Bambu Lab has quietly discontinued PETG HF across most colors, replacing it with a reformulated PETG Basic that launched in March 2026. Users still mid-project should stock up — HF inventory at third-party sellers is clearing fast.
Bambu Lab’s high-speed PETG variant — PETG HF — has been phased out of the official lineup and is no longer restocked in most color options. The company’s replacement is PETG Basic, which returned in March 2026 with a reformulated compound Bambu says addresses the two main complaints about the original: moisture sensitivity and stringing at high speeds.
What Changed in PETG Basic 2026
The reformulated PETG Basic is not the same product that shipped before PETG HF launched. Bambu has updated the compound to print more cleanly at standard Bambu speeds (250–350mm/s on P-series), with reduced tendency to absorb ambient humidity — one of the most common complaints in the r/BambuLab community about PETG on AMS-equipped printers.
Bambu has not published a detailed technical breakdown of the formulation change, but community reports from MakerWorld and the Bambu Lab Community Forum indicate the new PETG Basic behaves closer to PETG HF than the original PETG Basic did, at a lower price point per spool.
Is PETG Basic a Drop-In Replacement for PETG HF?
Not quite. Community research suggests PETG Basic 2026 performs well at standard Bambu speeds but doesn’t fully match PETG HF’s behavior at maximum print speeds (above 350mm/s). Users running aggressive speed profiles on X1C or P2S hardware should plan for a re-tuning session rather than a direct profile swap.
Temperature appears to be the most sensitive variable: several users report that PETG Basic 2026 runs cleanly at 240–245°C on the same profiles where PETG HF required 245–250°C. Reducing temperature slightly while keeping speed the same seems to be the most common successful adjustment.
What Happens to Existing PETG HF Stock
Bambu is not recalling or discontinuing available inventory — once current stock is sold, it won’t be replenished. Third-party retailers (Amazon, Matterhackers, Printed Solid in North America; a number of EU distributors) may still have HF stock in select colors for several weeks. If color-matching for an ongoing project is critical, buy what you need now.
What This Means for Your Printing
If you use Bambu PETG for most of your prints: switch to PETG Basic 2026 and run a temperature tower. Most users land on 240–243°C with minimal other changes. If you push your printer above 350mm/s consistently, expect a few test prints before dialing in your profile.
