Whereas 3D printing typically tends to current itself on the big scale and in spectacular vogue, different occasions it capabilities to serve fairly peculiar wants. An ideal instance could be the fabrication of small however essential components like clamps. UK-headquartered Spanlite makes a speciality of custom-made LED lighting and just lately discovered itself in want of interlocking, two-part cable clamps. Earlier than fabrication of the practical half, the corporate turned to voxeljet UK to create a mannequin of the clamp for testing through high-speed sintering (HSS) with polyamide 12.
Hearkening again to probably the most unique intent of 3D printing a long time in the past, corporations like voxeljet UK are capable of make cheap and speedy prototypes. Not solely are such components extra reasonably priced, however in addition they supply the identical excessive efficiency as these made by conventional methods, like injection molding. HSS has been in use by voxeljet since 2017 for the manufacturing of practical prototypes and components. The method is most corresponding to HP’s Multi Jet Fusion and was truly developed first earlier than commercialization by inkjet printhead producer Xaar. HSS entails melting powder, irradiated into layers underneath infrared gentle till the half is completed.
For Spanlite, the purpose was to enhance the energy and longevity of lighting panels, powered by light-emitting diodes, which use exponentially much less vitality and last as long as 25 occasions longer than typical lighting. In ordering clamps, Spanlite was targeted on containing each edge-lit practical partitions and particular person lights for purchasers engaged within the hospitality discipline, business and high-end markets.
Having accomplished profitable prototyping, Spanlite will now require roughly eight,000 cable clamps—and that’s simply per yr. Usually, that sort of quantity would require extra typical manufacturing, however the VX200 HSS is able to printing 500 clamps in a single job field. There have been quite a few particulars to take into accounts although, starting with creating components with actual dimensions for correct clamping drive. The designers created a number of fashions till a “appropriate part geometry” was produced.
This was the Spanlite staff’s first main expertise with 3D printing—with probably the most basic advantages on show—from the flexibility to carry out speedy prototyping and testing to producing components shortly and affordably, custom-made to precisely the shopper’s specs.
“After a brief take a look at part to excellent kind and performance, we have been capable of shortly transfer on to full manufacturing and meeting. And we’re positive that the clamps have been just the start,” stated Adrian Bowker, Managing Director at Spanlite. “We’re already within the strategy of figuring out new elements for 3D printing. The know-how provides us varied benefits in each the design and the sequence manufacturing of the elements we’d like.”
The components needed to be measured appropriately for performance, however in addition they needed to meet in depth mechanical necessities. The order was accomplished on the voxeljet Friedberg service middle, a facility providing complete 3D printing with polymers, floor ending, and coloring.
“For us, the beauty of 3D printing from voxeljet was that it not solely met an preliminary want, the cable pressure reduction, however that we have been additionally capable of combine extra shapes and capabilities into the part with out incurring extra prices,” stated Bowker.
voxeljet continues to be a dynamic presence within the 3D printing business, from creating supplies and techniques to creating new additive manufacturing processes, and increasing their international presence in India just lately. We’re additionally now seeing HSS make its manner into the market and exhibit its potential for competing in opposition to Multi Jet Fusion to provide massive batches of components.
