SainSmart INFI-20 Review: A Solid Choice for Intermediate 3D Printing Enthusiasts

The SainSmart INFI-20 stands out in the realm of consumer and educational 3D printers due to its specialization as an FDM/FFF printer designed to cater to intermediate and advanced users. Released in 2021, it primarily targets those keen on prototyping and engineering projects, giving makers an opportunity to dive into complex prints with a reliable platform. On paper, the INFI-20 combines a unique blend of accessible assembly and upgradeability with a build volume that encourages larger prints without sacrificing quality. This makes it an appealing contender for anyone looking to step beyond entry-level printing without breaking the bank.

Detailed Specs & Features

Breaking down the specifications further reveals why the INFI-20 garners interest. Its FDM/FFF printing technology remains a standard for accessible, material-efficient prototyping. The printer uses an internal power supply with a versatile voltage range of 100-120 V and 200-240 V, making it suitable for use in different regions. Its physical dimensions, approximately 21 by 26 by 14 inches, and a weight of around 41 pounds, make it relatively compact for a machine with its capabilities.

Most notably, the maximum build width of 7.87 inches combined with a build depth of 6.69 inches and an effectively unlimited build height (noted as 999.99 but realistically implying tall prints) speaks to its capacity for larger or taller prototypes. This expansive work area facilitates functional projects without frequent layer stacking constraints. When looking at print quality, the INFI-20 features a minimum layer resolution of 100 microns and can stretch to 400 microns for faster, rougher drafts. This flexibility aligns with its targeted audience, allowing precision work or rapid prototyping as needed.

The printer uses a standard 0.4mm nozzle with optional sizes available (0.4 mm, 0.6 mm, and 0.8 mm), which enables users to tune speed and detail according to their project demands. Another technical highlight includes having a Bowden extruder drive, which often contributes to reduced moving mass and improved print speed. Additionally, with a maximum extruder temperature of 452°F and a heated bed reaching 212°F, the printer supports a wide range of filaments from PLA and PETG to more flexible options like TPU and even wood-infused materials.

User Experience & Performance (Based on Specs)

Design & Build

The CoreXY frame design is notable for promoting speed and precision due to its efficient belt system that stabilizes motion in the XY plane. The open enclosure design, however, might not provide optimal temperature stability for certain advanced filaments, but it makes the printer easier to access and monitor. A modest 3.5-inch screen with a resolution of 128x64p gives the user a clear interface to control print jobs; still, it lacks the sophistication of touchscreens, which some competitors offer. Users need to manually calibrate the bed since the model does not support auto leveling, which might challenge beginners but benefits those who prefer manual fine-tuning. The sturdy build at roughly 41 pounds also adds to the overall stability during printing.

Performance

With an official maximum print speed of 100 mm/s, backed by a measured effective print speed of about 50 mm/s, this printer balances speed and print quality effectively. Operating noise rests at 50 dB, which is comparable to standard office conversation levels and acceptable for home workshops or classrooms. The ability to recover from power loss and a filament runout sensor adds practical, fail-safe elements rarely found at this price point. These ensure continuity and reduce waste, reinforcing the value proposition for moderately experienced users. Furthermore, the print quality rating of 4.0 out of 5 reflects a generally reliable output with room for optimization based on filament choice and print settings.

Camera / Display / Audio Quality

The lack of a built-in camera and the absence of remote monitoring or mobile app support could be seen as limiting for users who seek advanced workflow integration and real-time observation. The user interface is basic but functional, and the audible noise profile remains moderate due to the inclusion of efficient cooling fans.

Extra Features

The INFI-20 includes some thoughtful extras, such as a filament runout sensor and a power loss recovery feature, which help avoid failed prints. Safety-wise, this model holds important certifications, including CE, FCC, and RoHS, vital for peace of mind during prolonged use. It also features overheat protection and auto shutdown on error, adding layers of operational security.

Pros & Cons

Pros

• Robust CoreXY frame promoting speed and precision
• Wide filament compatibility, including flexible and wood-infused materials
• Useful features like the filament runout sensor and power loss recovery
• Safety certifications and protective features enhance user confidence

Cons

• No auto bed leveling - manual calibration required
• Lacks advanced connectivity options like remote monitoring or a mobile app
• Open frame design limits the use of certain temperature-sensitive filaments

Price & Value For Money

Priced at $424 at SainSmart.com, the INFI-20 offers a compelling package for users willing to invest in a capable kit. Given its 1-year warranty, various upgrade pathways, and a robust maximum extruder temperature of 452°F, the pricing feels justified for hobbyists and education environments alike. The manual assembly requirement and lack of some automation features indicate it's better suited for users comfortable with tinkering and calibration. Those seeking turnkey or plug-and-play printers might find better options elsewhere, but for the price, the INFI-20 provides a strong return in quality-to-cost ratio.

Quick Take

In short, the SainSmart INFI-20 blends a solid CoreXY mechanical design with versatile filament compatibility and thoughtful fail-safe features, all wrapped in an accessible package. If we look at the numbers alone, it balances affordability with performance well, particularly for intermediate makers. While it may not cater to beginners who prefer hands-off printing, it helps users achieve reliable, larger-scale prints with room for upgrade.

Closing Recommendation

The SainSmart INFI-20 may be ideal for users who have some 3D printing experience and want a larger print area without sacrificing customizability. Its strong safety certifications and practical features provide a trustworthy platform for educational settings or home prototyping. However, beginners or those requiring advanced connectivity and convenience might want to consider other models with auto-leveling or remote control options. Overall, this printer helps users achieve quality production with a flexible and future-proof approach.

Verdict

Rating: Based on the specifications and overall feature set, we believe SainSmart INFI-20 deserves 4.3 out of 5.

• Winner Feature => Robust CoreXY frame and flexible filament support make it versatile and precise.
• Needs Improvement => Manual calibration and limited connectivity hold back ease of use and advanced workflow integration.
