Polymaker PETG Filament 1.75mm Army Green 1kg: problems, parts and running costs

Checked: 2026-10-23

Summary

Polymaker PETG is a 1.75 mm, 1 kg high-flow PETG sold under an Army Green listing that does not clearly match an official PETG color named Army Green. Owners most often report moisture-related stringing and surface defects, heat deformation near the rated heat-deflection temperature, color and batch variation, and occasional cardboard-spool feeding problems. A confirmed new-formula roll is a fair buy at $19.99/kg or less, while running cost is driven by consumed kilograms rather than by time.

Common problems and fixes

Moisture-induced stringing, popping, rough surfaces or weak layers — PETG absorbs moisture in storage and can need drying even from a recently opened pack; dry per the manufacturer’s cycle and store dry. Warranty and returns are handled case by case through support for defective or incorrect opened rolls. [3][16][10]
Surface pits and zits after drying — reported in a November 2025 thread on new Polymaker PETG; one user improved surfaces by moving retraction from about 1 mm toward 0.4 mm and lowering nozzle temperature to 245 C. A separate August 2026 user reported persistent bubbles on silver even after extensive drying. Treat this as a single-printer anecdote, not a universal setting. [6][7]
Thermal deformation near the heat-deflection temperature — a March 2026 owner reported PETG High Speed accessories warping after eight hours at 65 C, consistent with the TDS value of 65 C at 1.8 MPa. Keep parts and storage away from hot cars, dryer hardware and loads near the rated HDT. [2][8]
Color and batch variation — a new-formula Dark Green buyer reported changed gloss, a muted brownish shade, different flow and support friction; the manufacturer replied that replacement and QC investigation were appropriate. The official US PETG choices list Dark Green #223622 and Green, not a PETG named Army Green, so confirm formula and shade on the packaging and UPC before reordering. [4][18]
Cardboard spool edge damage and AMS feeding problems — a February 2026 owner reported edge damage and AMS problems, while others reported trouble-free use; hardened edges reduce but do not eliminate the risk. Check spool condition and feeder clearance before printing. [9][17]

Parts and consumables

1 kg PETG filament roll (no verified part number or UPC for the Army Green listing) — $19.99 direct or $25.99 at Partsbuilt; replace when consumed. [4][5]
PolyDryer dryer plus storage box (SKU PX01002_A) — $79.99; buy once if not already equipped, no regular replacement interval documented. [15]
No proprietary nozzle, cartridge or filter — none is specified for ordinary non-filled PETG. [2][3]

Yearly running cost

Running cost scales with printed volume, not with time. Illustrative annual material spend at the checked $19.99-$25.99 per kg references: 1 kg/year = $19.99-$25.99, 3 kg/year = $59.97-$77.97, 5 kg/year = $99.95-$129.95. This covers filament only, assumes purchased kilograms are used, and excludes waste and supports, shipping, sales tax, printer depreciation, electricity, dryer operation and the optional $79.99 dryer. Drying takes about six hours per manufacturer cycle (55 C per TDS v2.0, 60 C per the product page and Wiki); no defensible annual electricity estimate is possible without the dryer model, power consumption and number of cycles.

When it is a good buy

Good buy at $19.99 or less per kg for a confirmed new-formula Dark Green or Army Green-equivalent roll from a reliable retailer, before unusual shipping charges. Poor buy above $25.99/kg unless a specific Polymaker shade or performance characteristic is essential. Alternatives at lower cost: ELEGOO Rapid PETG at $13.99/kg from ELEGOO’s US shop (October 2026) for ordinary functional PETG; ELEGOO PETG Pro at $13.99/kg with an Olive Green option when a muted green is the goal; Bambu Lab PETG Basic 1 kg at $13.99 via NEX3D with refill and spool choices for buyers with reusable spools. Shipping thresholds differ: Polymaker advertises free US economy shipping over $49, ELEGOO over $50; verify checkout for a single roll. [4][5][12][13][14]
