• homogeneización y minimización: el grosor de la pared de los modelos de impresión 3D debe establecerse en un mínimo de acuerdo con las propiedades del material (> 1 mm según lo recomendado por ABS) para evitar la deformación o la fractura debido a la disminución.  JS Company admite paredes delgadas de hasta 0.3 mm de espesor, fuerza equilibrada y liviana.
• Transición de gradiente: los cambios repentinos en el grosor de la pared pueden conducir fácilmente a la concentración de tensión, por lo que las estructuras de gradiente deben usarse en el diseño. El equipo SLA de JS puede manejar estos detalles con precisión.

• Límite de ángulo de suspensión: se requiere soporte adicional cuando los ángulos de suspensión exceden los 45 grados.
• Estructuras internas complejas Puede reducir el consumo de material a través del soporte de panal, y los algoritmos JS pueden generar automáticamente soluciones de soporte eficientes.

El equipo FDM de grado industrial de JS puede lograr una alta precisión de ± 0.05 mm.

Compensación de dimensiones: los materiales termoplásticos tienen efectos de contracción y deben ajustarse de acuerdo con las propiedades de los materiales durante el diseño. 

• La plataforma de impresión de JS coloca automáticamente y procesa rutas complejas Para evitar que las cavidades complejas obstruyan el flujo de consumibles.

¿Cómo equilibrar la eficiencia y la precisión entre el grosor de la capa y la velocidad de impresión?

• High-precision model: SLA photocured layer thickness as low as 0.025mm and surface smoothness up to medical-grade standards Modo de prototipos rápidos: Impresión de alta velocidad con un grosor de 0.3 mm (velocidad 80 mm³/s) por control de temperatura ± 1 ° C utilizando la tecnología FDM, un aumento de eficiencia del 30%.
• Photosensitive resin: LED matrix partition exposure technology increases SLA curing speed by three times.
• Metal/Ceramic: SLS nylon printing supports 100% density adjustment, and the JS Company titanium alloy parts with forging-strength levels.

3.Post processing efficiency improvement plan

• Surface optimization: The FDM model can achieve polished SLA gloss, cost reduction of 50%.
• Functional enhancement: Electroplated nickel with conductivity reduced to 0.01Ω· cm printing of conductive silver ink printing.
• Fast delivery: Automated reprocessing lines reduce the delivery cycle of medical models to 48 hours (traditional 72 hours).

What is the importance of ink jet printing in 3D printing?

As an important branch of 3D printing, Ink jet printing has become a key technology in complex structure manufacturing, personalized customization and high performance parts production through precise control of micro-nozzles and multi-material compatibility. Its importance is reflected in the following:

1.High precision and meticulous performance

• Microscale printing: Ink jet technology uses micrometer level nozzles to precisely control material deposition, achieving complex geometry and fine details (such as microsensors).
• Surface smoothness: Layer upon layer of solidified liquid resin,such as UV curing resin. The surface quality is similar to that of traditional injection molding parts, suitable for high precision prototypes or consumer electronics components.

2.Integration of multiple materials and colors

• Hybrid material printing: Different materials (e.g. rigid, flexible, transparent resin) can be combined for a single printing to produce fully functional components (e.g. soft robots with sensors).
• Full-color 3D printing: Full-color models (such as medical anatomical anatomy models architectural visualizations) can be achieved by using an inkjet head directly to inkjet without the need for post-processing coloring.

3.Efficient production and rapid iteration

• High-speed printing: The nozzle works in parallel, shortens production time and is suitable for small volume customization (e.g. braces and hearing aids).
• Production on demand: Do not need mold, rapid digital manufacturing, to speed up the product development cycles.

4.Physical diversity and innovation

• Compatible with a wide range of materials: In addition to resins, conductive ink and bioinks can be printed, promoting applications in electronics and biomedical fields such as 3D printing circuits and artificial tissues.
• Sustainability: Some technologies use biodegradable materials, in line with environmental trends.

5.Technical constraints and improvement directions

• Material cost: The price of specialized photosensitive resin is relatively high and the development of low-cost materials needs to be promoted.
• Post-treatment requirements: some components need to be cleaned and re-solidified, process automation is the future focus.
• Size challenge: At present, it is better suited to small and medium-sized components, while large structures still require additional technology.

How to evaluate the professionalism of a 3D printing shop?

Technology Strength Assessment

1.Advanced equipment

• Check that the service provider is equipped with industrial-grade equipment (e.g. JS company's SLA light curing equipment, FDM industrial machine, SLS nylon printer with equipment accuracy ± 0.02mm and layer thickness as low as 0.025mm).
• Preference is given to service providers that support multi-technology integration,such as inkjet printing+laser sintering, to meet complex requirements.

2.Material adaptability

• Verify that its material base includes engineering plastics (ABS/PLA), metals (titanium alloys), ceramics, biomaterials, etc.
• Provide material performance test reports (such as tensile strength, hot deformation temperature, etc.) to ensure compliance with product requirements.

Service Capability Verification

1.Design support

• Technical evaluation and optimization suggestions wall thickness and support structure can be provided free of charge.
• Notice if it has reverse engineering capabilities (e.g. 3D scan repair, STL file repair).

2.Efficiency in delivery

• Depending on the urgency of the project, ask the service provider to specify a tiering strategy and printing speed.
• Data on the delivery cycle of historical orders are required (JS small batch orders are delivered within an average of 3 days).

3.Post processing support

• Check for value-added services such as polishing, dyeing and plating (e.g. JS shows surface roughness Ra<0.8 μm after polishing).
• Verify that it supports small batch customization.

Quality control system

1.Accuracy verification

• ISO 9001 certification reports and third-party testing reports are required.
• Sampling inspection of product size tolerance and surface quality.

2.Reliability testing

• Enquire whether ageing tests (e.g. high temperature and high humidity cycling) and mechanical performance tests tensile/compressive strength) have been conducted.
• Notice if it is industry certification (for example, whether aerospace components meet AMS 4999 standard).

Cost transparency

1.Quotation details

• Please separate printing, materials and post-processing costs to avoid hidden costs.
• Compare unit costs of similar service providers ( for example, JS's FDM printing cost is 20% lower than the market price).

2.economies of scale

Priority should be given to service providers with more than 100,000 hours of printing per year (JS has a large-scale production line that reduces marginal costs).

Cases and reputations

1.Industry case studies

• Check the official website or case library for success stories.
• Focus on cases similar to your own (healthcare, electronics, industry, etc.)

FAQs

1.How can 3D printing reduce material waste?

Traditional manufacturing often requires cutting and engraving, with a waste rate of 30% -50%. 3D printing is additive manufacturing, which involves printing only the parts needed, with a material utilization rate of over 90%. It is particularly suitable for small or complex production.

2.What is the best FDM printing layer thickness setting?

The prototype is rough, with layers of 200-300 microns (0.2-0.3 mm) thick, fast but rough on the surface. The model is excellent, with layers 50-100 microns (0.05-0.1 mm) thick, better detail and longer processing time.

3.Are SLS-printed powder materials reusable?

SLS-printed powder material can be reused, but after repeated use, its flowability decreases and their strength decreases slightly. The recovery rate of metal powder can be over 90%, and the number of uses needs to be controlled according to the material type to ensure performance.

4.Is 3D printing expensive? 

Small plastic printers for home use range from $280 to $1,400, and are suitable for DIY and small batch production. Mass production relies on industrial-grade metal/high-performance printers, requiring tens of thousands to millions.
