В 3D -печати, why do manufacturers and designers turn to 3D printing ABS+PC instead of using pure ABS or pure PC? The answer lies in this blend’s ability to solve key pain points of single materials—like ABS’s poor heat resistance or PC’s high printing difficulty—by combining their strengths. This article breaks down what ABS+PC is, its unique properties, how to print it successfully, реальные приложения, and tips to avoid common issues, helping you choose and use this material with confidence.
What Is 3D Printing ABS+PC?
3D printing ABS+PC (acrylonitrile-butadiene-styrene + поликарбонат) is a hybrid engineering plastic that merges the advantages of two standalone materials. Think of it as a “super material”: it takes ABS’s toughness and low cost, pairs it with PC’s heat resistance and impact strength, and minimizes their weaknesses (like ABS’s low thermal deflection or PC’s high viscosity).
This blend isn’t just a simple mix—it’s a carefully engineered composite where the two polymers bond at the molecular level. Результат? A material that performs better than either ABS or PC alone for applications that need balance (НАПРИМЕР., durable parts that also handle heat).
ABS+PC vs. Pure ABS vs. Pure PC: Подробное сравнение
Choosing between ABS+PC, АБС, and PC can be tricky—each fits different needs. The table below contrasts their key properties to help you decide:
| Свойство | 3D Printing ABS+PC | Pure ABS | Pure PC |
| Стойкость | Высокий (flexural strength: 80–90 МПа)—resists drops and impacts better than pure ABS. | Хороший (flexural strength: 60–70 МПа)—durable but less strong than ABS+PC. | Очень высоко (flexural strength: 90–100 МПа)—but brittle at low temperatures. |
| Теплостойкость | Отличный (Температура теплового отклонения: 110–120 ° C.)—handles hot environments (НАПРИМЕР., car interiors). | Бедный (Температура теплового отклонения: 80–90 ° C.)—softens in heat. | Начальство (Температура теплового отклонения: 130–140 ° C.)—but harder to print. |
| Printing Ease | Moderate—lower viscosity than PC (avoids clogging) but needs heated bed (80–90 ° C.). | Easy—low melting point (210–230 ° C.), flows well during printing. | Difficult—high melting point (250–270 ° C.), high viscosity causes clogs. |
| Поверхностная отделка | Гладкий (needs light sanding)—better than ABS, not as smooth as PC. | Грубый (requires sanding/painting to smooth). | Очень гладко (minimal post-processing due to low shrinkage). |
| Расходы | Умеренный (\(30- )40 за кг)—more than ABS, less than PC. | Низкий (\(20- )30 за кг)—ideal for high-volume, Детали с низким нагреванием. | Высокий (\(40- )50 за кг)—only worth it for extreme heat/impact needs. |
Key Benefits of 3D Printing ABS+PC (And How They Solve Problems)
ABS+PC’s hybrid nature solves common headaches for 3D printing users. Вот 3 core benefits with real-world examples:
1. Сбалансированная сила & Теплостойкость
- Проблема: A designer needs a 3D-printed car cup holder that’s durable (resists being dropped) and handles hot coffee (до 80 ° C.). Pure ABS softens in heat; pure PC is too expensive.
- Решение: ABS+PC’s 110°C thermal deflection temperature and high toughness make it perfect— the cup holder doesn’t soften, and it survives accidental drops.
2. Easier Printing Than Pure PC
- Проблема: A small business wants to print industrial sensor housings that need heat resistance, but their 3D printer can’t handle PC’s high melting point (causes nozzle clogs).
- Решение: ABS+PC prints at 230–250°C (lower than PC’s 250–270°C) and has lower viscosity—no clogs, and the housings still handle the sensor’s 100°C operating temperature.
3. Cost-Effective Versatility
- Проблема: A toy manufacturer needs durable, heat-resistant toy parts (for outdoor use in summer) but can’t afford PC’s $50/kg cost for 10,000 единицы.
- Решение: ABS+PC’s $35/kg cost cuts material expenses by 30% против. ПК, and its 120°C heat resistance means the toys don’t warp in summer sun.
Step-by-Step Guide to Successful 3D Printing ABS+PC
Printing ABS+PC isn’t hard—follow this linear process to avoid mistakes like warping or clogging:
- Pre-Print Setup:
- Dry the ABS+PC filament (60–70°C for 4 часы). Like PC, ABS+PC absorbs moisture, который вызывает пузырьки в отпечатках.
- Set your 3D printer parameters:
- Температура сопла: 230–250 ° C. (start at 240°C for best flow).
- Температура нагретого слоя: 80–90 ° C. (prevents warping—critical for large parts).
- Скорость печати: 40–60 мм/с (slower than ABS to ensure layer adhesion).
- Test Print:
- Print a small test piece (НАПРИМЕР., 5 см куб) Чтобы проверить проблемы:
- If layers separate: Increase nozzle temperature by 5°C or slow print speed.
- If the part warps: Raise the heated bed temperature by 5°C.
- Full Print:
- Следите за первым 10 minutes—ensure the first layer sticks to the bed (use a thin layer of glue if needed).
- Avoid opening the printer door during printing (causes temperature drops and warping).
- Пост-обработка:
- Let the part cool to room temperature (1-2 часа) before removing it from the bed (предотвращает растрескивание).
- Sand rough edges with 300-grit sandpaper—light sanding is enough (unlike ABS, which needs heavy sanding).
Real-World Applications of 3D Printing ABS+PC
ABS+PC’s balance of properties makes it useful across industries. Вот 4 Ключевые варианты использования:
- Автомобиль: Prints interior parts like dashboard clips and cup holders. A car parts supplier uses ABS+PC to make 5,000 dashboard clips monthly—they resist heat from the car’s AC/heating system and don’t break when installed.
- Потребительская электроника: Makes phone cases and laptop stands. A tech startup’s ABS+PC phone case survives 1.5m drops (tested) and doesn’t warp when the phone overheats (до 45 ° C.).
- Промышленные инструменты: Creates hand-held tool handles (НАПРИМЕР., for screwdrivers). The handles are tough (сопротивляться износу) and handle the tool’s friction heat (до 90 ° C.) better than ABS.
- Игрушки & Хобби: Produces outdoor toy parts (НАПРИМЕР., Римские рамки). A toy company’s ABS+PC drone frame survives crashes and doesn’t warp in summer sun (против. ABS frames that soften).

Часто задаваемые вопросы
- Q.: Can I use ABS+PC with a regular 3D printer (not industrial-grade)?
А: Да! Most desktop 3D printers with a heated bed (80–90 ° C.) and nozzle that reaches 250°C can print ABS+PC. Just ensure the printer has good temperature control (avoids overheating).
- Q.: Do I need a special nozzle for 3D printing ABS+PC?
А: A standard brass nozzle works for small prints, but for high-volume printing (100+ части), use a stainless steel nozzle (more durable—ABS+PC’s toughness can wear brass nozzles over time).
- Q.: How does ABS+PC hold up to outdoor weather (дождь, солнце)?
А: It’s weather-resistant—ABS+PC resists rain (doesn’t absorb water like wood-based filaments) and sun (UV rays cause minimal fading over 6 месяцы). Для долгосрочного использования на открытом воздухе (1+ год), apply a UV-resistant coating.
