• Propiedades clave: Opaco (usually milky white), no tóxico, excellent impact strength, buena estabilidad dimensional, resistencia química.
• Limitaciones: Requires a heated build plate to prevent warping.
• Ideal para: Prototipos funcionales, productos de consumo (P.EJ., fundas telefónicas, piezas de juguete), componentes interiores automotrices.

2.3 ordenador personal (Policarbonato)

• Que es: A high-performance thermoplastic known as an “engineering plastic.”
• Propiedades clave: Alta fuerza, resistencia al calor (hasta 130 ° C), resistencia al impacto, bending resistance.
• Unique Benefit: Parts can be directly assembled and used (No se necesita postprocesamiento para muchas aplicaciones).
• Ideal para: Componentes aeroespaciales, equipo médico (P.EJ., Presentaciones de herramientas de diagnóstico), piezas exteriores automotrices.

2.4 Nylon (Poliamida)

• Que es: A lightweight thermoplastic with excellent wear resistance.
• Propiedades clave: Resistencia al calor, low friction coefficient, alta resistencia a la tracción (even without post-processing).
• Limitaciones: Opciones de color limitadas (can be colored via spray painting or dip dyeing).
• Ideal para: SLSS (Sinterización láser selectiva) huellas dactilares, partes móviles (P.EJ., engranaje, aspectos), equipo deportivo (P.EJ., pedales de bicicleta).

2.5 Resina fotosensible

• Que es: A liquid material made of polymer monomers and prepolymers, cured by UV light.
• Propiedades clave: Fast curing speed, acabado superficial liso, transparent to translucent matte appearance.
• Unique Benefit: Delivers ultra-high precision (down to 0.1mm layer heights).
• Ideal para: Joyas (P.EJ., custom pendants), modelos dentales (P.EJ., crown prototypes), small high-detail parts (P.EJ., miniaturas).

2.6 Materiales especializados

For advanced projects, estos 3D Plastics impresos offer unique solutions:

• Plásticos de alto rendimiento: Pei (polyetherimide), OJEADA (cetona de éter poliéter), Pes (polyether sulfone), and PPSU (polyphenyl sulfone) — used for extreme environments (P.EJ., piezas de motor aeroespacial, implantes médicos).
• Water-soluble plastics: PVA (alcohol polivinílico) — used as support structures for complex prints (dissolves in water, no manual removal needed).

3. How to Choose the Right 3D Printed Plastic: 4 Factores clave

Con tantas opciones, how do you pick the best 3D printed plastic? Follow this step-by-step process:

1. Define Your Project’s Needs:

• Es la parte funcional (P.EJ., un engranaje) o decorativo (P.EJ., una figura)?
• Will it be exposed to heat (P.EJ., near an engine) or water (P.EJ., a outdoor planter)?
• Does it need to be biodegradable (P.EJ., a temporary medical splint)?

2. Consider Your Budget:

• Low-cost options: Estampado (\(20- )30 por kg), Abdominales (\(25- )35 por kg).
• Opciones de rango medio: ordenador personal (\(40- )60 por kg), Nylon (\(50- )70 por kg).
• High-cost options: Photosensitive resin (\(80- )150 por litro), OJEADA (\(300- )500 por kg).

3. Check Compatibility with Your Printer:

• PLA/ABS work with most FDM (Modelado de deposición fusionada) impresoras.
• Nylon requires SLS printers.
• Photosensitive resin needs a resin 3D printer (Curado UV).

4. Evaluate Post-Processing Needs:

• Do you have time for sanding (Abdominales) or dyeing (Nylon)?
• Can you afford water-soluble supports (PVA)?

4. Yigu Technology’s Perspective on 3D Printed Plastic

En la tecnología yigu, creemos 3D printed plastic is the backbone of accessible innovation. Our engineering team prioritizes materials that balance performance and usability—for example, we often recommend PLA for beginners (fácil de imprimir, bajo costo) and PC/PEEK for industrial clients (alta durabilidad, resistencia al calor). A medida que evoluciona la impresión 3D, we’re seeing a shift toward eco-friendly options (like plant-based PLA) and ultra-high-performance plastics (like PEEK for medical implants). We advise clients to align material choice with long-term goals: a prototype may only need PLA, but a critical aerospace part demands PEEK.

5. FAQ About 3D Printed Plastic

Q1: Is 3D printed plastic toxic?

El más común 3D Plastics impresos (Estampado, Abdominales, ordenador personal) are non-toxic when used correctly. PLA emits a slight sweet odor when heated (seguro), while ABS may release fumes—we recommend a well-ventilated space or a HEPA filter for ABS printing. Photosensitive resin is safe once cured but requires gloves when handling liquid resin.

Q2: Can 3D printed plastic parts be reused?

Termoplástico (Estampado, Abdominales, ordenador personal) can be melted and reshaped multiple times, making them reusable. Termossets (resina epoxídica) and cured photosensitive resin cannot be reused, as their chemical structure changes permanently during curing.

Q3: What’s the most durable 3D printed plastic?

Para uso general, PC and Nylon offer excellent durability. Para condiciones extremas (calor alto, presión), PEEK is the top choice—it’s used in medical implants and aerospace parts because of its strength and biocompatibility.
