Interview with K Line Europe founder Dr. Sherif Kandil



We all heard about 3-D printing, what does 4-D stand for?

Yes, that is true that we have been hearing lately only about 3-D printing, nowadays 4-D represents the dimension of time. 4-D refers to additive manufacturing or printing of special materials that have certain memory characterisation built in a specific layering system on a 3-D printer, yet was designed or using CAD on a software that dictates the material reshaping and response to stimuli by time.

Can you tell us more about your recent activities in concern to 4-D technology?

After I patented the idea of 4-D printing in orthodontics, I moved on to applying this technology in our R&D labs in K Line Europe in Düsseldorf, Germany. 4-D printing technology has been shifting engineers’ opinions and even many in the medical field on the possibilities and chances that have been unleashed after the introduction recently of this technology. I have been focusing on applying this
