Quick index print

Compared to a multi-material unit on a single extruder, IDEX bi-material printing requires less time in filament changes and creates less waste. Additionally, IDEX offers the cleanest dual-extruder solution that prevents cross-contamination.

Parallel printing

Halve waiting times, double productivity. IDEX is the only extrusion system with two separate extruders that move independently on the X-axis, allowing you to run two prints at the same time.

Copy mode : prints two identical objects at once. It is particularly suitable for batch printing, to empower studios and enthusiasts. If one of the prints encounters a problem, you can stop it without affecting the other. This mode is a real lifesaver for a promised delivery in a short time.

Mirror Mode : J1 directly mirrors your model and prints the original and mirrored one at once. For a symmetrical model, you can import half of it and print it in Mirror mode to reduce waiting times by 50%, perfect for quick sketches and concept models. As in Copy mode, you can interrupt one print without affecting the other.

Vibration compensation

The J1 offers a best-in-class print speed of 350mm/s while ensuring high print resolution. This is made possible by optimised vibration compensation technology. This technology reduces vibrations caused by high-speed movements, minimizing ringing to improve print quality. With the maximum acceleration of 10,000 mm/s², small, detailed models can be efficiently produced.

Seamless extruder switching and curvature optimization

During dual extrusion printing, the non-working extruder preheats while in standby and starts printing immediately after the working extruder exits, greatly reducing waiting time. By analyzing the extruder movement directions in advance, J1 can prevent problems such as corner bulging, providing better corner printing quality.

Speed ​​ensured by an elaborate hardware design

One-piece die casting: The body of J1 comprises a one-piece die-cast upper frame and base and four aluminum alloy bars. Building the body with a few highly integrated parts, an approach long adopted by the automotive industry, facilitates precision assembly. J1 is so rigid and reliable with minimal possible wobble and warping that you can print large projects one after another for a long time and get all the quality prints without compromise.

High precision linear guides : Industrial grade linear guides are made by CNC grinding at micron level, ensuring smooth and consistent movements. A significant increase in precision, rigidity and durability to let you enjoy a fast, accurate and consistent manufacturing experience.

Aluminum alloy frame : J1 inherits Snapmaker's iconic all-metal design that users highly appreciate for its rigidity and durability. It provides better heat dissipation with the main board and power supply distributed on the base and aluminum alloy as the main material. All the electronics well oiled, at your command.

Detachable and dissolvable supports

Building and removing support can sometimes seem like rocket science, but we've done the math for you: stable support, clean interface, effortless removal, and minimal post-processing needed to maintain high dimensional accuracy. Peelable filament offers the same support as regular materials but is much easier to remove without the need for additional post-processing. J1 supports PVA and other soluble materials. By immersing the print, the supports dissolve, resulting in a smooth surface and excellent dimensional accuracy. When you're looking for complex geometry, hollow structures and exquisite details, this is for you.

Bimaterial printing

In one print, you get the most out of two sets of properties. Combines the strength of nylon with the flexibility of TPU for functional parts. It also prints multi-part objects. Without assembly, the object achieves stronger interconnections, making it less susceptible to compromise.

Advanced extruder technology

300°C Hot Ends: The maximum nozzle temperature of 300°C is useful when printing with high-temperature filaments, such as nylon, reinforced nylon, and PC. With silicone hot end socks that prevent heat loss, the filaments melt and heat up much faster. Anti-clogging designs make the flow as smooth as possible.

Dual Direct Drive: excellent extrusion accuracy that helps in the extrusion of flexible filaments, together with the high responsiveness of the dual direct drives to make the deposition faster, more uniform and more precisely controlled. It is integrated with a filament sensor to inform you and pause the print job in case of filament running out, nozzle clogging and other abnormalities that fail to load filament.

Compact extrusion path: The uniquely designed compact extrusion path allows for hassle-free printing with TPU and many other flexible materials.

Closed space: provides stable environmental conditions to facilitate consistently reliable performance of high-temperature materials. For example, it prevents the deformation of ABS and many other materials.

Calibration done easily

We use electrical conduction to locate the two hot ends and the heated bed and measure the distances between the three entities, a creative solution to complex IDEX calibration. This time saving allows the calibration to be completed in 10 minutes in Assist mode. By removing the calibration card and judgment call, it reduces errors and achieves better accuracy.

Hands-free XY offset calibration: When the two hot ends touch the square opening on the heated bed, it sends electronic signals to suggest their exact positions and J1 calculates the offsets between them. J1 then automatically compensates for offsets during printing to ensure perfect XY alignment which avoids layer shifting and improves the success rate of dual-material prints. It takes away the long learning curve and saves you from poring over a lot of lines. Tap start and relax for high precision.

Tool-free bed leveling: A level print bed sets the stage for successful 3D prints, but leveling the bed on IDEX printers can be time-consuming. Using a high flatness PEI glass sheet, the J1 can reduce the size from a 3×3 (9-point) or 4×4 (16-point) leveling to a 3-point leveling without compromising flatness and reducing downtime by 70–80%. Turn the leveling wheel as directed on the touchscreen and the bed is leveled for first layer adhesion at the tip.

Easily manageable Z offset calibration: Using electrical conduction, J1 is able to calculate the distances between the hot ends and the heated bed. Therefore, we were able to reduce the back and forth movement of the calibration card when adjusting the Z offset. Simply turn the wheel as directed on the touchscreen and you are now the guru of Z offset calibration!

Custom PEI Glass Plate

The J1's build plate is made of glass with absolute flatness, making your first layer smooth and sticky. Polished glass on one side and PEI coating on the other, promoting the adhesion of various filaments. The plate can be easily removed so it is extremely useful for maintenance and removal of the print.

Easy to replace Hot Ends

Loosen the two screws on the hot end, fix or replace the hot end, and get right back to printing. For adventurers looking for more variations and advanced applications, we offer multi-diameter hot ends from 0.2mm for fine detail to 0.8mm for faster printing and hardened hot ends for technical materials.

Built-in nozzle cleaning

Scrape excess material from nozzles and stop extruder flow as soon as it activates to free multi-material prints from clumps and strings. The extruder can start its printing job inline without waiting for the newly active one to cool down. Switching between extruders takes much less time, again minimizing downtime.
