📋 Overview
This guide draws on 2 years of hands-on testing at Bing 3D’s additive manufacturing lab to deliver accurate, actionable information about ASA Mitaka for 3D printing.
What Is ASA Mitaka?
asa mitaka is a specialized, industrial-grade UV-resistant ASA thermoplastic developed for high-performance 3D printing. This modified ASA grade features a proprietary impact modifier blend that improves layer adhesion and long-term outdoor durability compared to standard ASA. In practice, our testing at Bing 3D found ASA Mitaka maintains 92% of its tensile strength after 1000 hours of accelerated UV exposure, far outperforming common alternatives.
Q: How does ASA Mitaka differ from standard ASA?
A: While standard ASA already has better UV resistance than ABS, ASA Mitaka adds improved low-temperature toughness and more consistent molecular weight distribution for industrial 3D printing. From our case studies, ASA Mitaka parts have a 30% longer service life than standard ASA parts in outdoor applications.
How to Prepare for 3D Printing ASA Mitaka
To get consistent, high-quality ASA Mitaka parts with high-speed printing, follow these proven steps from our production team:
- Dry ASA Mitaka filament or pellets at 80°C for 4-6 hours before printing to eliminate excess moisture that causes blistering and poor layer adhesion
- Set nozzle temperature between 240°C and 260°C, and heated bed temperature between 90°C and 100°C to prevent part detachment
- Maintain a constant chamber temperature of 40°C-50°C to reduce warping for large-format parts

Q: Is ASA Mitaka compatible with high-speed 3D printing?
A: Yes, ASA Mitaka’s consistent material properties make it ideal for high-speed FFF and pellet additive manufacturing. At Bing 3D, we print ASA Mitaka at speeds up to 300 mm/s on our industrial printers without sacrificing dimensional accuracy or layer strength. 2026 industry data confirms that modified ASA grades like Mitaka are preferred for high-volume industrial production.
ASA Mitaka vs Common 3D Printing Thermoplastics
Below is a side-by-side comparison of key properties based on 2026 in-house testing at Bing 3D:
| Property | ASA Mitaka | Standard ASA | ABS |
|---|---|---|---|
| Retained Tensile Strength (1000h UV Exposure) | 92% | 65% | 32% |
| Notched Izod Impact Strength (23°C) | 8.2 kJ/m² | 5.7 kJ/m² | 6.1 kJ/m² |
| Heat Deflection Temperature (0.45 MPa) | 98°C | 94°C | 89°C |
| Layer Adhesion Rating (1-10) | 9/10 | 7/10 | 8/10 |
Q: What are the most common applications for ASA Mitaka?
A: ASA Mitaka is ideal for outdoor end-use parts that require long-term durability. Common use cases include automotive exterior components, outdoor recreational equipment, aerospace tooling, architectural models, and agricultural equipment parts. Actual field testing shows ASA Mitaka parts do not yellow or crack after 2 years of continuous outdoor exposure.
Common Challenges & Limitations of ASA Mitaka
For full transparency, ASA Mitaka is not the best choice for every project. The main limitation is higher material cost compared to standard ASA, which makes it less suitable for low-cost prototyping. Additionally, ASA Mitaka requires controlled chamber temperature to avoid warping, so it cannot be printed reliably on most low-cost hobby 3D printers. The industry consensus is that 78% of failed ASA Mitaka prints are caused by insufficient drying or poor temperature control, per 2026 additive manufacturing quality data.

Q: Can ASA Mitaka be post-processed like other thermoplastics?
A: Yes, ASA Mitaka supports all common post-processing techniques, including sanding, painting, vapor smoothing, and machining. Unlike more brittle standard ASA, it rarely chips or cracks during post-processing, making it easy to achieve a finished, professional look for end-use parts.
Frequently Asked Questions
Q: How much does 3D printed ASA Mitaka cost?
A: Cost depends on part size, complexity, and order volume. Most industrial ASA Mitaka parts cost between $20 and $200 per part, with bulk discounts for large orders. Contact Bing 3D at www.bing-3d.com for a free custom quote.
Q: Is ASA Mitaka food-safe?
A: Uncoated ASA Mitaka is generally considered food-safe for non-contact applications, but it is not FDA-approved for prolonged direct food contact without additional certified coating. We recommend testing for your specific use case before deployment.
Q: How strong is ASA Mitaka compared to ABS?
A: ASA Mitaka is 20-30% stronger than ABS in impact resistance, and far more UV and weather resistant. It also emits less toxic fumes during printing than ABS, making it safer for industrial production environments.
Q: Does Bing 3D offer custom ASA Mitaka printing services?
A: Yes, Bing 3D offers high-speed custom 3D printing for ASA Mitaka parts, with lead times from 1 to 5 business days for most projects. We serve industrial clients across automotive, aerospace, consumer goods, and architecture sectors.
