Famous Czech manufacturer Josef Prusa, behind the\u00a0open-source 3D printers<\/a>\u00a0of the same name, recently unveiled a brand new SLA machine, the Prusa SL1.\u00a0In the continuity of its expansion – the company today employs 320 people, Prusa has decided to expand its range of 3D printers and turn to another technology,\u00a0stereolithography<\/a>.\u00a0His new SL1 machine is based on the MSLA process and would consist of a rigid frame. This improving its stability and thus the final impression.\u00a0It is already available for preorder from $1599 and should be delivered next December.<\/p>\n

Prusa is one of the most recognised manufacturers on the market, including its 3D kit printer, the\u00a0i3 MK3<\/a>\u00a0whose design has inspired more than one.\u00a0The Czech wanted to extend its expertise and embarks on another technology, stereolithography.\u00a0He joins the Polish manufacturer Zortrax who announced the release of its first\u00a0Inkspire<\/a>\u00a0resin machine\u00a0\u00a0a few days ago.\u00a0Will Prusa\u00a0manage\u00a0to compete with players already well established in this niche like\u00a0Formlabs with its Form 2<\/a>\u00a0or more recently the\u00a0Slash + from Uniz?<\/p>\n

The technical specifications of the Prusa SL1<\/h3>\n

According to the manufacturer, the 3D printer includes a 5.5 “high resolution LCD screen and has a print volume of 120 x 68 x 150 mm.\u00a0UV light cures an individual layer in 6 seconds before the tray rises to form another layer.\u00a0As for the structure of the printer itself, it is composed of a rigid frame. The frame offering more reliability and stability according to Prusa, but also a greatly simplified plateau calibration.\u00a0The SL1 would reach a layer height of 0.01 mm.<\/p>

But it is especially its resin tank that is one of the main characteristics of the Prusa SL1.\u00a0It has a transparent and flexible FEP film and can easily pull out.\u00a0Just below are the LCD screen and the heat source.\u00a0According to Prusa, this tank is equipped with a resin level sensor to prevent running out of material during printing.\u00a0As for the printing plate, it would include a motorised tilt function. This to avoid layer variations and mix the resin.\u00a0Josef Prusa explains: “This significantly improves the surface finish of the models and reduces the stress on the model that is less likely to come off the base<\/em>.”<\/p>\n

A post-processing machine is also offered with the 3D resin printer, which will facilitate the washing and cleaning process of the parts.\u00a0Regarding materials, Prusa claims that SL1 is compatible with most resins on the market.\u00a0Finally, the printer offers Wi-Fi connectivity and its touch screen will help all novices in the different stages of printing.\u00a0An ideal machine to make prototypes of jewels and pieces for the dental sector. But also for all artists, architects and designers.<\/p>\n

The manufacturer is quite confident about the features of its machine and its capabilities.\u00a0He says his users will be able to expect security mechanisms, detailed manuals and smart features. But also easy maintenance and accessible spare parts.\u00a0The Prusa SL1 3D Printer is available as a kit starting at $1299 and shipped in January 2019 while the assembled version costs $1599;\u00a0the first orders will be sent in December.\u00a0Czech is therefore positioning itself in a niche that is more affordable in terms of costs compared to other market players.<\/p>\n
