Atomic Filament ASA Standard White Summary

This filament is tricky to print, heat-resistant and weatherproof. Worth watching: it can be a little moisture-sensitive and a bit smelly to print.

Skill level Advanced

Advanced. Wants careful tuning, strong bed adhesion, and usually an enclosure.

Print characteristics

Layer adhesion ExcellentBed adhesion ChallengingBridging & overhang GoodSpeed sensitivity ModerateWarping ModerateShrinkage 0.4-0.7 %Stringing LowOozing LowOdor Moderate

Strengths

Solid strength for everyday parts
Handles heat well
Holds up to sunlight without fading or going brittle
Weather-resistant for long-term outdoor use
Layers bond strongly for clean, watertight prints
Prints clean with minimal stringing
Good electrical insulator
Food-safe potential with the right setup

Things to watch

Can warp on large or sharp-cornered prints
Picks up moisture over time, store it with desiccant
Gives off noticeable fumes, print with ventilation or filtration
Fussy about bed adhesion, use a brim, glue, or a textured plate

Specialties

UV ResistantResists degradation from sunlight exposure (UV radiation) and outdoor weather conditions. For outdoor signage, garden equipment, automotive exterior parts, or marine components.

Heat ResistantWithstands elevated temperatures (hot car, warm electronics) without deforming. Printable on standard printers. HDT ~80-120°C.

Tough / Impact ResistantEngineered to resist breaking, cracking, or shattering under impact. Unlike standard PLA, which snaps, this flexes slightly before breaking. Ideal for parts that get dropped, bumped, or stressed.

Chemical ResistantResists damage from oils, fuels, acids, industrial chemicals or solvents. For laboratory equipment, fuel system components, or chemical storage.

Vapor SmoothableReacts to chemical vapors (acetone for ABS/ASA, or other solvents) that partially melt the surface. Creates a glossy, injection-molded finish with no layer lines.

SandableEasily sanded, filed, or carved without gumming up sandpaper.
