Crispin Orthotics Purchases HP 4200 from Europac 3D for 3D Printing Orthotic Devices

In 2016, 3D printing, scanning, and inspection business Europac 3D, headquartered in the UK, was named a UK Channel Partner for HP, which means that it’s responsible for the sales and servicing of all of HP’s 3D printing equipment in the country. Recently, Crispin Orthotics contacted Europac 3D in search of a new 3D printing and CAD software package that would be able to keep up with the demand for orthotic devices, while also speeding up production and lowering 3D printing costs, and the company suggested HP’s 4200 Multi Jet Fusion 3D printer for the job.

“The HP Multi Jet Fusion 4200 is able to accurately mass produce bespoke orthotic devices, which in turn can cut costs and speed up production times,” said John Beckett, the Managing Director and Founder of Europac 3D. “Crispin Orthotic’s use of the HP’s Multi Jet Fusion printer is indicative of how additive manufacturing is revolutionising the orthotics industry.”

Crispin is a top HCPC registered clinic specializing in producing and maintaining orthotic devices, and has already worked with HP in the past. By making a further investment in its MJF technology, Crispin is able to produce parts that are strong and flexible enough to be made into orthotics that can endure a human’s everyday movements.

HP’s 4200 MJF can produce parts up to ten times faster, and at a 50% cost-per-part reduction, when compared to other SLS 3D printing systems. This reduced cost and increased speed means that Crispin will be able to 3D print hundreds of personal, customized orthotics in just 12 hours.

Crispin tested out its new HP 3D printer by pairing it with Siemens NX CAD software, featuring topology optimization, so its technicians could add strength to important areas and make designs more lightweight. In addition, the software is also capable of organizing multiple 3D parts so they nest, or perfectly fit, together on the print bed. This capability decreases the number of print jobs, which also lowers cost and increases speed.

“3D scanning and printing has revolutionised the speed and quality of parts we’re able to produce for clients.  Having the ability to create a bespoke devise that is lightweight, durable and accurate to 0.2mm has obvious benefits to the user. The business also benefits from the speed of 3D printing parts as well as cost savings of approximately 40% on each part by removing the need for multiple components in the supply chain and assembly,” said Mark Thaxter, Managing Director of Crispin Orthotics.

“Using 3D scanning and printing also provides greater freedom on the design of products particularly those with complex geometry.  Having the ability to vary the thickness of the device in certain parts also allows us to produce devices not possible with current methods of manufacturing.”

Crispin used its new HP MJF 3D printer, and its Siemens NX CAD, during a recent project. The combined technologies made it possible for the company to create a 3D printed arm orthotic with an integrated elbow joint and an attachment at the end, which makes it possible to pair up prosthetic devices with it. The device was 3D printed in a single part out of a durable but lightweight nylon material.

The sample parts that Crispin 3D printed on its new HP 4200 MJF system passed all of the necessary tests. But even more impressive is that the parts all had homogeneous strength in the three separate build axes, which just goes to show that build orientation does not have any negative impacts on the quality or strength of 3D printed parts.
