Polymaker ASA vs Overture ASA

Who this comparison is for

This page is for anyone choosing between these two specific spools: Polymaker ASA in Black (SKU PF01001, formerly sold as PolyLite ASA) and Overture ASA in Black, both 1.75 mm and 1 kg. Polymaker says you may still receive the old PolyLite packaging. If you're still deciding between ABS and ASA, start with our ABS vs ASA guide. For other ASA brands, see the ASA filament shortlist.

How we compared them

This is a research-based comparison. Every figure below comes from the makers' own data sheets, product pages, and wiki, 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 UV resistance or a "Clog-Free formula," we label it as the maker's claim.

We only put numbers side by side where both makers publish the same kind of value. Where they don't, or where the test setups differ, we say so rather than force a comparison.

Side-by-side specs

Temperatures, speed, and build plate

The nozzle windows overlap at 240–260 °C. Polymaker's data sheet starts 10 °C lower, at 230 °C, and Overture's runs 10 °C higher, to 270 °C. Polymaker's own pages differ on the low end:

• Data sheet, wiki, and the product page's specifications panel: 230–260 °C.
• Product page print settings: 240–260 °C.
• Product page printing tips: 240–260 °C "for faster printing or improved layer adhesion."

The bed ranges sit together at the top, 75–95 °C for Polymaker and 70–95 °C for Overture. Check that your hotend's documented maximum covers the range you plan to use.

The speed guidance is the biggest practical difference. Polymaker's data sheet gives 50–200 mm/s, and its wiki gives a maximum volumetric speed of up to 16 mm³/s. Overture's data sheet and product page both give 30–50 mm/s. Neither maker defines its figure the same way, so read these as each maker's guidance, not as a measured race.

On the plate, Overture's data sheet calls for PVA glue on a PA film, PI film, or textured PEI surface. Polymaker lists PC or textured PEI, and its product page says to apply a suitable adhesive as a release layer and let the plate cool before removing the print. Its wiki suggests Magigoo Original if you have adhesion problems.

Enclosure and ventilation

Both makers say to print in an enclosure. Polymaker's data sheet lists the closure chamber as "Needed," and Overture's product page says "Enclosed Printer Required." Bambu Lab's filament guide also groups ASA with materials that "require higher heatbed and chamber temperatures" and recommends an enclosed printer.

Polymaker is the more specific of the two. Its wiki says a non-enclosed printer with a 90 °C bed and a 260 °C nozzle "can handle models smaller than fist size," that bigger prints need an enclosed printer at about 40–50 °C, and that models bigger than about 15–20 cm in any direction need an actively heated chamber of about 70 °C or more. It also suggests heating the plate to 90–100 °C for 10 minutes before printing so the chamber can warm up. Overture doesn't give size or chamber guidance.

An enclosure keeps heat in, but it doesn't deal with fumes. Polymaker's wiki says the smell of ASA is stronger than PLA or PETG, and recommends "proper ventilation and filtration." Overture's FAQ says its ASA "does produce some odor during printing" and advises good ventilation and considering air filtration. Our enclosure planning guide covers heat and exhaust, and the ASA filament shortlist compares the enclosure and ventilation guidance across more brands.

Strength and heat figures: same standards, different specimens

Both data sheets use the same named standards for several properties: ISO 527 for tensile, ISO 178 for bending, ISO 179 for notched Charpy impact, ISO 306 for Vicat, and ISO 1183 for density. The specimens weren't prepared the same way, though. Polymaker printed at 260 °C on a 90 °C bed in a 90 °C environment, with 100% infill, two shells, three top and bottom layers, and the fan off, and doesn't state a print speed. It says its figures come from testing PolyLite ASA (SKU PF01046). Overture printed at 260 °C on an 80 °C bed at 50 mm/s with 100% infill, and conditioned the specimens at room temperature for 24 hours. It doesn't state a chamber temperature. Chamber heat changes how well ASA layers bond, so these are each maker's figures, not a head-to-head.

Polymaker also publishes heat deflection temperatures of 100 °C at 1.8 MPa and 103 °C at 0.45 MPa (ISO 75), a glass transition of 98 °C, and several Z-direction figures: a Young's modulus of 1965 MPa, elongation of 1.65%, and notched impact of 6.7 kJ/m². Overture publishes none of these, so there's nothing to set them against. Don't compare Polymaker's heat deflection figures with Overture's Vicat figure. They're different tests with different loads and pass criteria. On the one heat test both publish, Vicat, the two are about 1 °C apart.

Overture's product page summarizes its data sheet with "Toughness" (the 13.1 kJ/m² impact figure), "Layer Adhesion" (the 33.1 MPa Z tensile figure), and "Elongation," and lists "Stiffness" as N/A even though its data sheet gives a Young's modulus. We used the data sheet.

We left water absorption out. Polymaker gives an equilibrium figure of 0.40% at 23 °C and 70% RH, and Overture gives none.

Weather and UV claims

Both makers sell their ASA for outdoor use, and only one publishes results. Polymaker's wiki and product page FAQ describe its own aging tests. After two years of natural aging, the color change was below 2.5 ΔE, and after accelerated aging at 8000 kJ/m² of irradiation, it was below 5 ΔE with "minimal tensile strength loss." Polymaker says outdoor parts "maintain integrity for a minimum of two years." Those are Polymaker's findings on its own material, not a lifespan for your part.

Overture says its ASA is "specially formulated for maximum UV protection" and describes its colors as fade-resistant, but publishes no aging test. Treat both as maker claims. The test figures above say nothing about outdoor life.

Drying, storage, and spools

Polymaker says ASA has "low moisture uptake," but both makers give drying settings, and Polymaker's pages don't agree with each other.

• Polymaker ASA. The data sheet, wiki, and the product page's specifications panel give 70 °C for 7 hours. The product page's print settings give 70 °C for 6 hours, "Only if the material has absorbed moisture." Its printing tips say 70 °C for 4 hours is "typically sufficient" after brief exposure, and to use the 7-hour setting after extended exposure or when moisture defects appear. We list the data sheet value. Polymaker recommends storing it in a PolyBox or PolyDryer box.
• Overture ASA. The product page and FAQ give 75 °C (167 °F) for 7 hours, and the FAQ warns that longer drying "can lead to the filament becoming brittle." The data sheet gives no drying setting. Overture says every spool is dried for 24 hours and vacuum-sealed in a resealable foil bag, and gives a 1-year shelf life for unopened spools stored properly.

Polymaker ships on a cardboard spool, with 4 mm pressed cardboard faces, and its FAQ says its spools have redesigned edges that "spin great in the AMS." Bambu's own AMS notes "strongly advise" a spool adapter or adapter ring for cardboard spools. Overture doesn't publish its spool's material or dimensions on the product page or data sheet, so check the fit in your feeder or dryer. Polymaker says it doesn't sell refills. See our filament dryer vs dry box guide before drying either spool, and check your dryer's limits for a cardboard spool.

What each maker says it's for

• Polymaker ASA. Polymaker calls it "an advanced alternative to ABS" with improved weather resistance and UV stability, that "prints with settings very similar to ABS," for functional parts, enclosures, and prototypes. It says it can be smoothed with acetone.
• Overture ASA. Overture describes ASA for outdoor use with "exceptional thermal stability," a patented "Clog-Free formula," and compatibility with "nearly all consumer and industrial 3D printers," while also listing an enclosed printer as required.

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. Polymaker's data sheet link still carries a V5.4 file name but now opens version 6.0, and its columns don't extract in line with their row labels, so we matched each value to its row and its test method by position. Polymaker's product page disagrees with its data sheet on nozzle temperature and drying, and we've said which we followed. Values vary by color and revision, so check the current data sheet for your spool. Read more in our editorial standards and affiliate disclosure.
