I studied visual arts and developed my skills as a creator of tridimensional objects since very early in my formation. Having specialized in Digital Sculpture for organic objects, and Parametric software of CAD for precise prototyping of functional objects as well, the software I use ranges from Pixologic Zbrush to Dassault Systèmes Solidworks. I work from my 3D printing studio where I have many 3D FFF and DLP printers working to help professionals on their projects. I believe that best way to create is to know what the public and clients need, what they want to express and how any medium will convey all this information in the best possible way, a 3D object, a character, a logo, an animation, or a video are some of the best options to answer these needs. Please feel free to message me for any questions. I will be glad to work with you and create long term working relationships. Thank you https://www.artstation.com/lindorfe ít hơn
