The Prusa i3 MK3S+ has earned a reputation as one of the most reliable and feature-rich FDM 3D printers on the market. Building on the success of its predecessors, the MK3S+ continues to set the bar high for both hobbyists and professionals. After extensive testing, here’s an in-depth review that explores why this printer is often considered the gold standard in its category.
Design and Build Quality
The Prusa i3 MK3S+ showcases a thoughtfully engineered design, prioritizing both functionality and durability. Its frame is constructed from aluminum extrusions, ensuring stability and precision during printing. The orange and black color scheme is iconic and immediately recognizable, a testament to the brand’s identity. The printer comes either fully assembled or as a kit, allowing users to learn the intricacies of 3D printing if they opt to build it themselves.
The MK3S+ also features a magnetic, removable spring steel sheet with a PEI coating, making print removal effortless and reducing the risk of damaging prints or the build plate.
Print Quality
When it comes to print quality, the MK3S+ is in a league of its own. It delivers exceptional results with consistent layer lines, sharp details, and minimal artifacts. The printer’s precision is enhanced by its upgraded SuperPINDA probe for bed leveling, which ensures a perfect first layer every time. This is critical for achieving high-quality prints, especially for those working on intricate designs or complex mechanical parts.
Moreover, the MK3S+ excels with a variety of filament types, from standard PLA to more challenging materials like ABS, PETG, and flexible filaments. The extruder design, featuring a Bondtech drive gear system, provides reliable filament feeding and minimizes the risk of clogs or jams.
Performance and Features
One of the standout features of the Prusa i3 MK3S+ is its impressive array of smart sensors and fail-safes. The filament sensor, which detects if the filament runs out or becomes tangled, and the power loss recovery system, which allows prints to resume after a power outage, are invaluable for ensuring successful long prints. The printer’s quiet operation, thanks to the Trinamic stepper drivers, makes it a great choice for home or office use, where noise can be a concern.
The MK3S+ also supports advanced printing techniques like multi-material printing (with the optional Multi-Material Upgrade) and has a broad community of users who regularly share custom profiles and settings, making it easier to get the most out of this printer.
Ease of Use
The Prusa i3 MK3S+ is designed with user-friendliness in mind. The detailed assembly manual and robust online resources make it accessible even for beginners. Prusa’s custom version of Slic3r, known as PrusaSlicer, is intuitive and powerful, offering pre-configured profiles that are optimized for the printer. Additionally, the active Prusa community is a treasure trove of tips, troubleshooting advice, and modifications that can help users at all experience levels.
For those who opt for the kit version, assembling the MK3S+ is a rewarding experience that deepens your understanding of 3D printing technology. The assembly process is well-documented, with step-by-step instructions that leave little room for error.
