Hello! My name is Mateus Dias, and I am a Mechanical CAD Designer specializing in 3D modeling, mechanical design, product visualization, and manufacturing-ready technical documentation. I work with a wide range of engineering and industrial projects, delivering precise, clean, and functional CAD models for manufacturing, prototyping, and product development. I support clients in: 3D CAD modeling of mechanical parts, assemblies, consumer products, mechanisms, sheet metal, machined components, plastic housings, and industrial equipment Technical drawings (2D) with full dimensioning, tolerances, sections, exploded views, and manufacturing notes Product visualization & rendering for marketing, catalogs, and presentations Design for Manufacturing (DFM) for CNC machining, sheet metal, injection molding, 3D printing, and welding Mechanism design (rotary systems, sliding systems, dampers, tension devices, retractable systems, hinges, etc.) As-built corrections, industrial layouts, piping elements, and general technical revisions Prototype development, including geometry validation, part splitting, tolerances, and print-ready files ✔ Software Expertise SolidWorks Siemens NX Solid Edge DraftSight Blender KeyShot / Marmoset 3D printing preparation tools ✔ Why clients choose me Strong mechanical background High attention to detail Clean, organized CAD structure Fast communication and reliable delivery Experience with both engineering projects and visual/marketing renderings Ability to take a concept and turn it into a fully functional, manufacturable solution ✔ Project Types I specialize in Industrial machinery and mechanical components Furniture mechanisms and retractable systems Plastic housings and consumer products Sheet metal and structural assemblies Rotary systems, sliding assemblies, gear mechanisms Product visualization for catalogs and brand materials 3D printing prototypes (FDM, SLA, SLS) Full CAD packages (3D + 2D + BOM + renders) If you need a precise, reliable, and detail-oriented CAD designer for engineering or product development, I’m ready to support your project from concept to manufacturing. Let’s build your project together. — Mateus Dias | Diaz CAD Studio
