4.Level of control of reprocessing technologies

After the prototype model is completed, it needs to be polished and electroplated. JS company ensures that these processes do not introduce additional errors through rigorous quality control systems such as three dimensional inspections and surface roughness testing.

Why choose PEEK material for medical equipment?

1.Biocompatibility and safety

PEEK is ISO 10993 cytotoxicity testing and FDA certified, and its prototyped model can be used directly for human implant validation to avoid the risk of immune rejection.

2.Matching mechanical properties to human needs

In orthopedic prototyping, PEEK (3.6 GPa) has an elastic modulus close to human bone (1-20 GPa) that reduces stress shielding and prolongs the life of the implant.

3.High temperature and chemical resistance

Prototyped of surgical instruments require repeated high-temperature sterilization (such as autoclaving at 134 °C), where PEEK maintains a stable size and is resistant to corrosion by disinfectants such as alcohol and hydrogen peroxide.

4.Capacity to implement complex structures

Using 3D printing, PEEK can be used to manufacture prototyped structures such as porous bone scaffolds, promote bone cell growth and reduce material usage to achieve lightness.

5.Balancing cost and efficiency

Compared to titanium alloys, PEEK reduces processing costs by 30%-50%, shortens shortens prototyping cycles by 40%, and makes suitable for the development of small-scale custom medical devices.

What are the special requirements for prototype materials in the military industry?

1.Extreme environmental adaptation

2.Excellent mechanical performance

High intensity/lightweight: The structure of the missile body requires the use of carbon-fibre-reinforced composites (five times the specific strength of steel), such as the J-20 fuselage components.

Shock and fatigue resistance: The cartridge is made of tungsten alloy (density (density 19.3g/cm³) to withstand the blast, and aircraft landing was made of ultra-high strength steel (tensile strength ≥1500 MPa).

Creep-resistance and abrasion resistance: Tank tracks were coated with high manganese steel (working hardness index ≥0.3) and missile rails were coated with tungsten carbide (friction coefficient ≤0.1).

3.Security, confidentiality and counter-surveillance

Electromagnetic shielding: The stealth fighter jets coating inhibits radar radar detection ferrite absorbing materials (reflection loss ≥20 dB).

About Key Technologies and Applications

1.PLA Rapid prototyping:

• Printing parameters: Layer thickness 0.1mm, filling density -40% to avoid warping due to shrinkage.
• Post-treatment: In order to eliminate internal stress and improve the dimensional stability of the prototyped model, it was subjected to heat treatment (baking at 60 °C for 2 hours).

2.Adapting public PHA to medical conditions:

• Sterilization compatibility: Supports ethylene oxide sterilization (residue ≤10ppm) to meet the prototyping requirements for surgical instruments.
• Degradation control: A controlled degradation cycle of 6 months to 2 years can be achieved by regulating molecular weight (50,000-200,000 DA).

3.Limitations of natural fiber reinforcement

Hygroscopicity: Bamboo fiber can absorb up to 15% of water in high humidity environments and require surface modification to accommodate precision rapid prototyping components.

4.Compost degradation conditions

Industrial composting standards: Degradation is required at temperatures of 58 degrees Celsius and humidity over 80%. household composting is only 30-50% more efficient than industrial conditions.

What are the common reasons for rapid prototyping failures?

Reasons related to substance

1.Excessive shrinkage: After cooling, the volume of the material shrinks by more than 0.5mm, resulting in prototype deformation and hole displacement, especially affecting the precision of precision components.

2.Excessive moisture absorption: Materials such as PLA and nylon easily absorb moisture from the air, resulting in a 30% reduction in strength, resulting in flaking or surface cracks between layers and undermining the structural integrity of rapid prototyping parts.

3.Poor material compatibility: When the photosensitive resin does not match the printing equipment, problems such as clogging and wire breakage are likely to occur, leading to interruption of printing or deterioration of surface quality.

4.Differences in thermal expansion coefficient: High thermal expansion coefficient of metallic materials in the course of high temperature processing, will occur deformation, leading to precision components blockage or size tolerance, increasing the cost of later correction.

5.Material performance mismatch: If the selected prototype material is not strong enough or high brittleness, it may fracture during the test and design function cannot be verified.

Process parameter setting error

JS has taken relevant measures in this regard:

• Material verification: Material shrinkage rate test before printing (recommended shrinkage <0.5%).
• Parameter optimization: Optimal layer thickness (recommended 0.05-0.15 mm) and temperature window determined by test printing.
• Model Inspection: Non-manifold geometry and thin wall structures were detected using CAD software (recommended minimum wall thickness ≥0.8mm).
• Environmental control: Stable workshop temperature and humidity (25±2°C /40-60% RH).
• Post-treatment specification: Develop standardized scaffold removal and cleaning processes (e.g. ultrasonic cleaning time ≤5 minutes).

How does JS company ensure the stability of prototype size?

3.Digital quality control: Through CAD document pre-review and 3D inspection equipment, to monitor the product size accuracy throughout the process, and timely correct possible deviations.

4.Environmental and process standardization: Maintain stable workshop humidity, implement uniform process parameters, and reduce the influence of environmental factors on material stability.

5.Experience-driven process optimization: A team of engineers with 20 years of experience, more than 30 technical training sessions per year, continuous improvement of process solutions, and increased consistency in repeat production.

Résumé

In the field of rapid prototyping, the boundary of material selection is constantly being reshaped, which drives the evolution of prototyping model from simple form verification to functional and intelligent. From its early reliance on a single engineering plastic to now covering metals, ceramics, biobased materials materials and smart composites, 3D printing has given prototypes properties closer to the end product through material innovation.

With continuous breakthroughs in materials science, future prototype models will overcome traditional performance limitations, achieve more complex structural validation and functional testing in aerospace, consumer electronics, and bioengineering, and further cement the status of rapid prototyping technology as a core tool for product development.
