SnapMaker J1s Review: IDEX Fully Enclosed 3D Printer, Multiple-Color & Multiple-Filament 3D Printing

Overview

The Snapmaker J1 IDEX printer is a versatile machine boasting an independent dual extruder that enables simultaneous printing, which means it can handle two models at once or a single model with two different filaments. It is designed with a keen focus on multitasking and efficiency in 3D printing projects. The machine's construction includes a motion system with linear rails on the X and Y axes and linear rods on the Z axis, ensuring smooth and precise movements.

Features and Design

One of its standout features is the ability to easily switch between different types of extruders thanks to its modular design, which is a significant advantage for those requiring versatility in their printing materials and methods. The printer can reach a maximum nozzle temperature of 300°C and a heated bed temperature of up to 100°C, accommodating a wide range of filament types. The heated bed itself is a PCB type, equipped with calibration spots for bed leveling and setting Z offsets for both extruders.

Software and Usability

The Snapmaker J1 comes with proprietary, Marlin-based firmware, showcasing a departure from the commonality of Clipper firmware in the market. It supports Wi-Fi printing through its own Luban software, which complements other Snapmaker devices well, offering a unified ecosystem for those invested in Snapmaker’s line of products. This printer is also fully enclosed, featuring a 5-inch touchscreen, filament sensors, LED lights, and an easy calibration process guided by an on-screen wizard, which simplifies setup and ongoing use.

Performance

Performance-wise, its dual extruder system stands out by offering fast color switching with minimal filament waste, a significant efficiency boost over single extruder, multi-filament systems. The calibration for dual extrusion is smartly designed, utilizing a CNC probe method for X and Y offsets, ensuring accurate and hassle-free setup. Printing quality is commendable across a variety of materials and models, from simple PLA to more demanding polycarbonate and ABS, partly thanks to the enclosure maintaining a stable temperature environment.

Software and Filament

The Luban software, despite some minor limitations, provides functional slicing and local network print capabilities without security concerns associated with cloud-based operations. Additionally, the Snapmaker J1’s compatibility with a wide range of filaments, including PLA, PETG, TPU, and special support materials, underscores its versatility, especially when coupled with the possibility of printing parts that require different materials in a single job.

Pros and Cons

Pros include its high build quality, efficient dual extrusion, convenient calibration methods, and the ability to print a variety of materials, including complex support setups. However, it does have its drawbacks, such as reliance on manual calibration for advanced features like linear advance and input shaper, potential nozzle clogging when switching between significantly different materials, and the need to purchase additional hardened steel hot ends for abrasive materials. Despite these, it proves to be an adept machine for those requiring the flexibility of dual extrusion and the efficiency it brings to multifilament printing.

Conclusion

In sum, the Snapmaker J1 IDEX printer distinguishes itself as a powerful tool for enthusiasts and professionals alike seeking a reliable, versatile, and efficient 3D printing solution. Its ability to handle various materials, coupled with a robust build and thoughtful design, makes it a standout choice. While it may not be the fastest in purely PLA tasks compared to some Clipper-powered machines, its strengths in dual-material printing and enclosed environment capabilities make it a top contender for the title of the best performing IDEX printer in its class.
