DPS Designs Ltd.
DPS Designs, a Gloucestershire-based supplier of moulds for the chocolate industry in the United Kingdom, had been reviewing its processes and looking towards moving to ‘digital engineering’ of its designs and the inspection of mould tools. At the time, a foam model would be manufactured from sketches and once approved by the customer, it would be drawn in 3D CAD to replicate the foam model. It was time consuming and difficult to make the CAD model exactly represent the foam model.
SOLUTION AND PRODUCT
Realising the benefits that 3D scanning could bring to this process, Leigh Down, DPS Design’s managing director, contacted Steinbichler UK, a distributor of optical measuring and testing technology from ZEISS Optotechnik. Following a demo together with testing and benchmarking, Down placed an order for a COMET LƎD system.
The 3D Scanning is used alongside Delcam’s Artcam software. The foam model is hand sculpted based on the customer sketches, photographs and technical requirements. Once the foam model is deemed to be as per ‘customer requirements’, the foam is 3D Scanned using the COMET LƎD system and the STL file sent electronically to the client for review. This process can be used as many times as required until the client approves the overall shape, proportions and posture of the model.
Upon customer approval, the STL file output from the COMET LƎD Scanner is imported into Artcam where the fine details are sculpted electronically with any draft angles for manufacture etc. added on in readiness for manufacture. Delcam PowerMill is then used to design the final tooling for manufacture.
RESULT / BENEFITS FOR THE CUSTOMER
“The acquisition of the COMET LƎD system has enabled us to speed up the development process significantly,” says Leigh Down. DPS Designs also uses the scanning to be able to provide 3D STL files to customers enabling them to review models electronically and efficiently. The LƎD system is key to the company’s future growth plans.
ADVANTAGES / STATEMENT
• Reduction of cycle times and significant speed-up of the development
• Easy and efficient handling of the CAD model
• Enabling customers to review models electronically and efficiently
• Increased quality
