Prusament ASA 1.75mm 800g (NFC)

Summary Prusament is a premium-grade material made by the same people who build the printers. Every spool is manufactured in-house with consistent color and high diameter precision. You can verify it yourself, down to the last meter. Description Why To Choose Prusament Guaranteed Color Consistency Every Prusament color is formulated and locked to a documented spectroscopic recipe. Prusa test every batch against the standard before it ships. The result: if you run out mid-project and order a second spool, the colors will match perfectly. Precise Manufacturing & Strict Quality Control Their diameter tolerance is the maximum limit, not an average: when they say the diameter tolerance is ±0.04 mm, the real numbers are much lower. Prusa continuously measure and record diameter and ovality across the full length of every spool and publish the actual data. High Quality You Can Check Yourself Every Prusament spool comes with the actual measured data from manufacturing: diameter readings along the entire length, weight, and ovality. Prusa is the only filament manufacturer in the world that does this. Perfect Winding On Every Spool Their PLA filament is wound under controlled tension on precision machines. Every spool goes through a final inspection before shipping. The result is a spool that feeds smoothly from start to finish. Also, it looks great every time. Excellent for outdoor use ASA's one of the main advantages is excellent UV resistance. This, in combination with good high-temperature resistance, makes it perfectly suitable for making outdoor parts with a long lifespan. Here's a great example: Czech company Anitra System uses Prusament ASA for making GPS loggers attached to migratory birds, where long lifespan and high resistance are necessary. Perfectly smooth finish made with acetone vapors ASA is soluble in acetone. When exposed to acetone vapors, the model's surface melts and forms a glossy finish, hiding print layers and imperfections. The result resembles an injection-molded part. You can learn more about chemical smoothing in Prusa's blog article. Fine details without stringing Unlike other technical materials, ASA offers little to no stringing. This makes it suitable for printing tiny, detailed parts, such as tabletop figures and similar models. Basic Attributes Pros Great for outside use – UV stable Good high-temperature resistance Detailed prints without a stringing effect Can be smoothed with acetone vapors Can be easily sanded / post-processed Good mechanical resistance Cons Large models tend to warp. We recommend printing in an enclosure or printing large components with a less warping material, such as PETG. Produces a slight odor of burned plastic during printing (less than ABS) Contains styrene (potentially harmful fumes). We recommend printing in a well-ventilated area or using an enclosure with active filtration.
