Кратко

PETG-проволока высокого распыления в блестящем цвете Galaxy Dark Grey, ориентированная на функциональные детали, наружное использование и сборки для косплея. Проверьте сопло и хранение перед покупкой: цвета Galaxy требуют сопла 0,4 мм или больше, а материал гигроскопичен, поэтому сушите перед печатью.

Сильные стороны

Prints smoothly with minimal stringing when kept dry.
Excellent layer adhesion reported by owners.
Galaxy glitter gives a premium look and hides layer lines.
Easy to print with little or no setting adjustment.
AMS compatible, with hardened spool edges.

Слабые стороны

Hygroscopic: stringing and surface defects if not dried; popping or cracking when wet.
One owner reports a formula change that removed the metallic finish and altered flow, affecting tuned prints.
Some users report lower temperature resistance versus the older formula.
Galaxy colors require a 0.4 mm or larger nozzle to avoid clogs.
Batch-to-batch color and finish variation is possible.
Diameter tolerance is not stated by the manufacturer.

Параметры печати и настройка

Nozzle 240-260 C, bed 60-70 C, up to 300 mm/s with a standard nozzle and over 500 mm/s with a high-flow nozzle, cooling 20-60%, retraction 1-3 mm at 20-40 mm/s. No enclosure is needed, and PC or textured PEI is the recommended build surface. Galaxy Dark Grey needs a 0.4 mm or larger nozzle. The spool ships vacuum-sealed in a resealable bag.

Сушка, хранение и затраты на эксплуатацию

The material is hygroscopic, so dry it at 60 C for 6 h, or 65 C for 4 h, if it has been exposed, and store it sealed; the manufacturer recommends a PolyBox or PolyDryer. Ownership costs are drying time and electricity, desiccant or storage, possible nozzle replacement for glitter colors, and a build surface; there is no subscription or lock-in. The manufacturer shop lists Polymaker PETG Galaxy Dark Grey, new formula, 1 kg, at $24.99. Base Polymaker PETG is listed at $18.99, with the range running from $18.99 to $79.99 by color and weight. Bulk discounts on the shop: 15% off four spools, 25% off six, 35% off ten or more, and 10% off a first purchase.

Отделка, цвет и изменение формулы

Owner feedback on the manufacturer site is mostly positive on printability and layer adhesion. A minority reports a formula change that altered finish and flow: one owner describes the metallic finish disappearing on a later spool, leaving a flat, muted color, with flow differences where old and new filament meet on tuned prints. Some users report lower temperature resistance versus the older formula, though the stated heat deflection temperature is unchanged. Color appearance may vary by batch. No independent instrumented test of this exact filament was found; the TDS values are manufacturer-reported typical values not intended for design specifications.

The source’s value thresholds place under about $20/kg as strong value for a high-flow PETG with documented properties, $20-30/kg as fair value where color effect, print speed, and drying needs decide it, and above $30/kg as weak value unless the Galaxy color effect or specific mechanical properties are required. Buyers needing only basic PETG may find lower-cost options; buyers needing guaranteed batch consistency should note the reported formula change.
