3DPrint.com Interviews’s CRP Group CEO Franco Cevolini https://ift.tt/2mRmrt9 The CRP Group is a large 3D printing service bureau in Modena Italy. The company was started in 1970 by Roberto Cevolini to make Formula 1 gearboxes and frames. In 1996 Roberto’s son Franco Cevolini decides to, only a few years after it was invented, look into 3D printing for racing and automotive. Specializing in powder bed fusion, investment casting, automotive parts and 3D printing services for racing teams CRP is unique in its deep involvement in car racing. Furthermore, the company is also unique because central to its success as a service is materials development. CRP’s Windform materials are high stiffness, high strength, high heat powder bed fusion materials that the company both uses to make car parts but also sells to other firms. Some of these materials have been designed to be post-processed by CNC or with high-stress fatigue or high surface quality in mind. Windform Glass fibre filled polyamides or carbon fibre filled polyamides have really brought powder bed fusion to the automotive world. I’ve been following the company for years to get a glimpse of interesting cases such as the bridge manufacturing of parts for Lamborghini using 3D printing or the design of high-performance intake manifolds. I was, therefore, more than honoured to get to interview CRP Group CEO Franco Cevolini about his firm. When did you get started making automotive parts? “We got started making automotive parts via Laser Sintering technology since the beginning of our activity in the world of professional 3D printing.” What kind of parts have you made? “We have made… all kind of parts! Some examples are: intake manifolds, inlets, air inlets, intake ducts, cockpit’s parts, alternator cooling covers, interior parts.” What makes powder bed fusion (also called SLS, Selective Laser Sintering or SLS) so suited as a technology for automotive parts? “SLS by itself it is not suited. But the combination of SLS technology and Windform composite materials makes SLS suited as a technology for automotive parts. This distinguishing feature is achieved thanks to mechanical features, durability and accuracy of Windform materials. Talking about the automotive sector, durability is the most important property. And… only Windform composite materials have it!” Do the SLS parts hold up long term?
What SLS materials are they made of?
Can you print parts for use in the engine bay? “Yes, of course! One of the most interesting examples that I can cite, it is the 3D printed Automotive intake manifold functional prototype we realized via SLS using reinforced carbon fibre composite material Windform® SP.” Can you give examples of saving weight with 3D Printed parts? “If we refer to supercars, it is possible to save weight with 3D printing by working on an optimized design. Otherwise, if we refer to “ordinary car”, mass-produced models, 3D printing is currently used to validate a project. Saving weight it is not really considered at the moment.” Why should companies look at 3D Printing automotive parts?
Do you see 3D Printing being used more in automotive? Yes, definitely. This trend’s happening in other advanced sectors as well: Aerospace, Defense and UAS. Printing via 3DPrint.com | The Voice of 3D Printing / Additive Manufacturing https://3dprint.com July 30, 2018 at 03:00AM
