關於 The New LumiFold TB 便攜式樹脂3D打印機

New Lumifold是一種旨在使3D打印機小於其打印體積的系統。它佔用的空間很小，可以放在手提箱中，也可以在需要的地方使用。這打開了新的場景：發展中國家或緊急地區的醫生可以在需要他/她工作的地方進行3D打印旅行，老師可以在上課時建立3D文件，設計師可以為客戶和與客戶一起創建原型。現場演講。 TB是基於光固化樹脂的版本，它使用日光3D樹脂和簡單平板電腦的屏幕作為3D打印的主角。

新聞資料包

由設計師提供嘅製作人員名單、團隊成員同技術詳情。

獨特屬性: The New Lumifold TB is an innovative 3D printer designed to be compact and transportable. Using an iPad Tablet as light source, the New LumiFold has a resolution on xy axis of 78 microns. The tablet is inserted under the resin vat, under a Fep film. An App processes the 3D file. Once it is ready, you just click start: the 3D printer, connected via Bluetooth to the iPad, will move up each time that a layer has been cured thanks to the light emitted by the screen.
尺寸同包裝: The New LumiFold TB size is 180 x 280 x 80 mm when it's closed. When fully open the height is 180 mm. The 3d printing volume is approx. 100 x 100 x 100 mm.
標籤: 3d printer, DIY, 3d printable, 3d printing
生產技術: Most of the parts of the New LumiFold TB are made by CNC machined aluminum on 5axis mills. The top part is a block of acrylic that has been milled, polished, and dyed with a UV-blocking pigment.
設計挑戰: Its most interesting feature is that the total height of the 3D printer, when closed, is smaller than the maximum height of the 3D printed part, as it expands while 3d printing. In the last years we have seen many innovations in the way the resin is cured, but the mechanical lifting system is mostly unchanged; we spent more than 2 years to develop and refine a scissor-like mechanical system, and went to more than 6 iterations.
研究: My main focus was to find the correct engineering solution to obtain a precise mechanical scissor system, using small components not to alter the ultra-compact design I conceived. I did several interactions changing motor types and threaded bars, introducing distance sensors to get an accurate movement which can allow to 3D print up to 25 micron on Z axis. Second focus was on the structure material for it to be light to carry but stable enough to provide detailed 3D prints. The result is a mix of aluminium and acrylic parts providing a fine and clean design.
靈感: A compact, even portable, 3D printer has several advantages. New LumiFold TB name originates from "Lumi", since 3D printing technology implemented in it uses 3D resins cured by light. In this case, by a tablet screen light, therefore the final "TB". "Fold", because the 3D printer really folds on itself to become extra compact. "New", because it is the evolution of a previous project. Presented in 2013, Lumifold was a foldable 3D printer body using an external DLP beamer for 3D printing light curing resins. It introduced the idea of portability in stereolithography Additive Manufacturing.
項目時長: The first idea of a mechanical system allowing an additive manufacturing device to be ultra-compact started back in 2014 when I incorporated Lumi Industries startup, inside H-Farm incubator in Roncade (TV). I did first feasibility tests and a first proof of concept to answer needs of an early business partner. In late 2015 I filled a patent request which was granted in 2018. The development went on slowly through as many as 6 iterations. In 2018 I created a first version of New Lumifold stereolithography 3D printer using Daylight resin and a tablet as light source to take compactness to the extreme.
操作流程: The user opens a 3D file on the Tablet using our App. It slices and processes the 3D file. When it is ready, the screen switches to black; at this point, the tablet is inserted under the resin vat, into the machine. Now the user just presses start button: the 3D printer, connected via Bluetooth to the iPad, will move up each time that a layer has been cured thanks to the light emitted by the screen itself. After 3d printing is finished, the user removes the part, cleans it with detergent, and post-processes it with sunlight / external UV lamp.
