I am a Mechanical Engineer and CAD Expert with experience of 7 years As a dedicated full-time freelancer, I provide Product Development and Reverse Engineering services to clients. Products and 3D CAD Models including Sheet Metal Designs, 3D Printed Designs, Composite Designs, and Plastic Designs (Injection Molding, Thermoforming). The designs are Validated using Simulation and Mechanical Analysis along with the selection of appropriate materials, and enhance overall design quality. Following prototyping of the Products, I provide comprehensive manufacturing drawings alongside compelling rendered images and animations that vividly showcase product and the assemblies. My approach is driven by efficiency, both in terms of design timelines and costs. I integrate pre-existing manufactured parts and components from a spectrum of suppliers into my designs. By doing so, I ensure not only economical design execution but also preemptive mitigation of redundant manufacturing expenses. All this is presented with meticulous detail, including material selection, Bill of Materials (BOM), and accessible sourced links. In Tight Tolerance Project, I implement Tolerance Analysis in Assembly Design, where I adhere to ISO 286 and ISO 2768 Tolerance standards. For accurate and precise manufacturing, I use ASME Y14.5 GD&T in manufacturing drawings. Feel Free to contact me regarding your project and I will be glad to share my insight. My diverse project history includes: • Product Design encompassing metal, plastic, and composite materials • Designing 3D Printed Components • Plastic Injection Molded Designs • Automotive Parts with Precision • Sheet Metal Designing • Composite Mold Designs • Plastic Design Solutions • Part Designs for Machining Processes My capabilities also extend to the domain of transforming 3D Scans into robust 3D CAD Models: # 3d Scan Alignments and Registration/Merging # 3d Scan Data, Mesh Data and Point Cloud Data optimization # Conversion of 3D Scan Data to 3D CAD Model # STL, XYZ, PLY to STEP # Accurate CAD Model with Deviation Analysis # 2D Drawings from 3D Scanned Data # Area, Volume Calculations, and Inspection of 3D Scan Data # 3D Scan and 3D CAD Comparison report # 3D Scan Data to Assembly model # 3D Scan to Mold Designs of parts Mechanical Analysis and Simulations; 1. Design Strength analysis to find the factor of safety under loads. 2. Structure Designs Analysis for Load distributed to Foundation. 3. CFD Analysis for Drag, lift forces. 3D Printed Parts: # 3D Printed Enclosures or Casings for Electrical and Electronic PCB devices # 3D Printed Gadgets # 3D Printed parts for Machines such as gears, brackets. # 3D Printed parts for Products and Prototypes Softwares I use; 1. SolidWorks / SolidWorks Simulation 2. Catia 3. Geomagic Design X 4. Meshmixer 5. Creality Slicer 6. Keyshot Deliverables: 1. .OBJ, .STL .STEP, .IGES, X_T (Parasolid) etc formats 2.
