Spanish 3D printer manufacturerBCN3Dhas launched upgraded versions of its Epsilon W27 and W50 systems.
BCN3D的新W27和W50机器具有改进的通风系统，电动机驱动器和主板，据说可以提供更多的发动机扭矩，并以更高的效率使生产。这两个单元还使用内部Web服务器运送，该服务器促进远程文件共享以及打印监视，现在，前一代Epsilon用户可以通过官方固件更新来享受。
BCN3D’s IDEX technology
Though BCN3D launchedViscous Lithography Manufacturing(VLM)去年首次3 d打印技术,, it’s better known as a manufacturer of Fused Filament Fabrication (FFF) machines. In 2015, the firm launched its first 3D printer with Independent Dual Extrusion (IDEX) technology, the BCN3D Sigma, and it continues market systems under the Sigma brand to this day, with theSigma D25。
由于其IDEX配置，D25能够以有效的方式使用户的吞吐量翻倍，从而产生镜像或重复的零件。为了使其尽可能容易地实现（并确保每次完美的第一层），机器还具有自动校准功能。在调整两个喷嘴之间的打印表面高度和XY偏移之前，这将测量多个点。
Following the launch of the D25’s successor, the Sigmax, BCN3D was spun off from theCIM-UPC technology centerat which it was founded. Since then, the company has focused more on industrial-grade solutions, introducing theEpsilon W50 and 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.
在过去的两年中，BCN3D继续为机器提供一系列配件，包括专用的配件Smart Cabinet, which enables filament humidity control, and it has now unveiled hardware upgrades for both units.
Upgrading the W27 and W50
原始W27和W50的用户最初将发现新版本非常熟悉。两者都具有相同的构建体积和完全封闭的被动加热室，后者的床可以达到高达120ºC的温度。这样可以确保系统可以与其前身相同的工业级材料一起部署，并提高打印可预测性。
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.
在通风方面，两者也都进行了升级。尽管机器以前的系统以朝着另一个网格的方式提取了风扇内部的冷空气，但该公司发现这会导致内部湍流。结果，BCN3D改变了其设计，从而从内部提取热气流，从而降低了内部压力以使内部从外部吸收空气。
Finally, with the W27 and W50’s mainboards, the company has now decided to switch from commercial to custom-made components. Rather than being formed from several pieces implemented in various areas of the printer, these have been concentrated into a single board, in a way that’s said to make them far more efficient than before.
