西班牙3D打印机制造商BCN3D已经启动了其Epsilon W27和W50系统的升级版本。
Featuring an improved ventilation system, motor drivers, and mainboards, BCN3D’s new W27 and W50 machines are said to provide more engine torque and enable production with greater efficiency. Both units also ship with an internal web server that facilitates remote file sharing as well as print monitoring, which can now be enjoyed by previous-generation Epsilon users via an official firmware update.
BCN3D’s IDEX technology
尽管BCN3D推出了粘性光刻制造（VLM）是其第一个3D打印技术，去年，它是融合细丝制造（FFF）机器的制造商。2015年，该公司通过独立双重挤压（IDEX）技术（BCN3D Sigma）启动了第一台3D打印机，并在Sigma品牌下继续进行市场系统，直到今天Sigma D25.
Thanks to its IDEX configuration, the D25 is able to produce mirrored or duplicated parts, in a way that effectively doubles users’ throughputs. To make this as easy as possible to achieve (and ensure a perfect first layer each time), the machine also comes with an autocalibration functionality. This measures multiple points, before adjusting the print surface height and XY offset between both nozzles.
D25的继任者Sigmax发起后，BCN3D从CIM-UPC技术中心at which it was founded. Since then, the company has focused more on industrial-grade solutions, introducing theEpsilon W50和W27systems in 2020. While these still incorporate the firm’s signature IDEX setup, they also pack features such as larger build volumes and full enclosures, which make them better suited to heavy-duty end-use 3D printing applications.
Over the last two years, BCN3D has continued to support the machines with a range of accessories, including a dedicatedSmart Cabinet, which enables filament humidity control, and it has now unveiled hardware upgrades for both units.
升级W27和W50
Users of the original W27 and W50 will initially find the new versions to be very familiar. Both feature the same build volume and fully-enclosed passively heated chamber as before, the latter of which enables their beds to hit temperatures of up to 120ºC. This ensures the systems can be deployed alongside the same industrial-grade materials as their predecessors and boosts print predictability.
However, there have been noticeable changes in other areas. The machines’ distinctive black frames have been remodelled, so they now not only look sleeker, but they’re more robust and rigid in a way that ensures the correct parallelism of their axes. Under the hood, there has been an even bigger revamp, with the W27 and W50s’ Trinamic TMC2130 motors being replaced by quieter TMC2226s.
When it comes to ventilation, both have also received an upgrade. Whereas the machines’ previous system introduced cold air inside the fans with extraction towards another grid, the firm found that this caused turbulence in the interior. As a result, BCN3D has changed their designs, so that hot air flow is extracted from the interior, lowering internal pressure to let the interior absorb air from the outside.
最终，借助W27和W50的主板，该公司现在决定从商业上切换到定制组件。这些不是由在打印机的各个区域中实施的几块形成，而是集中在一个板上，据说使它们比以前更有效。
