Introduction of Near Field Direct Writing Electrospinning Equipment M08-001 

- Two different printing methods of solution near-field direct writing and melt near-field direct writing can be realized on the equipment, and the solution nozzle or melt nozzle can be manually replaced according to actual needs; 

-  Near-field solution direct writing can prepare nanofibers with a diameter of 50nm-20μm, and near-field melt direct writing can prepare nanofibers with a diameter of 500nm-50μm;

-  Melt direct writing does not require the use of solvents, no solvent residues, environmental protection, and high efficiency;

-  Highly oriented nanofibers can be prepared by near-field direct writing electrospinning technology, andcomposite nanofiber materials with 2D or 3D structures can be printed;

- With exclusive patented technology, the printing accuracy can reach nanometer level, which is a powerful tool for micro-nano manufacturing.


Features

- The printing accuracy can reach the nanometer level, and the diameter of the nanofibers can be adjusted and controlled, which can meet the needs of different researchers.

- Melt near-field direct writing and solution near-field direct writing dual-function modules to achieve flexible configuration.

- Precise temperature control to solve the problem of yellowing of materials for long-term printing.

- Automatic calibration function, saving research time.

- The original software algorithm can design different arrangements of fibers, and the path can be controlled by modifying parameters.

- Support custom pattern printing, line and curve printing.

- Equipped with a high-definition camera to capture the printing process and details.

- The flat or tubular scaffold can be prepared with adjustable tube diameter, which can be used for cell culture or vascular scaffold.


Application  

- Near-field direct writing electrospinning machine can prepare biological tissue engineering scaffolds of ordered nanofibers to guide and stimulate the growth of bone, muscle, nerve tissue, etc.

- 2D or 3D electrospinning nanofiber composites have broad application prospects. In biomedicine, it can be used as drug control, wound dressing, biosensors. In terms of advanced fabrics, biodegradable textiles can be printed, and can also be used as catalysts in new energy batteries, electronic information technology, and microfluidic chips.
