BIQU

BIQU Filament

Specialty flexible filament from the team behind BIGTREETECH.

BIQU is the filament and printer brand of Shenzhen BIQU Technology, the company behind BIGTREETECH mainboards. We stock its two specialty filaments, the kind the big brands don't make: PLA-HR for bouncy, airless parts like printed basketballs, and MorPhlex, a TPU that prints firm and cures soft. Both run on Bambu Lab printers; feed MorPhlex from an external spool holder, not the AMS.

Strengths and trade-offs

Where it wins

MorPhlex prints like a firm 90A TPU and cures to a soft 75A, so soft parts stop jamming
PLA-HR absorbs and returns impact: built for airless balls and toys that take a beating
Backed by the company behind BIGTREETECH electronics

Worth knowing

Two specialty filaments, not an everyday PLA or PETG line
Keep MorPhlex out of the AMS: feed it from an external spool holder
Flexible filament absorbs moisture fast, so dry it before you print

Line	Nozzle	Use it for
PLA-HR	215–225°C	High-resilience PLA for airless basketballs and impact-tough parts
MorPhlex TPU	225–260°C	Shoes, insoles and soft grips: prints at 90A, cures to 75A

Who they are

BIQU and BIGTREETECH belong to the same Shenzhen company: BIGTREETECH makes mainboards, drivers and displays, BIQU makes printers, accessories and filament. If you've upgraded a printer's electronics, there's a good chance you've used their work.

The filament line is small on purpose. PLA-HR is a high-resilience PLA built to bounce like a basketball without air; a printed ball weighs about 605 to 610 g. MorPhlex fixes the classic soft-TPU problem: it feeds into the hotend as a firm 90A, so the extruder can grip it, then cures to a soft 75A after printing. That makes shoes, insoles and grips printable without the jams true 75A filament causes.

Frequently asked

What makes MorPhlex different from regular TPU?

It feeds into the hotend as a firm 90A TPU, so it prints like an easy flexible, then cures to a soft 75A once the print cools. You get soft, comfortable parts without the jams true 75A filament causes.

Is BIQU filament related to BigTreeTech?

Yes — BIQU and BigTreeTech are sister brands under the same Shenzhen company. BigTreeTech handles mainboards and electronics; BIQU handles printers, accessories, and filament.

Is PLA-HR actually flexible like TPU?

It's high-rebound and impact-resistant — springier than standard PLA, but firmer than TPU. It's built for bouncy, airless parts like printed balls, not as a general flex-filament substitute.

Does BIQU make standard PLA or PETG?

Not currently — the catalog here is specialty flexible filament only. For everyday PLA or PETG, see our Bambu Lab or Creality lines.
