipped with a web interface enabling operation and monitoring via smartphone. For the fully automatic removal of the support structures, the 3D parts are placed in the immersion bath of the system followed up by selecting the fitting processing parameters. For this purpose, there are already different programs available in the equipment controls by default, covering a range from bigger parts with many support structures to very delicate printing objects. In addition to that, users can configure programs for their 3D parts themselves and save them in the equipment controls.
The process then starts with chemical, mechanical, and thermal effects interacting according to the parameters selected for the program. This interaction ensures that the support material is completely removed in a way that is gentle on the component and at the same time effective and fast.
Initial tests have shown that support removal is up to three times faster than other systems on the market. One crucial advantage of the shorter processing time is that it prevents the work pieces from swelling in the bath. At the same time, the relatively low bath temperature also avoids damages. This is ensured by an integrated monitoring, which automatically shuts down the system if the temperature is too high.
After a defined processing time, the basket is removed from the immersion bath, with the dripping compound being collected and returned to the dip tank. Due to the classification as non-water hazardous, the parts can simply be rinsed under running water before the next step. Furthermore, you can place the container you used to fill in the compound under the drain valve of the dip tank what allows for an easy and quick compound change.
