In 2011 BAM GmbH was founded by the current managing director Marco Bauer in Weiden in the Oberpfalz. Starting as a classic contract manufacturer with eight employees, it is now a multi-award-winning digital company.<\/span><\/p>\nBAM GmbH offers precision manufacturing, special machine construction and digital services. In the field of additive manufacturing, BAM relies on the Metal X metal 3D printer system and the Mark Two carbon fiber 3D printer from Markforged, among other technologies.<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div>

The Challenge<\/span><\/h2><\/div>Many possible applications in the service sector<\/strong><\/span>
\nBAM GmbH offers a wide range of products for the manufacture of metal and plastic components of the highest quality and with the narrowest tolerances for numerous different industries. For these applications, additive manufacturing is the best choice, especially in the field of weight optimisation.<\/span><\/p>\nUp to now, most parts have been manufactured by machining, which is complex and cost-intensive, especially in prototyping. Managing Director Marco Bauer also prints individual parts for his own state-of-the-art machinery.<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>
Implementation<\/span><\/h2><\/div>Easy entry into Additive Manufacturing due to the closed overall system<\/span><\/strong>
\nWhile searching for a metal 3D printer, founder and managing director Marco Bauer got to know the production technology of Markforged. He was particularly convinced by the easy handling of the material change by simply replacing the material rolls.<\/span><\/p>\nMarkforged\u2018s all-in-one system connects all components with each other: from the cloud-based software to the 3D printer and the post-process (washing and sintering). This gives a quick and easy overview of the complete process chain. The individual components are matched to each part accordingly, so that the best possible result can be achieved from the very first print! Thanks to the cloud-based software, print jobs can even be started conveniently from on the road.<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div>

The Solution<\/span><\/h2><\/div>Design freedom for component optimization<\/strong><\/span>
\nDue to the additive manufacturing there are almost no restrictions in the geometric complexity of a component. This is advantageous for making components lighter and optimizing them for their intended use.<\/span><\/p>\nBy processing continuous fibres, the components are given more performance in terms of strength with an excellent surface quality.<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>

Edging Tool<\/span><\/h2><\/div>Simple production of functional prototypes<\/strong><\/span>
\nMarco Bauer shows the use of the Markforged Metal X on an A2 tool steel edging tool. After the design, an STL file of the part is created to be imported into the EIGER software. There the tool can be prepared for printing (wall thickness, internal structure etc.). Afterwards the printing can be started with a simple click!<\/span><\/p>\nThanks to a honeycomb structure inside the component, weight can already be saved with the same geometry and stability. After printing, the washing and sintering processes follow, whose optimum temperatures and times for the component are calculated by the EIGER software and sent to the machines. So here too the postprocess can be started with a simple click. The component is ready for use immediately after sintering. For an even better surface quality or lower tolerances the component can be polished, ground or CNC reworked.<\/span><\/p>\n<\/div>Data of the edging tool:<\/strong><\/span>

\nMaterial costs:<\/strong> 150 \u20ac<\/span><\/p>\n<\/div>The advantages of 3D printing compared to CNC production can be seen in this component:<\/span>
\nIncreasing the complexity of a component leads to additional costs and longer delivery times in machining production. In additive manufacturing, weight-reducing measures lead to cost reduction and the generation of added value.<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>
