BIQU Discount Codes & 3D Printer Deals

BIQU is a manufacturer that sells direct, and that shapes what you find on the site. It is not a general electronics retailer that happens to stock 3D printing parts — the company designs and produces the boards, hotends and printers it lists, which is why the catalog goes deep on components and comparatively shallow on everything else.

If you have upgraded a printer in the last few years you have probably already used their hardware without buying it here. BIGTREETECH control boards are a common sight in Voron and Ender builds, and they are BIQU's own. Understanding how the two brand names relate is the first step to navigating the store efficiently.

BIGTREETECH or BIQU: telling the two brands apart

The site carries both names and the split is consistent. According to BIQU's about page, BIGTREETECH uses a red colorway and covers the electronics — mainboards, display screens, driver boards and expansion modules. BIQU uses blue and covers the physical hardware — printers, extruders, hotends, build plates and filament.

A third name, CHAOTICLAB, appears on Voron-specific CNC parts. Alongside the own-brand ranges the store also resells components from MOONS', LDO and E3D, which matters if you are sourcing a full build and would rather place one order than four.

The practical upshot: if you are shopping for a board, screen or driver, you are looking for BIGTREETECH. If you are shopping for something that moves, heats or gets printed on, you are looking for BIQU.

What BIQU actually sells

The catalog organizes around upgrading a machine you already own. The main groups are control boards, LCD screens, motors and drivers, expansion and module boards, extruders and hotends, build plates, and filament.

Two product lines come up more than the rest. The brand states that it developed the EZ series of motherboards and drivers, and the CB1 core board aimed at running Klipper — both positioned as cost-effective routes into features that were previously the preserve of more expensive hardware. If you are moving a printer to Klipper, that is the part of the range to read first.

There are also printer-specific sections for Bambu Lab, Voron, Creality and Snapmaker machines. These are the most useful way into the store for anyone who knows their printer but not their part numbers.

Choosing a control board without guessing

This is where money gets wasted, so it is worth slowing down. A mainboard is not a universal component. It has to match your printer's motion system, the stepper driver type you intend to run, and the firmware you plan to flash. Buying the highest-specified board in the range does not help if it does not fit the machine.

Work in this order. Start from the printer-specific collection for your machine rather than the general board listing. Confirm the driver situation — some boards ship with drivers integrated, others expect you to add them, and that difference changes the real cost meaningfully. Then check the firmware you intend to run, because a board marketed around Klipper support is a different proposition from one aimed at Marlin.

One further detail specific to this store: many listings are variant-based. The same printer or build plate appears in several configurations, and warehouse location and plug type differ between them. Read the variant you have actually selected before checking out, not the one shown in the first product photo.

Build plates and filament: the cheap upgrades

Boards get the attention, but the two parts most likely to change how your prints actually come out are cheaper than either. Build plates are the first — surface type governs adhesion far more than any slicer setting, and swapping a worn plate is a low-cost fix for a machine that has quietly become unreliable. BIQU lists plates by printer, including sizes for the Bambu Lab machines, which avoids the guesswork of matching dimensions yourself.

Filament is the second, and here the useful move is buying enough of one material to finish a project rather than sampling widely. The store carries its own spools, including a carbon-fiber-reinforced line the brand positions for strength and low warping. Whatever you pick, filament is heavy, so it is also the easiest way to clear a shipping threshold without buying something you did not need.

How to save at BIQU

The most reliable saving here is the shipping threshold, because it is predictable in a way that promotions are not. Free shipping applies over $59 at the time of writing. A single board or one spool of filament frequently sits under that figure, while a board plus a hotend, or two or three spools, clears it comfortably. Grouping an upgrade into one order rather than buying parts as you think of them is worth real money over a year.

Beyond that, the Flash Sale and New Arrival collections are where pricing actually moves, and they turn over often enough to be worth checking before you commit to a full-price part.

The larger saving, though, is a decision rather than a discount. Upgrade parts are cheap relative to a complete printer, so the question worth asking before you spend anything is whether a new board and hotend would get you what you actually want from a machine you already own. For a printer whose frame and motion hardware are sound, the answer is usually yes — and that is a bigger difference to your total spend than any coupon code would make.

For the current state of play, our BIQU store page tracks deals as they become available, and the wider electronics category covers the rest of our tech coverage.

Is BIQU worth buying from directly?

If you need components, the direct route makes sense — you are buying from the manufacturer, the own-brand parts are designed to work with each other, and the printer-specific organization saves genuine time over cross-referencing part numbers on a marketplace. The brand states it has served more than three million customers across over a hundred countries, and the range reflects that scale in its depth rather than its breadth.

Where it makes less sense is if you want a single finished appliance and no involvement in how it works. This is a store for people who are comfortable opening a printer. If that is you, it is one of the more coherent places to buy parts; if it is not, a complete machine from a general retailer will serve you better.
