The UltiMaker S3 3D printer takes many of the best features from the UltiMaker S5 and combines them into a smaller, more budget-friendly device. The UltiMaker S3 delivers the same high-quality, composite-ready dual extrusion, with the same market-leading reliability and ease of use – just with a smaller build volume (230 x 190 x 200 mm or 9.1 x 7.4 x 7.9 inches).
 
Key features include:
 
Network connectivity: Print via Wi-Fi, LAN, cloud, or with USB
Touch screen: Effortless operation via an award-winning user interface
Advanced active leveling: Reliable first-layer adhesion, enables unattended use
Front enclosure: Improved printing environment for better print results
Flow sensor: Stay informed when filament runs out to increase print success
Easy setup and monitoring: With NFC material recognition and internal camera
Composite materials compatible: Print parts with high strength and unique properties
 
From the ground up, the Ultimaker S3 has been meticulously crafted to live up to the renowned print quality associated with Ultimaker's S-line of 3D printers. Inside the Ultimaker S3, you'll discover a host of exceptional features:
 
Reinforced feeder wheels crafted from coated, hardened steel empower abrasion-resistant 3D printing, allowing you to create high-strength parts with glass or carbon fiber composites when paired with the Ultimaker print core CC Red.
Dual filament flow sensors enhance your print success rate by detecting filament depletion and immediately pause your print, notifying you to replace the spool, ensuring uninterrupted printing.
Advanced active leveling that ensures easy and reliable first-layer adhesion. The Ultimaker S3 employs precise build area probing and Z-height build plate compensation at the start of each print job, allowing you to initiate printing and focus on your tasks.
High-accuracy stepper drivers taken directly from the Ultimaker S5. These high-precision drivers are quieter than the Ultimaker 3 and run more reliably to consistently provide high-quality prints.
 
The Ultimaker S3 impressively crams an array of features into its compact form, offering a powerhouse of 3D printing capabilities in a remarkably small footprint:
 
Rigid printer frame reduces small vibrations (or ringing) while printing to improve overall print quality
Single glass door with a magnetic latch provides a more controlled build environment and reduces the risk of warping or delamination
Optimized internal design allowing both dual extrusion nozzles to reach the whole build area, and maintaining a high build-volume-to-size ratio
Internal power supply removes the need to make space for a power brick. It also makes the setup process easy across all S-line 3D printers
 
There's a wide range of Ultimaker-brand materials to choose from: 
 
Tough PLA, PLA, Nylon, ABS, CPE, CPE+, Polycarbonate, TPU 95A, Polypropylene, PVA, and Breakaway. Additionally, as with any Ultimaker 3D printer, you’re free to use any brand and type of material you wish. The Ultimaker S3 can handle any 2.85mm materials that extrude up to 280C.
