We have always been a fan of Igor Knezevic's work ever since we attended his panel at the 3D Printer World Expo.  He is an award winning Architectural and Film Concept Designer who works out of Los Angeles, CA.  His work ranges from architectural to fashion design, with an impressive resume in the movie industry for hi Film Concept Design work - IMDB link here.  You can find his work on and various 3D Printing Expos around the world.  Check out out interview below with our interviewer, Victoria Saha:

VICTORIA: You have been a designer for more than 15 years, what interested you the most about 3D printing to collaborate your designs with it?

IGOR: Yes… I work using 3D applications for many years so that going into 3D printing was very natural to me. For me, the fact that I can now have real physical object in my hands done from almost any given crazy geometry I created was amazing…. And irresistible. One becomes kinda jaded just doing virtual objects in 3D. All that looks good on the screen but real experience of designed objects only happens when you can use them and work them directly.

I’d say getting access to good 3D printing tech was one of most important events for me in last 10 years. It really changed the way I design.

VICTORIA: I know that you won a Merit Award for a 3D printing design contest, what went into designing the winning piece?

IGOR: These 3D printed wearable pieces (mostly very sleek and modern looking jewelry) are designed with material properties in mind. In this case this is SLS nylon (PA12 Nylon Polyamide). I work a lot with that material and it has amazing properties especially the flexibility (bendability) if it is printed in thin cross section. So by using that property what was designed was able to be all printed in one piece without needing hinges or pieces made from other materials. It simply can wrap around the wrist or upper arm on its own.



VICTORIA: What challenges do you come across when coming up with a design?

IGOR: For objects that I want to try to sell, number one issue is price of printing. I believe one has to be pragmatic and realistic if you are trying to make business of this. One has to work within current constraints. On the other hand some other pieces I create, for example for films, these do not have such constraints. But, there is difference in how I approach these tasks. Doing a design to be used in film is basically a gig you need to do within the given deadline and you will need to cut corners to meet that deadline. My own designs… that I create to fulfill the vision I have. But hey…. I try to keep it reasonable.

VICTORIA: Is there a design that you have felt was just impossible to create?

 It did happen… but when it happens it is mostly because my expectations for specific material were not realistic. I try to approach designing 3DP objects by working it backwards. I try to take constraints of material and price into account. So that rarely happens. However… many more times what happens is that it prints OK but then you realize it is not structurally OK as you thought it would be. So… back to 3D CAD… rework…. Print again. Trial and error.


VICTORIA: Were you surrounded by technology a lot while you were growing up?

IGOR: I grew up in Ex. Yugoslavia in 70s. Not much technology back then anywhere… but I did get one of first micro-computers made in Europe called ZX Spectrum in early 80s, and it probably was one of first “personal” computers in town at that time. So then I went and learned how to do some Basic coding in BASIC. It all started from there.

VICTORIA: Where do you envision 3D printing going in the next few years?

I am hoping there will be good quality SLS and SLA printers cheap enough to get one at home. But… what I really need are repeatable and consistent quality. Current FDM printers, IMO, have problem of fairly substantial number of misprints.

I also hope there will be good local printing services that will provide good finishing, coloring and maybe event packgaging and shipping etc.

VICTORIA: If 3D printing wasnt availabe what route do you think you would of taken to bring this designs to real life?

IGOR: Most likely some other digital manufacturing tech. I did do fair amount of work with Laser-cutting and water-jet cutting.

Some very cool things can be made with it.
