Engineers and product designers have more rapid prototyping choices than an aficionado at an art fair. Stereolithography (SLA), selective laser sintering (SLS), fused deposition modeling (FDM) and direct metal laser sintering (DMLS) are but some of the available additive manufacturing (AM) technologies, which cover a range of materials from nylon, polycarbonate, PEEK (polyether ether ketone) […]

Oxford Performance Materials (OPM), South Windsor, Conn., made medical history in February when they received the first Food and Drug Administration (FDA) 510(k) clearance for their polymer laser-sintered OsteoFab Patient-Specific Cranial Device (OPSCD). The customizable implant is designed to restore voids in the skull caused by trauma or disease. Manufactured in a matter of hours […]

Thread Whirling Boosts Productivity

Ever since British machine inventor Henry Maudslay introduced the first modern screw-cutting lathe towards the end of the 18th century, machinists have been cussing him. True, the world as we know it couldn’t exist without screw threads, but that doesn’t make cutting them any easier. Compared to other turning operations, single-point threading is slow, requiring […]

Down to the Wire – ‘Spiderman’ microwire used in medical devices

Posted Leave a commentPosted in Medical and Dental

Spiders have been doing it for millions of years: Spinning out material that’s stronger than steel, and—metaphorically at least—lighter than air. Luckily for the spider, she doesn’t have to cut tight-tolerance features on her delicate tapestry, or twist it up into precision coils and helix shapes to catch her meals. The microwire industry is spinning […]
