Photopolymerization
The resin contains photosensitive monomers and photoinitiators. When exposed to ultraviolet light of a specific wavelength (such as 365nm or 405nm), the photoinitiator activates, triggering cross-linking and polymerization of the monomers, instantly converting the liquid resin into a solid state.
Layer-by-layer stacking
The print platform first descends to the resin tank, allowing the resin to fill to a single layer thickness (25-100μm). After the light source cures a single layer according to the model's 2D cross-section data, the platform rises and refills with resin, repeatedly stacking the parts to form a 3D object.
Precise light source control
Light sources such as lasers (SLA) or LED arrays (DLP) illuminate only the areas requiring curing based on the model's layering data, ensuring that each layer's cross-section precisely matches the design and avoiding excess resin curing.
Post-curing
Printed models contain uncured components and require a second UV exposure to further polymerize the resin, improving the model's hardness, strength, and dimensional stability to meet performance requirements.
How to test the printing quality of resin?
●Basic parameter verification: Print a standard test model using industry-standard test models (such as the Calibration Cube or Resin Test Pyramid). After printing with default parameters, measure dimensional accuracy (measure length, width, and height with a caliper, with an error of < 0.1mm) and layer texture (observe the side surface under strong light to ensure uniformity) to rule out parameter adaptation issues.
●Detail expression test: Print models with fine structures (such as 0.1mm columns and tiny text). Observe whether the details are intact (no broken columns, clear text) and the surface is smooth (no noticeable graininess). This will determine the resin's resolution and curing quality.
●Mechanical property verification: Test the resin type for drop and compression resistance (no cracking after a light drop or deformation after pressure) for rigid resins; and for resilience (no permanent deformation after bending) for flexible resins to ensure compliance with usage requirements.
●Stability test: After printing, let the model sit for 24 hours to observe for cracking or deformation. Soak the model in a liquid (such as water or alcohol) for 2 hours to check for swelling or discoloration to verify long-term stability.
FAQ
1.How do I choose a resin that's compatible with my printer?
Confirm the printer's UV light source wavelength (365nm/405nm, etc.) and match it to the wavelength marked on the resin. For SLA, choose a universal resin; for DLP, prioritize low-shrinkage resins. Consider the resin's viscosity (avoid resins with a viscosity > 5000cP, which can cause uneven coating).
2.How do I choose between 100ml/500ml/1L packaging?
Choose 100-500ml for trials/small items (to prevent spoilage), and 1L+ for bulk (cost-effective). Check the production date to ensure the remaining shelf life is ≥ 6 months.
3.What certifications are required for biocompatible resins? Can standard resins be used in medical applications?
ISO 10993 (biosafety) is required, and ISO 13485 is added for dental applications. Standard resins are uncertified, contain irritants, and are strictly prohibited for medical use.
4.What is the shelf life of a resin? Can it still be used after the expiration date?
12-24 months for unopened resin (depending on the packaging). Use within 1-3 months after opening. Expired resin tends to increase in viscosity and cure unevenly, so it is not recommended.
5.How do you determine the strength and flexibility of resin when purchasing?
For rigidity, look at the tensile strength; for flexibility, look at the Shore A hardness (the lower the Shore A, the softer). Prioritize brands that provide test reports.
6.How do you choose between imported and domestic resins?
If you have a sufficient budget and require special properties (such as high-temperature resistance), choose imported resins. For general applications, domestic resins offer better value for money. It's important to verify whether they have quality inspection reports.
