Prusa Research launches an open-source resin 3D printer called. Let‘s review the specs of this highly interesting machine.
While you’re reading this, the race for affordable SLA printers is in full effect. With Joe Prusa pre-launching his resin-based 3D printer “Original Prusa SL1” plus an accompanying curing station, SLA printing is getting more interesting and professional in the low-cost segment. And yes, it is also open source.
Prusa Research has been known for its groundbreaking desktop FFF filament based printers. For the past ten years, Prusa has worked on non-resin 3D printing processes and grown his team to 320 people. Impressively, the company now produces around 6,000 3D printers per month.
His new project is the launch of a resin-based printer called Original Prusa SL1. To ensure that it could compete with others working in resin, Prusa explains that earlier this year he acquired Czech company Futur3D.
Futur3D specializes in resin printing, when they moved into the Prusa HQ they brought their expertise with them. Prusa explains that this is how he can ensure the Prusa SL1 is “really awesome right from the start.”
In a new blog post, Prusa adds that resin printing was previously only done by big corporations and at premium prices. He adds: “We may not wear suits, but we have an incredible amount of new ideas and we are willing to work our asses off, which is something corporations usually lack.”
Better yet, in true Prusa style, all resin-printers from the company, starting with the Prusa SL1, will be open-source.
The new Prusa SL1 will use MSLA printing approach (based on LCD curing) which Prusa adds is more accurate compared to the DLP process as it avoids the latter’s distortion problem.
Another interesting feature of the Prusa SL1 is that the resin tank is removable and has a flexible transparent FEP film on the bottom. It has a motorized tilt function. After a single layer has been cured, it is not lifted vertically from the bottom of the tank.
Rather, the tank tilts which Prusa explains improves the surface finish of models and reduces the stress of the model. This is thanks to the rigid build of the printer.
A few other notable features include:
Prusa explains: “Original Prusa i3 MK3 was a major step forward in terms of reliability and ease of use thanks to its many sensors and smart features. I actually said that MK3 is ‘bloody smart’. And SL1 will be no different. You can expect smart features, safety mechanisms, detailed manuals and handbooks, 24/7 live support, perfectly described functions, easy maintenance, and cheap spare parts… things that are usually not found in cheap Chinese 3D printers.”
The company also offers a dedicated curing and washing machine (see below).
This 2-in-1 machine is quite unusual, as is does curing and washing in one go. You insert a tank with isopropyl alcohol, put your 3D printed object inside and the magnet-driven propeller will stir the IPA and wash the printed object. It uses standard food preparation containers, so you can easily switch them out. Once you remove the tank and place only the printed object inside the machine, it will start curing it with UV light.
The yet-to-be-named machine is an optional accessory, but everyone who worked with resin knows this machine is not just a gimmick, but a huge improvement over handling isopropanol tanks with sticky fingers.
All3DP had a chance to take a look at the printed samples and was impressed with the details the printer seems to be able to deliver.
The Original Prusa SL1 is currently available for pre-order. Prusa is also offering special discounted prices for early adopters. The assembled Prusa SL1 3D printer costs $1,599. These first batch will start shipping in December 2018.
If you’d rather order a kit which requires assembly, the price is $1,299 and starts shipping in January 2019.
