Gelatin-based high-strength 3D printing ink consists of o-nitrobenzyl alcohol-modified gelatin (GelNB), methacrylated hyaluronic acid sodium salt (HAMA), photoinitiator (NAP), light absorber, and phosphate aqueous solution. It is a ready-to-use, sterile 3D printing ink. This product is suitable for DLP and LCD printing, featuring fast crosslinking, high mechanical strength, excellent biocompatibility, and high printing resolution. In addition, it supports cell adhesion and biodegradation, offering broad application prospects for tissue repair and regenerative medicine.

Applications
1. Construction of complex biomimetic structures
2. Hydrogel bioreactor systems
3. Multi-scale microfluidic channels and organoid chips
Instructions for Use
1. Direct UseHeat the prefilled syringe at 37 ºC-60 ºC until the ink inside becomes a flowable liquid before use.
2. Use with Cell Suspension
① Incubate the product in a 37 ℃ incubator for 30–60 minutes to make the ink flowable.
② Prepare the cell suspension and transfer it into an empty luer-lock syringe.
③ Connect the two syringes using a luer-lock adapter. Pre-fill the adapter carefully before connection to avoid air bubbles. Gently push and pull until the ink is uniformly mixed with the cell suspension.
④ If the single-use volume is less than the product volume, transfer the required ink solution into an empty luer-lock syringe via a luer-lock adapter in advance.
⑤ It is recommended to mix the ink solution with the cell suspension in equal volumes.
3. Use with Drugs or Bioactive Factors
① Follow steps ①–④ in section 2.
② It is recommended to mix 10 parts of ink solution with 1 part of drug/factor solution to avoid excessively low concentration, which may affect the gel performance after curing.
4. Post-printing Processing
① After printing, rinse the printed construct with phosphate-buffered saline (PBS) or normal saline to remove residual resin. Post-cure the construct (recommended: 385 nm, ≥50 mW/cm², 30 s on each side) until fully cured.
② Immerse the fully cured construct in PBS or normal saline repeatedly 3 times, 30 min each time, to remove residual small molecules of photoinitiator and light absorber.Note: Adjust accordingly when used with drugs or factors.
Precautions
1. The product is sterilized. Maintain aseptic operation during use to avoid microbial contamination.
2. The outer surface of the product syringe can be wiped and disinfected with alcohol before use.
3. The product must be stored strictly away from light.
