The use of a new printer, which combines the simplicity of construction with almost unlimited possibilities of work with photo-cured bioinks, opens up a new chapter in the testing of materials which we create by us. The construction system of this device does not limit but gives the possibility to create new variations in terms of materials. The printer has been used for experimental work using new photoinitiating systems, new photo-cured gels, and new photo-cured nano-composites tested for biomedical applications.
