15 industrial and tutorial partners appear collectively for “breakthrough” POLYLINE challenge


The 4th of Might saw the start of the POLYLINE venture, a lighthouse project that will deliver collectively 15 industrial and analysis associates from throughout Germany to establish a digitalized AM manufacturing line. The automatic generation line will target on 3D printing certification serial polymer components for the automotive sector. By complementing traditional production methods with industrial-grade AM technological know-how, the companions hope to create a range of large-throughput production line devices to progress automotive producing.

POLYLINE has obtained a whole of 10.7M in funding from the German Federal Ministry of Instruction and Analysis. It will consider location in excess of the course of 3 yrs and was commenced at a kick-off meeting at EOS, who is major the undertaking, in Krailling, Germany.

The POLYLINE venture

The design and style flexibility granted by additive production certification technological innovation makes it excellent for highly sophisticated bespoke prototyping. As it stands, nevertheless, the vertical and horizontal integration of AM into existing industrial production strains is generally tough due to a absence of requirements. The criteria are not in spot because of to the relative infancy of AM-certain workflows and processes this kind of as write-up-processing and portion transport. Quite a few of these procedures are however really handbook – an concern the POLYLINE task aims to solution.

On the digital aspect of things, there is a absence of transparency, a proneness to faults, and restricted process chain monitoring capabilities as a outcome of a deficiency of interface continuity in the horizontal digital knowledge chain. The challenge partners think these hurdles seriously limit the likely of AM in existing sequence output lines.

Scalable AM generation strains

To take into consideration the job productive, the companions will have to create a “breakthrough” procedure masking both of those the digital and actual physical areas of manufacturing. They will document and preserve a document of all central traits and high-quality criteria from the CAD style to the last actual physical aspect. All unique sub-processes (preparation, SLS, cooling, unpacking, cleansing, and publish-processing) will be automatic and combine into the manufacturing line. According to EOS, this will be the to start with time all the person elements of an SLS manufacturing line will be joined with each other in 1 steady automated chain.

The hopes are that the holistic method of the undertaking will be capable of utilizing the prepared creation line with a high diploma of maturity in line with the apps it will be utilized for. In accordance to EOS, the use circumstances address particular person bespoke areas as nicely as serial parts in bigger quantities.

The entire list of project companions is as follows: EOS, BMW Group, Grenzebach Maschinenbau, 3YOURMIND, Additive Marking, DyeMansion, Bernd Olschner, Optris, Krumm-tec, Paderborn University, Fraunhofer IGCV, Fraunhofer IML, Dortmund College of Technologies, University of Augsburg, and College Duisburg Essen.

The challenge of AM benchmarks is a very long-standing 1 which the POLYLINE project aims to resolve – at the very least for automotive. Earlier this yr, a amount of business leaders gathered in Munich for the 2nd TÜV SÜD Additive Producing certification Convention to explore the implementation of industrial additive producing certification via standardization and digitization. Much more recently, AMT and Leering Hengelo partnered up to launch two new automatic de-powdering programs for 3D printed elements. Even though it does not address the overall procedure chain, the PostProDP selection aims to automate the excruciatingly tiresome and guide put up-processing associated with PBF parts.

The nominations for the 2020 3D Printing certification Business Awards are now open. Who do you consider really should make the shortlists for this year’s display? Have your say now.
