Prof. Lab ASA White 1 kg – professional ASA filament for outdoor use

Professional ASA filament Prof. Lab ASA White 1 kg is designed for users who need highly durable functional parts with a long service life even in demanding conditions. ASA (Acrylonitrile Styrene Acrylate) material is developed as a replacement for ABS with significantly better UV stability and weather resistance, so it does not degrade or yellow during long-term exposure to sunlight.

Thanks to the combination of mechanical strength, toughness, and thermal resistance, it is ideal for technical prints, prototypes, covers, brackets, and outdoor parts – anywhere where PLA or PETG is insufficient.

Main advantages and use

• High resistance to UV radiation and weather conditions Ideal for outdoor parts – electronics covers, sensor mounts, garden accessories, advertising and information boards, etc.
• Strength and toughness comparable to ABS Excellent endurance to mechanical stress, impacts, and vibrations, suitable for structural parts, brackets, mounting elements, or prototypes in industry and workshops.
• Better dimensional stability than ABS ASA generally exhibits lower deformation and warping during printing than classic ABS (with correct bed temperature and an enclosed print chamber), facilitating the printing of larger parts.
• Resistance to water and chemicals Parts made of ASA resist moisture and common chemical substances well, which is useful for technical components, covers, and fixtures in more demanding environments.
• Matte white surface The white color provides a clean technical appearance, is well-suited for design and functional parts, and allows for easy post-processing (sanding, gluing, filling, painting).

Recommended use

• outdoor and exterior parts (covers, mounts, camera and sensor brackets)
• automotive accessories and brackets for interior and exterior
• technical prototypes and functional components
• electrical and electronic boxes and covers
• parts for the workshop, garage, or industrial environment

Technical specifications

The specific brand "Prof. Lab" is based on the typical behavior of high-quality ASA filaments on the market. Values are indicative, suitable for 3D printing settings.

Basic parameters

• Material: ASA (Acrylonitrile Styrene Acrylate)
• Color: White
• Filament diameter: 1,75 mm
• Net weight: 1 kg
• Recommended material density: approx. 1,05 g/cm³

Recommended print settings

• Nozzle temperature: 240–260 °C (start around 245–250 °C and adjust according to the printer and speed)
• Bed temperature: 90–110 °C (to reduce warping, the upper part of this range is recommended)
• Recommended print speed: 30–80 mm/s (for quality surface and dimensional accuracy, use medium values)
• Print chamber: recommended enclosed or at least partially covered printing area
• Part cooling: minimal to none (only light blowing for small details)

Material properties (typical ASA)

• UV resistance: high, suitable for long-term outdoor use
• Thermal resistance: up to approx. 90–100 °C (HDT at 0,45 MPa)
• Water resistance: good
• Chemical resistance: good against common oils and some solvents
• Strength and toughness: comparable to or higher than ABS

Tips for successful ASA printing

• Use glue, adhesive spray, or a special bed for ABS/ASA type materials to minimize corner lifting.
• Prevent drafts – ASA is sensitive to rapid temperature changes, so using an enclosed printer or cover is ideal.
• For larger parts, consider a brim/raft to improve bed adhesion.
• For a perfect look, prints can be sanded, filled, and painted – ASA processes well.

Who is Prof. Lab ASA White suitable for

• Advanced hobby users looking for a reliable material for functional parts
• Professional users and companies printing technical components, prototypes, and outdoor parts
• Makerspaces, schools, and laboratories where a more durable alternative to PLA/PETG is needed for practical projects
