BIQU

What to know about shopping at BIQU

BIQU is the storefront for two sibling brands, and knowing which is which saves time. BIGTREETECH, in red, makes the electronics — mainboards, LCD screens, stepper drivers and expansion modules. BIQU, in blue, sells the printers, extruders, hotends, build plates and filament. Both come from the same company, so a BIGTREETECH board and a BIQU hotend are designed to work together rather than merely coexist.

The catalog is built around upgrading a printer you already own rather than replacing it. Control boards are the core line, and the EZ series of boards and drivers plus the CB1 core board for Klipper are the parts that come up most often. Printer-specific sections cover Bambu Lab, Voron, Creality and Snapmaker, CHAOTICLAB handles Voron CNC parts, and MOONS', LDO and E3D components sit alongside the own-brand range.

Two things are worth checking before ordering. Board compatibility is not universal — a mainboard has to suit your printer's motion system, driver type and firmware, so confirm the model against your machine rather than buying on price alone. And many listings are variant-based: the same printer or build plate appears in several configurations, with warehouse and plug options differing between them, so read the variant you have actually selected at checkout.

Savings come from the store's own mechanics rather than from codes. Shipping is free over $59 at the time of writing — a single board rarely clears that, but a board plus a hotend or a few filament spools will, so consolidating an upgrade into one order avoids paying shipping twice. Flash Sale and New Arrival collections are worth a look first, and since upgrade parts are inexpensive next to a complete printer, the larger saving is usually in choosing to upgrade rather than replace.
