应用领域
1、高强度、高弹性植入器件(如假体、气管等)
2、高精密、复杂水凝胶器件(如支架、血管等)
3、微针制备
使用建议
1、本产品可与药物或因子等混合使用
① 配制药物或因子溶液,过膜除菌 (0.22 μm),并将其移入空的鲁尔接口注射器内。
② 将上述注射器与本产品通过鲁尔锁适配器连接,连接前小心地将鲁尔锁适配器预先填充,以免引入气泡。轻轻地来回推动,至墨水与药物或因子溶液完全混合均匀。
③ 如果单次使用量低于产品装样量,可预先将所需量墨水溶液通过鲁尔锁适配器转移至空的鲁尔接口注射器内。
④ 建议将十份墨水溶液与一份药物或因子等溶液混合,以免产品浓度过低影响固化后凝胶性能。
2、打印参数如下表所示

3、打印后使用磷酸盐缓冲液或生理盐水对打印模型进行冲洗,将残余胶液冲洗干净,并对打印模型进行后固化 (推荐:385 nm,≥50 mW/cm²,各方向30 s),至模型完全固化。
4、取完全固化后的打印模型置于磷酸盐缓冲液或生理盐水中反复浸泡3次,每次30 min,除去残留的光引发剂及光吸收剂小分子。注:与药物或因子等混合使用时,酌情处理。
注意事项
1、产品经无菌处理,取用时注意无菌操作,避免微生物污染。
2、使用前,产品注射器外壁可用酒精擦拭消毒。
3、产品需严格避光保存。
打印效果展示

The PVA-based high-strength 3D printing ink is composed of o-nitrobenzyl alcohol-modified polyvinyl alcohol (PVANB), methacrylated sodium hyaluronate (HAMA), photoinitiator (NAP), light absorber, and phosphate aqueous solution. It is a ready-to-use 3D printing ink subjected to sterile processing. This product is suitable for DLP and LCD printing and features rapid crosslinking, ensuring high efficiency during the printing process. Meanwhile, the product exhibits high mechanical strength and can maintain structural stability during printing, enabling high-precision, high-fidelity fabrication of non-planar and complex structures. Furthermore, owing to the multiple reactive chemical sites of PVA, the printed structures can be chemically crosslinked to modify material properties, further expanding its application scenarios.

Application
1. High-strength, high-elasticity implantable devices (e.g., prostheses, trachea, etc.)
2. High-precision, complex hydrogel devices (e.g., scaffolds, blood vessels, etc.)
3. Microneedle fabrication
Instructions for Use
1. This product can be mixed with drugs or factors.
① Prepare the drug or factor solution, filter-sterilize it (0.22 μm), and transfer it into an empty luer-lock syringe.
② Connect the above syringe with this product 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 drug or factor solution.
③ 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.
④ It is recommended to mix 10 parts of ink solution with 1 part of drug or factor solution to prevent the gel properties after curing from being affected by excessively low product concentration.
2. Printing parameters are shown in the table below

3. 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.
4. 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.
