Prusament ASA Natural 1.75mm 800g 3D Printer Alternatives: 6 Similar Picks Compared

How these ASA options differ

iSANMATE 1.75mm 12kg ASA Filament

The iSANMATE ASA filament offers a 12kg spool, which is significantly larger than the 800g Prusament spool. This bulk size reduces spool changes for high-volume users. It maintains the standard 1.75mm diameter and includes a dimensional accuracy of plus or minus 0.02mm. You get more material for the same print tasks. The trade-off is the massive weight and size, which may not fit smaller storage spaces. It is best for users with enclosed printers who need durable outdoor parts without frequent reloading. The Prusament option provides a smaller, more manageable spool with verified manufacturing data, but iSANMATE is better for minimizing downtime during long production runs.

FLASHFORGE 1.75mm ASA Filament

The FLASHFORGE ASA filament in black matches the 1.75mm diameter of the Prusament option but comes in a 1kg spool. It shares the same plus or minus 0.02mm dimensional accuracy, ensuring precise layer placement. This consistency helps reduce print failures similar to the Prusament product. However, it is only available in black, whereas the Prusament option offers a natural color and other variants. The weight is identical at 2.2 pounds. This choice suits users who prioritize UV-resistant functional parts in a single color. It is a solid alternative if you need a slightly larger spool than the 800g Prusament but do not require the bulk of the 12kg options. The focus is on stability and accuracy for outdoor applications.

FLASHFORGE 1.75mm White ASA Filament

The FLASHFORGE white ASA filament provides the same 1.75mm diameter and plus or minus 0.02mm accuracy as the Prusament option. It is designed for durable, UV-stable functional prints. The main difference is the color; this option is white, while the Prusament is natural. Both weigh 2.2 pounds, offering comparable handling. This filament is ideal for users who need weather-resistant parts in a light color. It sacrifices the color variety of the Prusament line for a specific aesthetic. The performance in terms of precision and heat resistance is comparable. If you require white functional components for outdoor use, this is a direct alternative. It does not offer the QR code verification found on Prusament spools, relying instead on standard accuracy metrics for quality assurance.

R QIDI Technology 1.75mm ASA Filament

The QIDI Technology ASA filament in blue matches the 1.75mm diameter of the Prusament option. It is designed for outdoor functional parts requiring UV and heat resistance. The weight is also 2.2 pounds, similar to the Prusament spool. This product is best for users who need durable components in a blue color. It lacks the specific manufacturing data verification via QR code that Prusament provides. The focus is on thermal stability for mechanical applications. If you prefer a colored functional part, this is a robust choice. It fits users with enclosed printers who need weather-resistant prints. The trade-off is the lack of color options compared to the Prusament line, but it delivers comparable durability for technical applications.

Frucindra 1.75mm White ASA Filament 2kg Bundle

The Frucindra ASA filament bundle includes 2kg of white filament, which is larger than the 800g Prusament spool. It is labeled as tough resin type, suggesting enhanced durability for outdoor projects. The diameter is 1.75mm, matching the standard. The weight listed is 0.35 ounces, which appears to be a data error, but the bundle implies more material than the single 800g spool. This option is best for makers needing tough, UV-stable functional components in white. It sacrifices the precise manufacturing verification of Prusament for a bundled value. If you require white parts and want more material, this is a viable alternative. The larger quantity reduces spool changes, similar to the iSANMATE option, but in a smaller package than the 12kg bulk spool.

ELEGOO Glow in the Dark Green PLA Filament (1.75mm, 1kg)

The ELEGOO Glow in the Dark Green PLA filament differs significantly in material. It is PLA, not ASA, so it lacks UV and heat resistance. It is designed for decorative prints with a glow effect. The diameter is 1.75mm, and it weighs 2.2 pounds. This option is best for visual accents rather than functional outdoor parts. It sacrifices industrial durability for aesthetic appeal. If you need glowing decorative items, this is a unique choice. It does not compete with the Prusament ASA for technical applications. The material properties are entirely different, making it unsuitable for outdoor or functional use. It is a niche alternative for makers prioritizing glow effects over strength and weather resistance.
