GelMA 3D Printing Ink is composed of methacrylated gelatin (GelMA), photoinitiator (NAP), light absorber, and phosphate aqueous solution. It is a ready-to-use 3D printing ink subjected to sterile processing. The GelMA-based bioink exhibits excellent cytocompatibility and rapid crosslinking properties, making it suitable for DLP and LCD printing. Furthermore, this product features cell adhesiveness and biodegradability, offering broad application prospects in tissue repair and regenerative medicine.

Application
1. Biomimetic structure construction
2. Organoids
Instructions for Use
1. Direct UseHeat the pre-filled syringe barrel at 37 ºC-60 ºC until the ink inside becomes a flowable liquid before use.
2. Use with Cell Suspension
① Place the product in a 37 °C incubator for 30–60 minutes to allow the ink in the barrel to become a flowable liquid.
② Prepare the cell suspension and transfer it into an empty luer-lock syringe.
③ Connect the two syringes using a luer-lock adapter. Carefully pre-fill the luer-lock adapter before connection to avoid introducing air bubbles. Gently push back and forth until the ink is completely and uniformly mixed with the cell suspension.
④ If the single-use volume is less than the product loading volume, the required amount of ink solution can be transferred into an empty luer-lock syringe via a luer-lock adapter in advance.
⑤ It is recommended to mix 10 parts of ink solution with 1 part of cell suspension to prevent the gel properties from being affected by excessively low product concentration.
3. Use with Drugs or Factors
① Follow the procedures ①–④ described in section 2.
② It is recommended to mix 10 parts of ink solution with 1 part of drug or factor solution to prevent the gel properties from being affected by excessively low product concentration.
4. Post-printing Processing
① After printing, rinse the printed model with phosphate buffered saline (PBS) or normal saline to remove residual resin solution, and post-cure the model (recommended: 385 nm, ≥50 mW/cm², 30 s on each side) until the model is fully cured.
② Immerse the fully cured printed model in PBS or normal saline repeatedly 3 times, 30 min each time, to remove residual small molecules of photoinitiator and light absorber.
Note: When used in combination with drugs or factors, handle appropriately.
Precautions
1. This product is sterilized. Maintain aseptic operation during use to avoid microbial contamination.
2. Before use, the outer wall of the product syringe can be wiped and disinfected with alcohol.
3. The product must be stored strictly protected from light.
