AM Solutions, the AM brand of Rösler, has worked with Mimaki on the development of a post-processing solution for its full-colour inkjet 3D printer, the 3DUJ-2207. The latter has been unveiled last year; it is the second machine the colour 3D printing specialist added to its portfolio of 3D printing solutions.
The solution that was described as an important step forward for detailing and post-processing, features a build size of 203 x 203 x 76 mm and can operate with over 10 million colours at the production level.
To make this step forward for detailing and post-processing real, the 3D printer manufacturer decided to collaborate with post-processing expert AM Solutions.
“With AM Solutions and Rösler, we have a partner with extensive know-how and experience in the fields of mechanical engineering, industrial surface finishing, and the development and production of consumables. At the same time, the company is among the leading suppliers of automatized post processing equipment in the AM sector, where it pursues constant development”, explains Arjen Evertse, General Manager Sales from Mimaki.
At the heart of their collaboration, is an Industry 4.0-ready plug-and-play system whose matching compound is classified as not hazardous to water and with high flash point.
The new machine has been built while taking into account all the required safety measures, such as a regular 230 V electricity supply, special caster wheels for the easy repositioning of the machine, and a web interface to facilitate operation and monitoring via smartphone.
How does the machine work in practice?
Depending on the type of parts they will manufacture (big parts, complex parts with support structures, etc.), operators will have to choose between different programs to control the machine.
It goes without saying that, each configuration could be saved for future utilizations. When the process starts, chemical, mechanical, and thermal effects interact according to the parameters selected specifically for the program.
A press release explains that this interaction ensures that the support material is completely removed in a way that is gentle on the printed part and at the same time effective and fast. One crucial advantage of the significantly 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.
