LumiBee – A Mini Daylight Resin 3D Printer that You Can Create Yourself

Resin 3D Printer

LumiBee is a unique mini resin 3D printer that uses smartphone as a light source to polymerize the resin.

The LumiBee is a unique compact resin 3D printer that uses photosensitive liquid resin. It has been designed so that 95 proc. of its parts can be printed with a desktop LPD 3D printer. The project is free for everyone who wants to create their own device at home.

The LumiBee also stands out because it uses the screen of a mobile phone, inserted inside, to transform daylight liquid resin into a three-dimensional object. Daylight resin for 3D printing allows most smartphones to be used as a light source to solidify the resin. This allows us to give a second life to slightly outdated cell phones.

The LumiBee prototype was created on the Zortrax M200 3D printer – the predecessor of the Zortrax M200 Plus 3D printer.

Speaking about the resin 3D printer, Davide Marin CEO at Lumi Industries says, “I made LumiBee as a personal project. I developed mechanical design, PCB design, prototyping, firmware and App. I made first prototypes for the chassis using the FFF 3D printer we have in house, a Zortrax M200 and Z-ULTRAT filament. M200 provided us with everything we needed. The quality was good enough even to print threaded bars and nuts for LumiBee Z-axis.  An idea popped into my mind that LumiBee parts should be designed in a way that any user can 3D print them at home with a domestic FFF printer at a very low cost. I decided with my team to release LumiBee as free Open Source project by Lumi Industries, perfectly matching our mission to make 3D printing benefits available to a larger public”.

The LumiBee chassis design was split into “segments” with specific functions: holding the phone, housing the PCB board, etc., and they can be customized or replaced easily. In prototyping process each segment was printed in a different colour to highlight this feature. The name LumiBee is not an accident. At the prototyping stage, the studio had two filament colours available: black and yellow. The finished device resembled a bee, and this resemblance went way beyond appearance.        

Davide Marin adds, “In nature, this tiny animal has such an important role in our lives. It contributes to complex, interconnected ecosystems and we felt this reflected also the idea of the project itself involving different players like makers, 3D printing lovers and fans, as well as different companies to cooperate for the good and, if possible even improved, outcome of the project”.

Partners of the project are Photocentric providing suitable daylight resins, Zortrax – creator of the printer on which LumiBee was printed and 3D Filium, suggesting particular filaments, like their new coming non-flammable PlaQ FRVO, perfect for extra safety when embedding electronic components.

Speaking about the contribution, Rafał Tomasiak, CEO of Zortrax said, “We are glad that users of Zortrax printers use our equipment for creative projects and share their solutions with the tech enthusiasts’ community. The ability to create your own devices, modify and improve them is one of the most important things 3D printing brings to the table. We are excited to see how people will transform and modify LumiBee in the future”.

LumiBee open source project looks simple, but packs some smart solutions. For example, LumiBee communicates easily with any smartphone in the market. Every smartphone has a built-in flash for the rear camera, and accessing it is easy in Android studio. Communication protocol was reduced to the bare minimum, using a quick blink of the smartphone flash to say ‘go up 1 layer in the Z-axis’ to LumiBee and 2 quick blinks to communicate ‘print is finished, put the tray completely out of the resin’.

LumiBee was a finalist in 2019 edition of the Purmundus challenge at FormNext, Frankfurt. The M200 3D printer model used to create the LumiBee is the predecessor of the Zortrax product – the M200 Plus 3D printer.

Users can be a part of LumiBee project by downloading files from the official website and creating their own machine.
