3D PRINTING HEAD TO PRINT WITH VISCOUS MATERIALS PROJECT
The article is analyzing possibilities to design and use 3D printing head which would have an ability to print with viscous materials. Possibilities to regulate debit of ejected viscous material with pressure or by volume methods are analyzed.
Research includes analysis designs of known 3D printing heads to print with viscous materials; review of their advantages and difficulties to use. Experimental research on specially produced laboratory equipment and designed 3D printing heads are presented. Main tests were done using liquid ceramics.
Viscoelasticity of ejected material, printing and material flow velocity are main parameters possible to variate to get quality prints. Very big attention to drying process of ejected material needs to be paid.
