I have 17+ years of experience in 3d modelling, texturing, rendering, with focus on photorealistic renderings and 3d printing

As you can see in my portfolio, I use 3d to show my clients products, and I am a product designer myself, so I understand the issues and needs of my clients when it comes to product showcase. I just finished a NASA project with 5 stars. Check my reviews.
I have my own 3d printer, and when you approve the design, I can upload it to Shapeways, so you can order your finished prototype or send you the finished files.
Think of me as your own R&D Department in one person. I use 3d printing all the time. Have developed prototypes from faucets to construction tools to smartwatches and even spaceship tech.
