Awards & Reviews
“The Snapmaker J1 is fast and attractive -- it's a printer you would actually want to put on your desk -- but it also uses a few different tricks to maximize output. IDEX printers have been around for a while, but they're often difficult to set up and hard to maintain. The J1 has made the setup a breeze.”
“The J1 is a workshop tool; there's no tinkering needed, nothing to add. It's a proficient 3D printer that does exactly what it's supposed to do. However, what makes it stand out is the pure reliability of the machine, and the way through the Luban software, you can very easily adjust the settings to match your exact needs.”
What is IDEX?
IDEX (Independent Dual Extrusion) is the only extrusion system with two separate extruders moving independently on the X-axis, enabling you to run two prints simultaneously. Plus, IDEX offers the cleanest two-extruder solution that prevents cross-contamination. It creates a clean interface between two materials, embracing hassle-free removal and avoiding stains and weird blending along the seam.
Print in parallel.
Halve your wait time, double your productivity.
Copy Mode
Print two identical objects in one go. It is especially suitable for batch printing, empowering small business and studios. If one of the prints runs into an issue, you can stop that print without affecting the other. This mode is a lifesaver for a promised delivery on a tight schedule.
Mirror Mode
J1s directly mirrors your model and prints the original and the mirrored one in one go. For a symmetrical model, you can import half of it and print it in Mirror Mode to cut your wait time by 50%, perfect for quick drafts and concept models. Like in the Copy Mode, you can stop one print without affecting the other.
Backup Mode
Under Backup Mode, you print with one extruder while the other stands by. If the working extruder bumps into a hiccup, the stand-by one would take over the job seamlessly and still deliver a fabulous print to you.

Dual-material printing
In one print, you make the most of two sets of properties. Combine the strength of nylon with the flexibility of TPU for functional parts that can stand daily wear and tear impressively.
Dual-color printing
Add a splash of personality to your concept models, miniatures, party essentials, gift items, and home decor.
Different materials on the walls and the infill
By printing infill with economical materials plus a large-diameter nozzle, you can now spend most of your time and money budget on working the exterior to perfection.

Support your creation.
Dissolvable support printing
J1s supports PVA and other dissolvable materials. Soak the print, and the supports dissolve, leading to a smooth surface and excellent dimensional accuracy. When you are looking for complex geometry, hollow structures, and exquisite details, this is for you.
Breakaway support printing
Breakaway filament offers the same support as normal materials but is much easier to remove without the need for further post-processing.
Less waste & faster filament changing.
Compared with a multi-material unit, IDEX dual-material printing requires less time in filament changing and creates less waste.

Vibration compensation.
J1s brings you a top-of-class printing speed of 350 mm/s while ensuring a high resolution of prints. It is made possible by the optimization of the vibration compensation technology. This technology reduces the vibrations caused by high-speed movements, minimizing ringing to enhance print quality. With the maximum acceleration of 10,000 mm/s², you can realize small models packed with details with efficiency.
Seamless extruders switching.
The non-working extruder preheats while on standby, and starts printing right after the working extruder leaves, significantly reducing your waiting time.

Strong print cooling system.
J1s has a strong print cooling system, comprising print cooling fans not only under the nozzles but also at the back panel. With a narrow fan duct blasting a wide area with air, the print cooling fan at the back can further cool your prints during high speed printing and lower the ambient temperature when printing materials like PLA.
Innovative IDEX calibration.
We utilize 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 saver enables you to complete the calibration in 10 minutes under the Assist Mode.Taking away the calibration card and the judgement call, it reduces errors and arrives at better accuracy.
Innovative IDEX calibration.
Hands-free XY offset calibration.
When the two hot ends touch the square opening on the heated bed, it sends out electronic signals to suggest their exact locations, and J1s calculates the offsets between them. J1s then auto-compensates the offsets during printing to ensure perfect XY alignment that avoids layer shifting and improves the success rate of dual-material prints. It takes away the long learning curve and saves you from scrutinizing through an awful lot of lines.
Tool-free bed leveling.
A level print bed lays the foundation for successful 3D prints, but the bed leveling of IDEX printers can be very time-consuming.

Using a PEI glass plate of high flatness, J1 can downsize from a 3 × 3 (9 points) or 4 × 4 (16 points) leveling to a 3-point one with no compromise on levelness and downtime dropped by 70–80%[1].

Turn the leveling wheel as guided on the touchscreen, and the bed is leveled for tip-top first-layer adhesion.
Easily-managed Z offset calibration.
Using electrical conduction, J1 can calculate the distances between the hot ends and the heated bed. Thus, we were able to cut the step of moving the calibration card back and forth while adjusting the Z offset. Simply turn the thumb wheel as guided on the touchscreen and you are now the Z offset calibration guru!

Aluminum alloy frame.
J1s inherits Snapmaker's iconic all-metal design which users highly value for its rigidity and durability.

Advanced extruder design.

Extruders are redesigned to deliver a superb performance consistently with demanding, advanced materials. Print high-quality projects that meet the structural and functional demands of various engineering applications with little fuss.
300°C Hot Ends
300°C maximum nozzle temperature comes in handy when you print with high-temperature filaments, like nylon, reinforced nylon, and PC. With silicone hot end socks preventing heat loss, filaments melting and heating up are much faster. Anti-clogging designs make the flow as smooth as possible.
Dual direct drive
Excellent extrusion accuracy that aids in the extrusion of flexible filaments, along with the high responsiveness of dual direct drives to make deposition faster, smoother, and more accurately controlled. It is built in with a filament sensor to inform you and pause the print job in the case of filament runout, nozzle clogging, and other abnormalities that fail filament loading.
Compact extrusion path
The compact extrusion path of a unique design allows you to print seamlessly with TPU and many other flexible materials.
Enclosed space
It provides stable ambient conditions to facilitate the consistently reliable performance of high-temperature materials. For instance, it keeps ABS and many other materials from warping.
Engineering applications on J1s.
Flexible and liable to under-extrusion, and therefore requires accurate control of extrusion and heat dissipation.
Including nylon, PA-CF (Polyamide-Carbon Fiber) and PA-GF (Polyamide-Glass Fiber). Tough and wear-resistant, but require strict conditions of printing temperature and nozzle hardness.
Displays high heat resistance and excellent durability. Prone to warping and shrinkage, thus requires stable ambient conditions, best provided by an enclosed space.
Make anything with everything you need.
