AON3D Readyprint™ ABS
AON3D Readyprint™ ABS (acrylonitrile butadiene styrene) is an amorphous thermoplastic polymer commonly used in additive manufacturing. ABS is commonly used for its impact resistance, low density, and affordability. ABS excels in form, fit, and function prototyping such as jigs and fixtures due to its strength, low cost, and ease of printability. ABS is best for medium-large parts without too many fine details.

Moisture Control
Readyprint™ ABS is factory pre-dried and should be installed in the filament dry storage and feed system prior to printing to prevent moisture uptake and minimize the impact of moisture on the printing process. In ambient air, ABS is mildly susceptible to hydration. It will generally remain printable, but surface finish and seam quality will suffer after prolonged exposure.
If the filament is hydrated, dry filament at 70ºC for 4-6 hours in a convection oven. Ensure drying equipment respects our site requirements to ensure adequate drying performance is achieved. Store filament in air-tight bags or containers alongside silica or zeolite desiccant. Be sure to replace desiccant regularly as its moisture capture ability is exhausted.
For more information, see the Filament Drying and Moisture Control page.
Build Platform Adhesion
For instructions on how to inspect the AON3D build plates, refer to the Clean Build Platform and Build Chamber procedure for AON M2+ or the Inspect and Clean Build Plates procedure for AON-M2 and AON-M2 2020.
PEI Build Sheet
ABS prints best on the PEI build sheet as it exhibits great adhesion behavior at moderate cost and improved durability over PC sheets. The PEI film is sensitive to Z offset calibration and thermal stability of the printer system. For best results, ensure that the machine has reached thermal equilibrium before calibrating. If the bed-to-nozzle distance is too small, or the first layer is too hot, the part may be difficult to remove without damaging the part and/or build sheet.
Garolite G-10 Build Sheet
ABS prints well on the Garolite G-10 build sheet due to strong adhesion behavior while at recommended bed temperatures and clean removal once the build sheet is cooled down. The G-10 surface is sensitive to Z offset calibration and scratches or scuffs on the surface. For the best results, use a lower first layer speed, a higher the first layer extrusion temperature, and remove the parts gently after prints are complete to minimize damage on the build surface.
CF-PEEK Composite Plate
ABS prints well on CF-PEEK Composite Plate build sheet as it exhibits great adhesion behavior while hot and clean removal after cooling down. The CF-PEEK composite plate is sensitive to Z offset calibration and thermal stability of the printer system. For best results, reduce the First Layer Speed, increase the first layer extrusion temperature, or increase bed temperature.
Caution: First layer extrusion temperatures in excess of 280ºC or elevated bed temperature selections can cause parts to permanently weld to the print surface.
General Process Settings
For best results, process settings should be adjusted based on a particular model geometry. If you require process development support, our Applications Engineering team can help! Send us a message at help@aon3d.com to consult with one of our Additive Manufacturing Specialists.

Post-Processing
Allow all machine components to reach room temperature before proceeding further. Failure to allow components to cool down will result in thermal injury (burns) to personnel.
Parts removed before reaching room temperature have a chance of globally warping.
Troubleshooting & Best Practice
High-Speed Printing
ABS is well suited for high productivity applications. With appropriate nozzle size and layer height selection, ABS can be printed at tools speeds of up to 100 mm/s.
Key best practices to consider when selecting higher print speeds:
- Print speed above 100 mm/s induces significant stress in the deposited material, leading to an increased risk of warping and shrinkage under high-temperature service.
- Sharp corners, small holes, and other surface details begin to lose dimensional accuracy and resolution beyond 60-80 mm/s.
- Increased layer height is an effective alternative to high tool speeds to minimize print times while reducing overheating, residual stress, and underextrusion issues.
- Increased extrusion width or larger nozzle size selection are also effective means to reduce print time.
- At high deposition rates (elevated tool speed, layer height, or nozzle size), an increased extrusion temperature is also required to ensure consistent flow and adhesion of extruded material.
Overheating
ABS is prone to overheating due to its low thermal conductivity and elevated ambient temperature of the printing chamber. Overheating typically presents as deformed part features, curling edges, loss of dimensional accuracy, and increasingly glossy part surface finish.
Risk of overheating increases as:
- part sizes fall below 30 mm x 30 mm cross-sectional areas.
- print speeds increase beyond 60-80 mm/s.
- chamber temperature is greater than 60ºC.
- chamber convection is turned off.
Nozzle size and part geometry will impact these rules of thumb.
Moderate reduction of chamber temperatures down to 50ºC can also have a positive impacts on overheating. However, for large components (greater than 50 mm x 50 mm x 50 mm), warping effects may demand an elevated chamber temperature (>50ºC) selection.
For medium size cross sections (down to 10 mm x 10 mm), reduction of print speed (down to 40 mm/s) and extrusion temperature (down to 220ºC) can have a mitigating effects on overheating. For cross sections below 10 mm x 10 mm, tool contact with the print surface will dominate heating behavior. Introducing layer to layer dwell commands, or adding duplicate parts in the build, is the best way to manage heat accumulation in this case.
Polymer Degradation
ABS is sensitive to UV light, causing mechanical property deterioration if sufficiently exposed. UV degradation of ABS is difficult to observe on raw filament but, can often be seen once the material has been processed at extrusion temperatures. Avoid exposing the filament to the sun or other UV sources by storing it in a sealed package or container.
