  • • Target User: this is NOT a novice-friendly kit

    This is a kit with plenty rooms of customization for your liking and might take you 1~3 working days of assembly and tuning.

    This printer won't be friendly if you're new to FDM 3D printing. To make it print you need all these knowledge and skills which result in steep learning curve: common sense of mechanical skill and material strength, basic electronics, knowledge of slicing, machine tuning and maintenance.

    You can use your preferred slicer and firmware parameters. Please note the performance of printer might differ depending on your assembly and tuning. With Volcano hotend and proper tuning, conservatively you'll get decent prints over 100mm/s.

    Please also check the latest Assembly Manual on SK-Tank GitHub repository and see if you're OK with the whole assembly. Also welcome join SecKit group and check owners' sharing. Happy 3D printing!

  • • Shipping speed won't be that fast

    Thank for all your liking but I'm sorry SecKit is still a 1-man business doing everything so shipping won't be that fast. Kits will be sent in groups of 10~20 orders because of my limited stamina and warehouse size and hope I can deliver a group each 1~2 weeks.

    Please understand sometimes there will be unexpected surprises such as suppliers sending wrong compnents, logistics or custom clearance problem. I'll do it as soon as possible. 😅🙏

    1. Customize your options listed below.
    2. Pay with your credit card. A 3D-Secure transaction enabled card is preferred.
    3. (If out of stock) Factory starts making components.
    4. SecKit sends the package and tracking number to you.
    Payment service is supported by , a Taiwan payment service provider with PCI DSS Level 1 certified.
Frame + motional components + 3 Z gearbox steppers only. Follow this list and self-source all other electronics and accessories.
All components of a full-function printer. Please configure your options below.
For Full Kits after Apr 5th 2022, MKS Servo42C 1.8° steppers have replaced TMC2225 + LDO 0.9° steppers used in XY. Servo42C's work quietly, cool and VFA free.
Linear Motion
Supplied by a Taiwan distributor assigned by HIWIN. Linear blocks are pre-installed onto rails.
X axis
The aluminum XY joiner, extruder carriage and MGN12 rail weigh about 630g. The X gantry made by aluminum & steel with a similar Coefficient of Thermal Expansion to the frame is more suitable for high temperature printing in an enclosed printer.
The carbon fiber XY joiners, extruder carriage, X back tube and MGN9 rail weigh about 480g, saving about 24% moving weight of the above option. Choose this if you do more fast & low temperature (PLA, PETG, etc) prints and want a minimum ringing effect.
Control Board

Both Klipper or ReprapFirmware are available for SK-Tank and each of them provides a wonderful web interface which allows you to access the full capability of your SK-Tank. Please download firmware configuration files from SK-Tank GitHub repository.

A high quality 8-driver board for running Klipper firmware on a RaspberryPi and access your SK-Tank via a web browser. Note this is the F429 version with 1MB internal flash for RepRapFirmware binary size, not the F446 version with smaller flash size.

A high quality 6-driver board for running Klipper firmware on a RaspberryPi and access your SK-Tank via a web browser. It has an expansion board M5 (not included) if you want more driver slots. If running ReprapFirmware you'll need an extra WIFI module.

Wirelessly access your SK-Tank with Duet Web Control (ReprapFirmware) via a web browser. Follow this manual to setup your RRF on Mellow Fly CDY v3.

A 24V control board with 6+ driver slots is a must.
(2022 Apr) RPi is temporarily disabled because the price has been raised too fast for another 30% in recent 2 months. Can't afford the loss between my listed price and the cost when I'm sourcing it. Please send messages if you still want it and allow me to reply the latest price.
