  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

  Classification of reasons	Concrete manifestations	Influencing results
  Improper layer thickness	Excessive layer thickness (>0.2mm).	Surface roughness excess (Ra >6.3μm).
  Temperature parameter errors	Low Printing temperature (if PLA is below 190°C).	The material cannot be bonded and the bond between layers is insufficient.
  Lack of support structures	Suspension structure without added support.	Lower cave-in, inner void.
  Scanning too fast	SLA laser scan speed>8m/s.	Decreased molding accuracy (±0.1mm 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).
