Creality Hyper PETG Filament 1.75 mm 1 kg (Transparent): problems, parts and running costs

Checked: 2026-10-17

Summary

Owners most often hit extruder-gear jamming traced to a printer profile that leaves the chamber fan disabled, plus one unreproduced case of ~30 failed prints across two cardboard spools [11][12]. The practical extra cost of running PETG is a dryer or dry box; Creality sells a Filament Storage Box and a Space Pi Filament Dryer Plus on its AU store [18]. At $18.99 per 1 kg spool (Creality US store, October 2026) it is a reasonable PETG buy for utility prints [6].

Common problems and fixes

Extruder-gear jamming on K2 Plus — a K2 Plus owner documented PETG jamming in the extruder gears after about 15 minutes; root cause was the chamber fan (Fan 1) disabled in the default Hyper PETG profile, letting chamber heat soften the filament near its ~75 °C softening point. Enabling Fan 1 at 100% solved it across a 4.5-hour print [11].
~30 failed prints with no fix found — a K2 SE owner using two Hyper PETG cardboard spools reported filament that “jams in between the extruder gears and looks crinkled”, with no consistent fix across temperature (235-255 °C), speed, flow and drying (65 °C / 6 h) changes [12].
Nozzle gumming — a Reddit r/Creality_k2 thread on PETG and Hyper PETG printing problems reported gumming at the nozzle resolved only by printing at 290 °C with an external spool [14].
Moisture-related stringing and poor adhesion — moisture is the first-order failure variable: GoodPrints advises checking moisture before rewriting retraction, cooling or temperature when a fresh spool prints cleanly but degrades after storage [5].
Conflicting factory temperatures — Creality’s own pages disagree on bed temperature (45 °C on store pages vs 70-80 °C on the data sheet) and nozzle range (190-260 °C vs 220-260 °C); owner practice clusters at 235-255 °C nozzle and 70-80 °C bed [1][3].
Cardboard spools and CFS compatibility — some Hyper PETG stock ships on cardboard spools, which Creality’s CFS guidance does not recommend for its feed paths; verify spool type before CFS use [5][12].

Parts and consumables

Filament itself is the only consumable; the transparent 1 kg spool is SKU 3301030042, EAN 6971636401964 [8][9]. Warranty: Creality US store pages state “Up to 12-Month Warranty” and “14-Day Return & Refund” [7][18].

Yearly running cost

Not enough data. The research lists only one practical recurring cost: drying equipment (dryer box or filament dryer) for PETG storage [18]. No electricity, subscription or per-print cost figures were reported for this filament.

When it is a good buy

At $18.99 per 1 kg spool (Creality US store, down from $25.99, October 2026) it is good value for utility PETG when the buyer already has drying capability and a hotend that can use the high-flow formulation; the 300 mm/s headline needs roughly 27-60 mm³/s, beyond many stock hotends [5][6]. Other stores at check time: 3DJake (EU) at $21.26 excluding VAT for transparent 1 kg (October 2026) [9], FilamentTrackHub (US) at $18.99 plus $3.99 shipping (checked 2026-10-11) [8], and Creality’s EU store at €29.99 down from €44.99 [19]. At $21-25 it is fair and worth comparing against Creality’s own CR-PETG at $12.99-14.99 on sale or Soleyin Basic PETG at $11.99 [6]. Above $25 it is weak unless the transparent colorway or Creality CFS/RFID ecosystem is specifically required [6]. Overture High Speed PETG is a direct high-speed PETG competitor at 230-260 °C nozzle, 65-70 °C bed, under 300 mm/s and ±0.02 mm tolerance, with SDS/TDS documents [24].
