FFF vs SLA Basic Comparison

Original Prusa i3 MK3S+ (FFF printer)

Prints 3D objects by extruding melted plastic, compatible with materials such as PLA, PETG, ABS, flexible filaments and many more

Layer height 0.05 mm - 0.15 mm

Maximum print area size 25 x 21 x 21 cm (9.84 x 8.3 x 8.3 in)

Great for: prototyping, printing toys, RC models or mechanical parts

Post-processing: possible, depends on the type of used materials. Possible sanding, gluing, painting

Original Prusa SL1S (SLA printer)

Uses UV light pattern to cure layers of resin. Photo polymers are cured layer by layer to create the final object

Min layer height: 0.01 mm, recommended layer height: 0.025 - 0.1 mm

Maximum print area size: 127 × 80 × 150 mm (5 × 3.14 × 5.9 in)

Great for: prototyping, jewelry, art models, medical use (e.g. dental molds for casting)

Post-processing: easy, models can be glued, sanded and painted

Main Features

Great Print Quality

The SL1S features a new 5.96'' monochrome LCD with a physical resolution of 2560×1620p. Taking advantage of the completely reworked optics and the new monochrome display technology, the SL1S offers a vastly improved print quality compared to its predecessor.

Our Fastest Printer Ever

Configure your 3D printer with ease and see previews of sliced models before you start printing! Thanks to the 2.8’’, 240×320 LCD screen with 65.000 colors, every option is just a few clicks away.

Touch Controls and Network Features

Upload your print files over network and perform over-the-air firmware updates. The SL1S comes packed with modern technologies that make 3D printing easier, safer and more convenient than ever before. On-screen wizard will guide you through the whole setup process. You will be ready to print in no time!

25% Bigger Print Area

The SL1S features a 25% bigger print area compared to the SL1. The largest object that fits in the 127×80×150mm print area can finish under 4 hours (0.05mm layer height) or in 2 hours with 0.1mm layer height. This is also possible thanks to the nearly three times faster tilt compared to the SL1.

For Newcomers and Professionals

The SL1S is more than just a machine for producing figures and statues. With professional-level print quality, extensive documentation, low running costs and 24/7 tech support, the SL1S is perfect for newcomers and professionals alike. Its predecessor, the SL1, already found its way to hospitals and industrial companies.

High-Quality Materials and Rigid Body

We have built the Original Prusa SL1S 3D printer around a rigid, heavy aluminum body, which minimizes vibrations and ensures the best possible printing performance even when printing thin and highly detailed geometry. The SL1S features a quick-release mechanism, which maintains the Z-axis calibration.

Smart Resin Tank

The new tank from high-quality graphite-reinforced PA6 composite comes with a practical opaque lid that protects the resin from being cured by daylight. Automatic Resin Sensor prevents resin from overflowing or running out mid-print.

Slice with PrusaSlicer

The SL1S is fully supported in the latest releases of PrusaSlicer, our internally developed and regularly updated slicing software. Take advantage of hollowing, automatic support generation, easy object manipulation and many other tools. PrusaSlicer also contains factory-tested profiles for dozens of resins.

Original Prusa Curing and Washing Machine CW1S

CW1S is a post-processing device for resin-based 3D prints. The CW1S is a 4-in-1 device, which makes the otherwise long and messy process a breeze. What it can do?


The finished print has to be washed to remove the uncured resin from its surface. CW1S uses a stainless steel tank for isopropyl alcohol and a magnetic propeller. This method is less aggressive compared to ultrasonic cleaning and works very well even with very small objects.


Drying a washed model is yet another feature of the multipurpose CW1S. Before the washed model is cured with UV-light, it has to be dried in order to avoid resin residue stains.


Curing the model with UV-light is an essential part of the resin printing process. Printed objects are usually soft, so treating them with UV light gives them optimal surface properties.

Resin Pre-heat

CW1S can preheat the resin before printing it, thus getting it to the ideal printing temperature and state for the best performance of the SL1S and the resin itself.

Case Studies

Medicine (Surgery)

Neu3D Laboratories, based in Lefkosa, TRNC, operates under the Experimental Medical Research Centre of Near East University. The institute uses 3D printing to advance surgery methods. The SL1 is used to print test models for flexible bronchoscopy simulation.

Medicine (Dental)

Asana Dental uses a special suction system designed by Dr. Vit Payma and Lukas Pekarek. The system is printed on the SL1 and helps dentists to reduce risks during the Covid-19 pandemic by eliminating potentially hazardous aerosol.

Professional Models

Professional-grade miniatures by David Damek are wonderful recreations of their real-life counterparts. Intricate details and high print quality are an absolute must. "Printing with the SL1 made my work much easier and opened doors to unlimited creativity," Damek says.


SLA printers are precise enough to print even the smallest details. This makes them useful for the process of designing and manufacturing casting jewelry models. SL1S is a perfect match for jewelry professionals all around the world.
