In addition to production repeatability and high-performance material, Raise3D focuses the development of this 3D printer on high speed and large build volume.
3D printer manufacturer Raise3D has launched a new large format FFF printer for small-batch production in industrial applications. Named RMF500, the new printer is probably the first one in Raise3D’s portfolio to process carbon-fiber reinforced material with industrial-grade precision and repeatability.
With a build area of 500 x 500 x 500mm, the new machine can print speeds of up 300mm/s along with an acceleration of up to 2G and movement of up to 1000mm/s. The printer features an Independent Dual Extruder system (IDEX) which can enable 2 print jobs simultaneously, resulting this way in a faster and more productive process.
As far as production repeatability is concerned, the new member in the manufacturer’s portfolio can fabricate models with an accuracy of 0.001mm along the X and Y-axes. It is said to achieve precision of 0.0009765mm along the Z-axis. Its 1μm closed-loop synchronous control reduces speed variations with load changes of the motor, enhancing precision even further, a press release reports.
One of the challenges at the materials level, was to ensure that the machine processes materials that could enable the production of strong end-use parts without being interrupted. With carbon fiber, a reinforced filament with higher rigidity and lower shrinkage ratio, there is no need to a heated chamber – therefore no warping.
This leads to a far more efficient printer, that does not need to draw so much power, using 120W to power a single hotend. The resulting parts made from the carbon fiber reinforced filament are lightweight yet extremely strong, making them a potentially perfect alternative to metal parts, the company explains.
To ensure customers experience trouble-free, uninterrupted printing, the RMF500 is equipped with four 2.5kg super large cartridge (main and auxiliary, with sets each), where the 3D printer can switch automatically between main/auxiliary cartridges and reducing the need for constant intervention. Positive pressure humidity control keeps chamber humidity under 5% relative humidity.
Lastly, all load-bearing structural parts of the RMF500 are made of high-grade harden steel, with the maximum load the Z-axis can withstand being around 100kg. The linear motor driven system has low clearance and low maintenance requirements. The deflection error of Z axis with a high load in the entire moving range is estimated to be 50% lower than that of competitive products, the company concludes.
