Bambu Lab PETG HF vs ELEGOO Rapid PETG

Who this comparison is for

This page is for anyone choosing between these two specific spools: Bambu Lab PETG HF in Gray (33101) with spool, and ELEGOO Rapid PETG in Black (ELEGOO SKU SPUS-EL-PTG-101), both 1.75 mm and 1 kg. ELEGOO also sells a separate product it calls PETG HF, which isn't covered here, so check the listing says Rapid PETG. If you're still deciding whether PETG is the right material, start with PLA vs PETG, and for more brands, see the PETG filament shortlist. If you're also weighing Rapid PETG against Creality's fast PETG, see Creality Hyper PETG vs ELEGOO Rapid PETG.

How we compared them

This is a research-based comparison. Every figure below comes from the makers' own data sheet, product pages, and wikis, listed in the sources. We haven't tested either filament, so nothing here is a measured result of ours. Where a maker describes its own product, such as "bids farewell to oozing and clumping" or "No Clogging & No Bubbles," we label it as the maker's claim.

We only put numbers side by side where both makers publish the same kind of value under the same named test standard. ELEGOO's product page doesn't name any test standard or specimen conditions, so its strength and heat figures stay out of a head-to-head table.

Side-by-side specs

Temperatures, build plate, and enclosure

The bed ranges match at 65–75 °C, and both makers recommend glue. The nozzle windows overlap at 240–260 °C, but ELEGOO's runs 10 °C higher at the top, to 270 °C, so check your hotend's limit before you use the top of its range. Bambu's filament guide lists PETG HF on its Smooth PEI, Textured PEI, and Engineering plates at 60–80 °C, not on the Cool Plate, and says to let the plate cool fully before removing a print.

On enclosures, the makers' guidance differs:

• Bambu's data sheet lists a 35–50 °C chamber.
• Bambu's filament guide says PETG HF prints on open-frame and enclosed printers, while recommending an enclosed printer for PETG so low room temperatures don't weaken the bond between layers. The same guide recommends removing the top glass cover of an enclosed printer when the bed is above 70 °C for PETG HF, so excess chamber heat doesn't soften the filament in the extruder.
• ELEGOO lists a 25–50 °C chamber and says enclosed printing is "Not Required."

Speed and flow: maker claims on different bases

This is where both makers put the emphasis, and neither figure is a measured race.

• Bambu Lab PETG HF. The data sheet gives a printing speed below 300 mm/s. The store page says "Twice as fast as standard PETG" and adds that "achieving this speed is highly dependent on model size and geometry." Bambu printed its test specimens at 200 mm/s. It doesn't publish a volumetric flow figure for the filament.
• ELEGOO Rapid PETG. The specifications give a printing speed below 600 mm/s, the features say it "supports high-speed printing of up to 600mm/s," and a feature panel on the same page gives "30-600mm/s." ELEGOO says it has "excellent flow characteristics" but doesn't state a nozzle, line width, layer height, or volumetric flow behind the figure.

Neither maker defines its speed the same way, so read these as each maker's ceiling, not as a comparison. In practice your printer's hotend and the slicer's volumetric flow limit usually decide how fast PETG can go.

On print quality, Bambu claims PETG HF "bids farewell to oozing and clumping" and achieves good results "without fine-tuning parameters." ELEGOO claims "low warping, shrinkage, and deformation" and, for the spool, "No Clogging & No Bubbles" because each spool is dried and vacuum-sealed with desiccant. These are the makers' claims, with no test data on their pages.

Finish

Bambu's data sheet describes "the new matte finish" that smooths "uneven gloss during speed transitions," and its store page promises "consistent gloss at any printing speed." ELEGOO's page doesn't describe the finish of Rapid PETG.

Strength and heat figures: not on the same standard

Bambu's data sheet names its standards, including ISO 75 for heat deflection, ISO 306 for Vicat softening, ISO 527 for tensile, ISO 178 for bending, and ISO 179 for impact. Its specimens were printed at 255 °C on a 70 °C bed at 200 mm/s with 100% infill, then annealed and dried at 75 °C for 8 hours before testing, though Bambu doesn't recommend annealing PETG HF prints. ELEGOO lists similar properties but names no test standard and says nothing about how its specimens were printed. Without a shared standard and setup, we don't put these in a head-to-head table.

For heat, each maker gives a figure at 0.45 MPa: 69 °C for Bambu, tested to ISO 75, and 72 °C for ELEGOO, with no standard named. Bambu also gives 62 °C at 1.8 MPa, which ELEGOO doesn't publish. At 0.45 MPa, both sit around the high 60s to low 70s °C, and Bambu's 1.8 MPa figure is lower, so neither suits parts near engines, heaters, or a hot car dashboard.

We left out tensile, bending, elongation, impact, density, and melt index figures. Both makers publish them, but only Bambu names standards and specimen conditions, and ELEGOO's impact figure doesn't say whether the bar was notched. Bambu gives both an X-Y impact figure and a separate notched one.

Spools and the AMS

This listing of PETG HF comes on Bambu's ABS spool, 200 mm across and 67 mm high, rated to 70 °C. That fits the AMS's documented spool range of 50–68 mm wide and 197–202 mm in diameter. Bambu says "All printing parameters are embedded in RFID, which can be read through our AMS," its store page lists PETG HF as "All AMS Series Compatible," and its filament guide lists it as compatible with the AMS and AMS lite. Bambu also sells PETG HF as a refill without a spool, which needs a reusable spool.

Rapid PETG ships on an "eco-friendly cardboard" spool weighing 154 ± 10 g empty, and ELEGOO doesn't publish its dimensions. ELEGOO offers a printable filament ring, which it says reduces delamination and adapts the spool to the AMS, "because AMS will rub the bottom paper tray, causing the paper tray to easily delaminate." Bambu's own AMS notes "highly recommend" plastic spools that fit correctly and "strongly advise" a spool adapter or adapter ring for cardboard spools, to reduce slippage and debris. Our AMS filament compatibility guide covers spool sizes and adapters.

Drying and storage

Both makers say to dry before use and to keep the spool sealed with desiccant at or below 20% RH.

• Bambu Lab PETG HF. The data sheet gives 65 °C for 8 hours in a blast drying oven, or 75–85 °C for 12 hours on an X1 Series heatbed. Bambu's filament guide gives 65 °C for 12 hours in an AMS 2 Pro or AMS HT, and marks drying before use and desiccant during use as "Required." The store page says PETG HF "must be dried before use and remain moisture-free during the printing process, especially for longer print times (over 6 hours)." The heatbed figure is above the 70 °C rating Bambu gives its ABS spool, so follow Bambu's drying instructions for how to set that up.
• ELEGOO Rapid PETG. The product page gives 60 ± 5 °C for 8 hours, marks drying before use as "Required," and says each spool is dried before packing and vacuum-sealed with desiccant. ELEGOO doesn't publish a temperature rating for its cardboard spool, so check your dryer's documentation.

Our filament dryer vs dry box guide covers the options.

What each maker says it's for

• Bambu Lab PETG HF. Bambu calls it "The PETG that prints as effortlessly as PLA," "Ready for Outdoor Use," with resistance to water, UV, and temperatures. Its examples include planter pots, bird cages, watering cans, automotive parts, and outdoor toys.
• ELEGOO Rapid PETG. ELEGOO says it balances PLA and ABS, "easy to print like PLA while offering a similar impact and tensile strength to ABS," with "increased rigidity" for structural prints and weather resistance for indoor or outdoor use. It also claims "excellent thermal formability," so prints can be heat-formed or bent after printing.

Discontinued: Bambu Lab's US store says PETG HF "is discontinued and will not be restocked once sold out" and points buyers to its PETG Basic. See Bambu PETG Basic vs Polymaker PETG for that spool.

Verdict: which should you buy?

Choose Bambu Lab PETG HF if…

• You print on a Bambu Lab printer and want the AMS to read settings from the spool's RFID tag.
• You want a plastic spool that matches the AMS's documented spool size without an adapter or printed ring.
• You want a data sheet with named test standards, retraction settings, and four listed nozzle sizes.

Choose ELEGOO Rapid PETG if…

• Your hotend handles 270 °C comfortably and you want the maker with the higher stated speed ceiling.
• You print on a non-Bambu printer, where an RFID tag doesn't matter.
• You're happy to print ELEGOO's filament ring, or use an adapter, if you feed the cardboard spool through an AMS.

Safety and limits

How this page was checked

Every temperature, speed, drying setting, spool detail, and test figure above comes from the manufacturer documents in the sources section, retrieved on 2026-10-09. We haven't printed with either filament for this page, so nothing here is a measured result of ours. Bambu's data sheet tables extract out of line with their labels, so we read each value from a row-by-row extraction and checked it against the rendered table. ELEGOO's specification table sits in the product page's embedded data rather than its visible text, and we read the values from there. Bambu's drying wiki doesn't list PETG HF by name (its row covers PETG and PETG-CF), so we've used its filament guide, which does, for the AMS 2 Pro and AMS HT figures. Values vary by color and revision, so check the current data for your spool. Read more in our editorial standards and affiliate disclosure.
