3Dfilamenta say they’ve teamed up with CBD-Tech, a Chinese developer of 3D printer motherboards, to market the latter company’s products overseas.

Image 12Sinh Phu of 3Dfilamenta says these motherboards have been on the Chinese market for the last six months and, according to CBD-Tech, more than 1,000 have been sold in China.

The companies are taking on various open source devices that use the AVR chipset, and they say that chipset lacks the necessary computing power to handle 3D printing tasks with the highest efficiency.

The Chitu motherboard is the first 3D printer motherboard from CBD-Tech, and it’s equipped with a 32-bit, high-speed ARM chipset – STM32F103ZET6 – which is both fast and allows for print outcomes that retain detail even if print speed is increased.

Image 13The Chitu motherboard takes advantage of what the companies call “self-developed firmware” which includes all the advantages of open source firmware.

Using an SD file configuration which can be updated easily and quickly, the motherboard runs one set of firmware for XYZ (cube) printers and another for delta-style printers.

CDB-Tech says the board is compatible with most machines, and the Chitu V3.1 motherboard is equipped with a color touchscreen which features a simple, clean interface.

The highly sensitive touchscreen also handles bilingual setups through a single language key.

Image 16Chitu firmware is optimized, says the company, “to make very beautiful, pure round prints with no edges.”

Optimized PID parameters in the firmware, a major series of analysis and testing data sets have been stored, and these ensure the stability of the board’s operating temperature.

As an added bonus, CBD-Tech says the Chitu motherboard also supports breakpoints, and that means you can print – and then pause – during the middle of a job, save the position of the printhead, turn off the power, and then resume your print the next day with the heads in the exact same position you left them.

The boards retail from $68.59 for an “A” type to $93.56 for the “H” type.

The Chitu V3.1 can be purchased through 3Dfilamenta, the sole outlet for overseas sales.

Most consumer level 3D printers are driven by open source electronics, do you think this Chinese offering includes enough features to make it attractive to builders? Let us know in the Chitu V3.1 3D Printer Motherboard forum thread on 3DPB.com.
