Original Prusa SL1 3D Printer Review

Original Prusa SL1 3D Printer Review

Last Updated on by Daniel Lawrence

3D printing innovation has made some amazing progress in a brief timeframe and keeping in mind that FFF (Fused Filament creation) is as yet the most famous organization, there are other technologies.  SLA or Stereolithography, for its complete name, is a type of 3D printing that utilizes a fluid sap instead of a strong fiber. A UV light from the print head is projected into the tar and fixes it layer-by-layer, when completed the abundance pitch is washed off and the print left to fix. As you can envision, there’s a lot of degree for the wreck, however, the subsequent prints are for the most part nothing not exactly incredible.  The SL1 is an MSLA 3D printer a variation of the SLA innovation.


Original Prusa SL1 3D Printer


The Original Prusa SL1 is one of those gadgets that has a moment attractive allure. When somebody strolls into the workshop, they’re looking at the thin dark and orange box. Esthetically it would appear that the business, huge straightforward orange door that flips open to uncover the forming plate and pitch tank. On the base is an enormous LCD contact screen that empowers you to explore settings rapidly. There’s nothing here that looks transparently Open-Source, this feels like a legitimate business product. That quality and accuracy summarize the plan and work of the SL1, it’s strong and should be to create SLA prints, as dissimilar to FFF printing there’s next to no edge for error. From the UV defensive orange way to the mechanical lead screw, strong metal tank, and fabricate plate, the SL1 in a flash feels one upon numerous different SLA printers that I’ve taken a look at.

Investigate, and you can see those little clues that this printer has its feet solidly situated in the realm of Open-Source. The fixing handle on the forming plate is 3D printed. There are a couple of other 3D-printed parts on the machine, for example, the cover check cover, blower fan pipe, and touchscreen outline, a little gesture to the Open-Source people group, and simply telling you could construct it on the off chance that you needed. Strangely the 3D printed part is printed with a FFF printer instead of SLA. The solitary explanation I can consider for this is that it’s less expensive to create and whenever printed by the SL1 you may not understand that the part was 3D printed. One part of the SL1 that immediately stands apart is size and weight. This is in no way, shape, or form a huge machine, and the little impression is ideal for an area in a workshop.

Although the printer is smaller, it has a decent weight to it, and a steady surface or table is the most ideal alternative. Albeit inactivity, the printer is calm and doesn’t vibrate or wobble similar to a FFF printer. In contrast to FFF printers, no material alternative empowers you to utilize this printer in a little kept space without the vapor getting to you. By the actual idea of SLA printing, it is more mechanical, and a respectable workshop is the most ideal choice or at any rate a very much vented room. Because of the channel get-together, you can join a hose and direct every one of the exhausts to space.

Availability can be a genuine 3D printing migraine, however here Prusa Research has selected each sort of association going, Wi-Fi, Network, and USB. Ease of utilization has been painstakingly thought of and opening the door; you can see that the forming plate is effectively removable once the print has finished. This element is fundamental because of the completing cycle that is needed with SLA prints.  Then there’s simply the bolt in a tank, the actual tank is strong and made to last, yet the transitory film base that will unavoidably debase after some time is replaceable. There’s a great deal to be said for the plan morals of Prusa Research ensuring that these parts are workable.


With regards to highlights, you can see the distinction between SLA and FFF 3D printers. SLA will definitely have a far more modest print stage and construct region than FFF, yet the print resolution will be far higher.

How about we investigate the primary highlights:

The openness strategy or MSLA framework utilizes an LCD screen to show a veil and a UV LED to fix the tar. The LCD is a 5.5-inch with a resolution of 2560x1440p, Quad HD or Wide QHD, and has a fixed XY resolution of 0.047mm (47um).

Each layer takes around 6 seconds to uncover whatever the size of the print, as it uncovered the whole layer in one go. The UV frequency is 405nm, and the light power is cca 990mW/m2.

The ball screw Z-hub, which looks unfathomably strong is controlled by the Trinamic stepper drivers empowering a base layer tallness of 0.01mm, the engines are additionally staggeringly calm. In spite of the fact that Prusa Research expresses the typical useful reach for a standard client is somewhere in the range of 0.025 and 0.1mm per layer.

The print space of an SLA printer is for the most part far more modest than that of a FFF printer, and here the SL1 has a space of 120x68x150mm. This probably won’t sound huge, yet in the SLA world, that is OK yet is as yet on the little side.

Sap can experience the ill effects of a wide range of issues; testing any SLA printer will feature nearly everybody in a brief timeframe. Prints adhering to the openness surface as opposed to the forming stage, relieved pieces of pitch skimming around thus the rundown goes on.

Different producers have thought of various arrangements, and here Prusa has gone for an extraordinary shifting tank.

It’s a nice methodology and keeps the gum traveling through the print cycle; it’s additionally far quicker than wiper arms and some different techniques utilized by different producers.

With regards to tar levels, you add tar by hand before the print, there are no lines or supplies to fill. The level of the gum is estimated by a sensor covered up away in the printing stage.

This action the volume of the pitch in the tank and guarantees that there’s sufficient sap to finish the work. Assuming the sap is beneath the necessary sum, an admonition will show up on the front LCD screen.

Another stand-apart element of the tank is the FEP straightforward film on the base. This can be supplanted when the film begins to stain or gets harmed.

To do this the bolts holding it set up can be eliminated and another FEP film can be put in. The interaction is simple and requires around 10 minutes to finish.

The SL1 is likewise not attached to restrictive gums and is viable with any UV-delicate fluid gum.

The forming stage, similarly as with a significant part of the development, is a strong metal and several highlights that guide with simple alignment and print expulsion.

A rotating appendage associates the principle arm to the forming stage, and this is delivered with the expectation of complimentary development during the bit by bit adjustment measure. There’s additionally a delivery handle on top that empowers the forming stage to be gotten out once a print is finished.

As far as I might be concerned, perhaps the main issue with SLA printing, besides managing the gum, is the smell. The whole cycle emits vapor, yet it is feasible to append a hose to the channel gathering and course that into an extractor.

Notwithstanding, there are a couple of plan components that assist with the smoke issue. A top covers the primary print region containing a portion of the exhaust and there’s a fan and channel at the rear of the machine. It would have been acceptable if the back extraction fan been able to interface into an extractor without any problem.

Sizewise the printer is entirely little and easily fits on most surfaces, even a rack, and measures in at 400x237x225mm.

A major piece of the Original PRUSA SL1 is the product. PrusaSlicer has developed constantly and is presently a considerable power.

The SL1 can speak with the product in a scope of ways, from direct association with Network, Wi-Fi, or USB.

On the facade of the machine is the control board, and of all 3D printers that I’ve seen, this is one of the clearest and simplest to utilize.

Introductory guidance for set-up then alignment are clear and brief, with pictures to help control you when required.

During printing, it shows you the advancement and empowers you to check settings and make acclimations to alternatives, for example, openness without any problem. The plan of the printer and programming is all extremely shrewd and smooth.

The Original Prusa SL1, a sap-based 3D printer, has a smart, strong plan and can convey excellent yield when the stars adjust. However, we invested an excess of energy investigating it or attempting to keep its sap tank clean.
