Knaus Tabbert AG bets on the post processing solution S1 from AM Solutions – 3D post processing technology
Absolutely clean 3D printed components for recreational vehicles with a fully automatic operation
A significant quality improvement of the de-powdering and cleaning operation for 3D printed components at lower costs and shorter cycle times ! A leading manufacturer of recreational vehicles is fulfilling this goal with the purchase of the automated post processing system S1 from AM Solutions – 3D post processing technology .
With their innovative designs and powerful drive systems the motor homes , caravans and panel trucks of the Knaus Tabbert AG allow safe , comfortable and sustainable travelling . At its German headquarters in Jandelsbrunn , Bavaria , the company is utilizing its comprehensive experience and knowhow to continuously improve the materials and designs of its vehicles .
Naturally , this also includes the employment of new manufacturing technologies such as additive manufacturing ( AM ). Mario Meszaros , development engineer at Knaus Tabbert explains : “ On the one hand we are using the 3D printing technology for creating prototypes . On the other hand we are also utilizing additive manufacturing for producing standard components in volume such as the bracket for an alarm system or the hinge mechanism for the swing-out shower stall ”.
A challenging post processing task
To date the de-powdering and cleaning of PA 12 components , produced by a powder-bed printing system , was done manually in a blast cabinet . Since this post processing operation required not only a lot of labor and time but also produced highly erratic and inconsistent results , the company was looking for an automated alternative .
Therefore , comprehensive processing trials were run with different components in the Customer Experience Center of AM Solutions – 3D post processing technology . This division of the Rösler group specializes in post processing solutions for 3D printed components . After conclusion of the highly successful processing trials the customer chose the S1 shot blasting system .
This shot blast machine was specifically developed for the post processing of plastic components produced with the powder bed printing method . The plug and play S1 is the only machine on the market that allows the time-saving and cost-efficient de-powdering as well as surface smoothing and homogenization of 3D printed components in one single machine . All that is required , is a simple change of the blast media , for example , from glass beads to plastic spheres .

On the other hand , this technology is also used to produce series components , such as a bracket for an alarm system or the hinge mechanism of the swing-out shower cabin . An S1 system from AM Solutions - 3D post processing technology is utilized for the post processing .
