Leveraging a recently purchased Stratasys J35 Pro system, the company says it has been able to improve both the design and delivery times of its new products. Specifically, Sepura is now able to create much more sophisticated prototypes, at lower cost, while reducing production lead times from two weeks to a single day.
“We are often asked to design custom solutions to meet specific user needs and develop in cooperation with customers,” said Robert Wright, Senior mechanical design engineer at Sepura. “We already knew the benefits of 3D printing for using the PolyJet technology Stratasys in the past.
The new approach to Sepura for rapid prototyping
Based in the city of Cambridge, Sepura specializes in the design and manufacture of mobile radio devices for applications such as public safety, as well as commercial businesses. The company’s own communications technology is the backbone of many rapid response organizations, including police forces, fire departments, ambulance services and public transport.
Due to the high-stakes nature of its customers’ work, Sepura’s product prototypes must be realistic. It is crucial for the company to be able to quickly and easily validate its prototypes for dimensional fit and reliability before deploying the designs in the field.
Since installing the J35 Pro, Sepura has used the system to rapidly prototype test models for its upcoming radios and functional test parts for battery development purposes. Additionally, the machine allowed for faster design iterations and shorter development cycles.
Wright adds: “The J35 Pro adds another important layer to our existing 3D printing capabilities – not only can we now create cost models true-to-life prototypes in-house, but we have also reduced our production times by 90%, which is more than we could have imagined.”
The Stratasys J35 Pro
The J35 Pro is known for being Stratasys’ first multi-material 3D printer designed for the desktop. Characterized by its distinctly compact frame, the system can combine up to three different polymer materials per construction, enabling everything from high-fidelity decorative pieces to functional engineering prototypes. The machine also lends itself to hands-free dissolvable media, streamlining the post-processing workflow.
Designed for use in the office, the J35 Pro is both silent and odorless. It also requires minimal maintenance due to its use of a rotating build plate, which means there aren’t many moving parts inside.
“The variety of materials available with the D35 Pro enables us to create accurate prototypes and means that our customers receive a detailed tangible model they can hold in their hands, move and try,” said Paul Tindall, responsible for R & D at Sepura. “We found that the Elastico ™ material was particularly beneficial. – we are able to produce sealing prototypes that simulate the look, feel and function of rubber and can withstand bending and repeated bending”
The applications of the Stratasys technology extend far. Earlier this year, the company made a new Discovery+ documentary, Radford Returns, when he designed and 3D printed over 500 parts for a revival of the classic Lotus Type 62-2 sports car. The team used the F900, F770, Fortus 450mc, F370, and J55 3D printers to produce different desired results for a variety of parts, including large composite firewall sandwich cores and smaller exterior elements like mirror housings. side.
Moreover, Stratasys recently associated with the digital services company United States to provide printed anatomical 3D modeling services at point of service to health facilities. As part of this partnership, Stratasys 3D printing technology will be integrated workflow Ricoh 3D for Healthcare Ricoh USA to increase access to medical printed 3D models for medical institutions and clinicians.
