AM Solutions Automates Smoothing and Homogenization for Printing Job Shop

Leave a comment

When Klaus Stöcker (Stöcker) started offering ready-to-install 3D-printed plastic and metal components to its customers, the job shop initially utilized manual post-processing methods. Due to the rapidly growing demand and stricter requirements for process stability and consistency of these operations, the company took a new approach when it purchased two automated systems from AM Solutions, a brand of the Rosler Group.

The initial purchase included an S1 for de-powdering and an M1 Basic for surface smoothing and homogenization. Based on excellent processing results, a second M1 Basic system was recently commissioned as a cost-efficient alternative to chemical smoothing.

The Situation

Klaus Stöcker metal processing was founded in 1990 in Wermelskirchen-Dabringhausen, Germany. Since then, it has grown to employ approximately 60 team members and offers a wide range of services in the field of machining. This includes turning, milling, sinking and wire EDM, face and circular grinding, assembly, and measuring with state-of-the-art machinery.

Growing utilization of additive manufacturing for volume production of plastic components has increased the demand for cost-efficiency and high-quality surface finishes. That’s why AM Solutions, a brand of the Rosler Group, has further expanded its product portfolio with the development of a media type specifically for the post processing of plastic components.

Designed specifically for work pieces printed with MJF and SLS powder-bed-based technology, AM Solutions’ media permits the safe, cost-efficient finishing of 3D printed components with different shapes and sizes in one single process step and with absolutely repeatable results. This eliminates the time-consuming and costly media changes for different processing stages.

In combination with an understanding of respective printing processes, the media mix generates a perfect, finely structured, and highly homogeneous surface finish.

AM Solutions Delivers Post-Processing Solutions for Prototypes & Parts

Leave a comment

Knaus Tabbert AG is a leading manufacturer of recreational vehicles. The company’s innovative designs and powerful drive systems for motor homes, caravans, and panel trucks allow for safe, comfortable, and sustainable travel.

At its German headquarters in Jandelsbrunn, Bavaria, Knaus Tabbert utilizes its comprehensive experience and know-how to continuously improve the materials and designs of its vehicles as well as new manufacturing technologies such as additive manufacturing.

Seeking faster and less expensive post processing for its 3D printed prototypes, Knaus Tabbert turned to AM Solutions, a brand of The Rosler Group, to find a better way.

Challenging Post-Processing

From prototyping to production, Knaus Tabbert needed de-powdering and cleaning operations for additively manufactured work pieces.

“On the one hand, we are using 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,” said Mario Meszaros, Knaus Tabbert Development Engineer.

Orthopedic Implants, Part 4 – Finishers Meet Standards, Face New Challenges

6 Comments

While choosing the right implant material is of utmost importance, as discussed in our previous Orthopedic Implant Series post, the significance of optimum surface treatment throughout the entire implant manufacturing process cannot be overstated. This relates not only to the right surface finish, but also total compliance with the specified tight dimensional tolerances.

The functionality of an orthopedic implant is determined by the perfect match between the various implant components. This depends, to a large extent, on the surface treatment procedure(s).

With extensive experience in the medical industry, Rosler is an expert in designing systems and solutions for the treatment of joint reconstruction implants utilizing shot blasting and mass finishing technologies.

Our Orthopedic Implant Series continues with an overview of the stringent finishing standards for orthopedic implants.

Shot Blasting, Peening Offer Aerospace Advantages

Leave a comment

Critical aerospace components require first-class surface treatment. From engines, fuselage, wings, and landing gear to seats, gears, propellers, blades, fasteners and tanks for fuel, water, and waste, Rosler has industry experience and expertise.

While mass finishing and shot blasting methods are equally useful to manufacturers of new components and in the overhaul and repair of existing components, shot peening – a particular type of shot blasting – is especially advantageous for aerospace work pieces thanks to its ability to provide surface finishing and create internal compressive stress for improved component life.

Shot Blasting Capabilities

Rosler’s shot blasting technology meets the strict surface finishing requirements predicated by tight tolerances for safety and longevity. This impact-based process propels small metal or mineral pellets onto a work surface at speeds of 200-800 feet per second.

Desired finishes including cleaning, texturing, removal of or preparation for coating, and peening can be pinpointed to specific areas of a given work piece as well as the entirety of large, structural components.

Joint Reconstruction, Part 3 – Surface Finishing Standards

4 Comments

While choosing the right implant material is of utmost importance, as discussed in our previous Joint Reconstruction Series post, the significance of optimum surface treatment throughout the entire implant manufacturing process cannot be overstated.

This relates not only to the right surface finish – be it a high-gloss polish for low friction, a textured surface for easy osseointegration, or as preparation for subsequent coating, rounded edges, etc. – but also total compliance with the specified tight dimensional tolerances. The success of a joint implant is determined by the perfect match between the various implant components. This depends, to a large extent, on the surface treatment procedure(s).

Advanced composite and metal additive manufacturing components require final surface finishing.

Whenever the surface of aerospace, automotive, creative, dental, industrial tooling, medical and moulding tools are produced with additive manufacturing the surface requires to be improved.

Additive manufacturing, the creation of 3-D solid objects by using a series of layered materials, allows the production of complex individual components from various materials such as plastic, nickel alloys, titanium, stainless steel and precious metals.

It permits the creation of shapes and geometries which are not possible with any other production method. However, the surface finish of parts created with additive manufacturing frequently requires final finishing.

The adaptation to particular work piece shapes and surface requirements can be achieved by the development of tailor-made finishing solutions.

Equipment and process methods for either the intensive or very gentle surface smoothing of such components are available according to their component substrate and design geometry.
