One of the key functionalities that distinguish amateur 3D printers from desktop-class devices is the open design, which significantly hinders (or in some cases even prevents) working with demanding engineering-class materials. Users of cheap, open 3D printers deal with this in various ways, building their own work chambers that maintain a relatively constant, elevated temperature. The most popular solution is the open-source design based on cheap Lack tables from IKEA, however, it requires some work and creativity, which means that few people in the end decide to build it. PRUSA Research is now introducing a ready-made solution, which, although more expensive than “cardboard” tables, looks much better and is incomparably easier to assemble.

Original Prusa Enclosure is adapted to the installation of 3D printers from the Original Prusa MK3S + series and one spool of filament. It is made of solid metal profiles and PETG side panels and does not require additional printing of additional components (not counting optional accessories such as carrying handles). The manufacturer declares that the housing reduces the odor generated by selected materials during 3D printing, as well as creates a stable working environment and maintains the elevated temperatures required for advanced materials susceptible to deformation (PC CF, Nylon, PP). It also significantly mutes the work of the 3D printer.

The design of the housing allows the installation of the LCD panel outside, which simplifies the control of the 3D printer and reduces its overheating. Built-in temperature sensor allows you to read the temperature inside the chamber. It is also adapted to further expansion – PRUSA assures that it will soon prepare and make available a list of additional accessories.

The chamber is not actively heated – the higher temperature inside it is caused by the heat given off by the 3D printer’s worktable. PRUSA is considering introducing an independent heater in the future, but it will be limited anyway – many components of the 3D printer are printed, so temperatures above 50 ° C could deform them (apart from the issue of overheating of the device itself).

The manufacturer declares that the following temperatures are achieved:

  • 33°C when printing PLA
  • 36°C when printing PETG
  • 38°C when printing ASA
  • 39°C when printing PC BLEND.

They are quite low by the standards of industrial 3D printing (in Stratasys machines, 3D printing from ABS takes place at a temperature of approx. 100°C), so you should not expect any dramatic improvement in the quality of work here. This type of chamber “helps” in working with engineering plastics, but by no means solves their typical problems with shrinkage.

The housing costs EUR 369. You can order it today – shipping starts in July 2022.
