AB-3D, a younger 3D printer producer based mostly in Prosselsheim, Germany, has showcased its D-PATCH 3D printer for the primary time at Formnext 2021.
The corporate’s debut prototype is a delta extrusion-based 3D printer working on AB-3D’s Fused Layer Modeling (FLM) course of. Curiously, the D-PATCH is supplied with an automated device changer system that allows the machine to 3D print with as much as 5 totally different supplies in a single print job.
Geared extra in direction of increased efficiency functions, the D-PATCH is able to processing filaments corresponding to PETG, TPU, PA, PC, and even ceramic- and metal-infused composites. As such, the 3D printer goes past simply multi-color prints and into the realm of multi-functional components, with use instances in each useful prototyping and end-use manufacturing.
Multi-material delta 3D printing with AB-3D
The mix of toolchanging and delta FDM isn’t one we frequently see within the 3D printing business. Delta coordinate techniques differ from the frequent cartesian setup because the printhead strikes in all three axes (XYZ) whereas the print mattress stays fully stationary. Past simply the aesthetics, delta printers are literally identified for his or her sooner journey and print speeds, because the weight of the one printhead is split between the three motors.
Regardless of the corporate’s infancy, AB-3D’s FLM expertise has already confirmed itself within the tutorial sphere, having been utilized by the Coburg College of Utilized Sciences for analysis tasks.
The D-PATCH additionally reached the semi-finals of an area German 3D printing competitors with the additive manufacturing of a multi-material industrial half.
The D-PATCH 3D printer
So far as preliminary prototypes go, the D-PATCH truly seems to be like a reasonably competent piece of equipment. The delta machine includes a cylindrical construct quantity of Ø300 x 400 mm, with a heated construct plate and an enclosed chamber able to sustaining temperatures of 60°C. Customers will be capable to select from a number of print floor choices, together with PEI coated spring metal, glass, BuildTak, and FR4/G10 glass fiber epoxy.
Though the machine solely has one printhead, the built-in device changer works to change between 5 totally different filaments on the fly, permitting for the manufacturing of multi-material, multi-functional builds.
To allow printing with these higher-performance filaments, the D-PATCH additionally gives a excessive nozzle temperature of 450°C. Customers will even be capable to substitute out the default nozzle for one more one higher suited to their wants – the listing of choices contains brass, chrome steel, nickel-plated copper, and extra.
Further options embrace Wi-Fi connectivity, automated mattress leveling, a filament runout sensor, energy loss restoration, and even a particle filtration system for secure and comfy indoor use.
