![]() Once a layer is done, the machine will vibrate slightly moving the next layer of metal powder onto the build platform, the arm will lift, and the process repeats. Working from the center out, an entire layer can be welded in a matter of seconds. At this point the arm is in contact with the metal powder, and an electrical current is sent to the arm. An arm will come down on top of the metal powder on the build platform. The Arc printer would work by using a thin layer of metal powder, which is printed layer by layer. The printer could easily be scaled up by simply adding additional wire arrays. The arrays would be individual modules which correlate to the X and Y coordinates fed to the printer via a slicing software. The head of the printer would be at the bottom of the print platform, which consists of many small wires placed in a 256 x 256 array. Sort of like many SLA printers which use UV light to cure a resin, this machine also works from the bottom up. The electric arc is able to produce intense heat of close to 6,500 degrees F, instantly melting and fusing the electrode and base metals. It is based on the same process used in the arc welding field, and according to the project’s designer, “the Arc printer is a rapid printing 3D printer with minimal moving parts designed to print objects in minutes not hours.”įor those of you unfamiliar with how arc welding works, it is a fusion welding process which uses a welding power supply to create an electric arc between an electrode and a base material which is fuses the metals together. The method described by ‘0n37w0’ is called arc printing. The self-proclaimed ‘Fixer of Things’ has posted a project on the site, which is dedicated to serving up fresh ‘hacks’ every day from around the internet.Īlthough the Hackaday user is limited on funding and time, he is slowly working on this idea, which he has posted in full at Hackaday.io. Cockroach has updated the log for 74181 4-bit ALU without transistors.One member of Hackaday.io, who goes by the handle of ‘on37w0’ (and introduces himself as George in his project’s video), thinks he may have discovered a new technique to 3D print metal objects at speeds which currently seem like a pipe dream. anudeep liked Analogue/discrete UART reciever.Sl_Postmann has updated the project titled Tablet Synth.胡凡 liked Homemade pocket thermal imager.FulanoDetail has updated the log for DIY Human-sized Mech. ![]() ![]() Alessandro Alfonzetti has added a new log for ESP-360-REMOTE.ziggurat29 has added a new log for ROM Disassembly - AlphaSmart Pro.Jhonatan Brandel liked Long Range Wireless Internet over 433Mhz.Joshua on Sailing On A Sea Of Seven-Segment Displays.Mandi on The USAF (Almost) Declares War On Illinois Radio Amateurs.TG on German Air Force Surplus Teardown.sjm4306 on Sailing On A Sea Of Seven-Segment Displays.BrightBlueJim on Answering Some Pico Balloon Questions.Twisty Plastic on Answering Some Pico Balloon Questions.Erixon on NASA Help Wanted: Ham Radio Operators Please Apply SUPERCON 2022: Kuba Tyszko Cracks Encrypted Software 5 Comments Posted in 3d Printer hacks Tagged 3d printing, arc printer To find out more, check out the Hackaday.io project page. A lifting mechanism is then lowered within electrical contact and the printing begins. The supply bin feeds granulated metal, possibly by vibration, onto the print bed. The printer is comprised of four main components (the print bed, the lifting device, the control box, and the granulated metal supply bin). We are still trying to wrap our heads around how this will work, but from the looks of it, arc printing “ is done by completing an electrical current on an area of granulated metal thus heating the metal enough to form a bond to the structure being printed.” is hoping solve this problem by working on a way to ‘print’ 3D objects using arcs of electricity. Sometimes you just need it done now,…not a few hours from now. It takes way too long, and occasionally, time is of the essence when prototyping products for a client. However, waiting for a 3D printer to complete its cycle is still a lot like watching paint dry. Items are now being created in hours, not days, which is an extraordinary leap in technology. Additive manufacturing, aka 3D printing, is able to produce wonderful and amazing objects in relatively short periods of time.
