3D打印系统制造商Onulishas launched an industry-first machine that’s capable of turning expired UV resin into a safely-disposable solid plastic.
Built around Onulis’ patented Waste Resin Axial Printing (WRAP) technology, theW7500allows adopters to recycle used or expired UV feedstock into materials that don’t require specialized end-of-life disposal. According to its creators, the fully-automatic machine’s ability to reuse resin allows it to “operate at virtually zero cost,” while yielding plastics with potential product prototyping applications.
解开“包装”技术
Founded with the stated aim of developing products that help resolve 3D printing’s biggest pain points, Onulis’ new launch targets one of resin printing’s most problematic issues: waste material disposal. At present, the firm says that disposing of used or expired UV resin requires manufacturers to either embrace “messy do-it-yourself methods” or costly services, who are forced to “simply bury sealed drums of hazardous material in landfills” to solve the problem.
If manufacturers do choose to go it alone, the time-consuming chore of resin disposal first involves manually exposing thin layers of used material to the sun, before stirring partially-cured polymers to continually reveal uncured underlayers. This painstaking process then needs to be repeated until the material is completely cured, in a workflow that can involve exposure to caustic materials.
What’s more, if a hazardous waste company is contracted, the manufacturer will first be forced to register with theEnvironmental Protection Agency作为这种浪费的发电机。在这种情况下，然后要求用户在现场存储大量的废物，直到收集足够数量的拾取数量为止。
W7500减轻了这些疼痛点，同时允许更快，更安全，更认真的回收利用，并且打印机生成的塑料实际上是零成本的库存，非常适合在CNC加工或产品设计中使用。
Onulis的W7500树脂回收室
Now being marketed to manufacturers, Onulis’ first WRAP technology-powered machine, the W7500, features a space-efficient formfactor, allowing it to be compact while retaining a 7.5 liter-capacity, and its broad compatibility means that it’s capable of processing waste and expired resins from SLA, DLP, PolyJet and MultiJet 3D printers as well.
由于其自动定时功能和轴向打印体系结构，W7500能够无人看管运行，并且还具有内置的碳过滤。结果，该系统致力于防止采用者在手动治愈紫外树脂时经常产生的有毒气体。该单元也包装出令人印象深刻的效率，使用户能够在短短六个小时内处理30天的垃圾树脂。
Industry-tested innovation
Initial adopters of the W7500 include users from multiple different industries, ranging from universities to medical device manufacturers and 3D printing service providers, with early customers keen to highlight its material efficiency benefits.
“我们的新W7500为我们提供了巨大的时间和成本节省，”加利福尼亚部分提供商和Onulis采用者的服务局经理Matthew DeGroat说。紫色豪猪。“我们很高兴惊讶的是，除了节省资金之外，我们还能够最大程度地减少团队与危险废物的接触，并重新将我们的劳动重新定位在高价值任务上。”
