Iranian Firm Manufactures Modular 3D Bioprinter

An Iranian knowledge-based company has managed to design and produce a modular 3D bioprinter used to produce body structures.

“This advanced technology has created a significant change in treatment methods and improving the quality of life. The modern 3D bioprinters are known as the pioneers of this area, and their work process includes the use of biological inks that are stored in special cartridges and produce the structures needed by the body through needles embedded on the platform,” said Mahmoud A’zami, the managing director of the knowledge-based company.

“Our company’s modular 3D bioprinter is made by metal sheeting method, and in addition to its beautiful appearance, it offers user-friendly performance and is compatible with complex print mechanisms,” he added.

“One of the basic challenges in designing this printer is the need for changing various extruders, and now, thanks to the use of modern mechanisms, this process can be easily done and allows users to apply the device without wasting time,” A’zami said.

Iranian Knowledge-Based Firm Produces Main Ingredient of Perfumery

Iranian researchers succeeded in obtaining a formulation for production of a key type of flavoring and preservatives for application in pharmaceutical and food industries.

The main ingredient of rose water is 2-phenylethanol, which is used in various industries, including perfumery, pharmaceutical and food industries, and is considered as one of the knowledge-based achievements of this company. This product was produced through a new laboratory method and has received a science-based award for it.

2-Phenylethanol is one of the main components of many perfumes due to its sweet and floral smell. This substance gives depth and richness to perfumes and increases the durability of their smell, and it is also used as a preservative and antibacterial agent in the pharmaceutical industry. This substance helps to increase the shelf life of medicines and prevents the growth of bacteria.

2-Phenylethanol is used in the food industry as a flavoring agent for some food products and gives them a pleasant aroma and taste.

Iranian Specialists Manufacture Laser Engraver

Iranian researchers at a knowledge-based company succeeded in building an ultra-advanced ultraviolet laser engraving machine with the capability to engrave very finely (less than 5 micrometers) on all types of metals and glass.

The device uses NdYvO4 blue longitudinal blowing technology and LBO crystal to produce ultraviolet laser (355 nm) through a non-linear optics process. This laser is more refined than conventional lasers due to its much higher quality and shorter wavelength.

Ultra-advanced ultraviolet laser engraving machine is used for optical, polymer, semi-conductor and household appliances and medical industries.

The possibility of domestic repair and support and the ability to optimize the device is one of the technical advantages of this product compared to its foreign counterparts.

Iranian Company Produces Nano Material Resistant to Impact
