Project details
Getting a part from concept to printed object requires more than pressing export — the geometry must be watertight, the wall thickness manufacturable, and for multicolor work, the color regions correctly separated and assigned to the right filament slot before the file ever reaches the printer.
With 10+ yrs in mechanical design and product development, I bring engineering precision to every 3D print file I produce. I work in SolidWorks and CATIA natively, which means models are built with correct geometry from the start — not repaired mesh exports from artistic software.
What I deliver: color 3MF files optimized for Bambu Lab and other FDM printers, standard STL files for any printer, multicolor assemblies with filament slot assignment, STL error correction and mesh repair, conversion of sketches and 2D drawings into print-ready 3D models, and STEP or IGES exports where a manufacturing-grade file is also required.
What I do not provide: physical printed parts. All deliverables are digital files only.
Every project starts with a review of your reference material before work begins. Message me with your part description and I will confirm scope and timeline before you place an order.

Job Success
Bokaro, India - 6:33 am local time
With 10+ years in mechanical design and product development, a Masters in CAD/CAM, and a Top Rated track record on Upwork, I deliver precision designs that go straight to manufacturing without surprises. My edge is not just CAD proficiency — it is deep manufacturing knowledge in injection molding, sheet metal, and plastic part design, built into every model I create.
Core Services
-3D CAD Modeling and Design — From concept sketches to production-ready models across SolidWorks, CATIA, AutoCAD, and Fusion 360.
-Injection Molding and Plastic Part Design — Draft angles, wall thickness, and fully DFM-compliant geometry.
-Sheet Metal Design — Bend allowances, flat patterns, and tooling-ready drawings.
-2D and 3D Technical Drawings — GD&T, BOM, assembly guides, and manufacturing-ready drafts.
-DFM Reviews and Design Validation — Identifying and resolving costly errors before prototyping or tooling begins.
-Photorealistic Rendering — High-quality visuals for client presentations, marketing, and prototyping reviews.
-CAD File Conversion — Mesh to STEP/IGES, legacy file recovery, and cross-format compatibility.
Why Clients Choose Me
Every design is evaluated for real-world producibility, not just visual accuracy. My academic foundation in CAD/CAM combined with over a decade of hands-on industry experience means I approach each project with both technical depth and practical manufacturing awareness. I manage each engagement from initial concept through material selection, DFM review, and final production-ready deliverables — with an average response time under four hours and clear communication at every stage.

Steps for completing your project
After purchasing the project, send requirements so Ravi can start the project.
Delivery time starts when Ravi receives requirements from you.
Ravi works on your project following the steps below.
Revisions may occur after the delivery date.
Step 1 — Reference Review and Scope Confirmation
I review all uploaded reference material — existing STL, STEP, sketches, or photographs. I confirm whether the geometry is suitable for direct color application or requires rebuilding, and agree on deliverable format before work begins.
Step 2 — 3D Modeling or Mesh Preparation
Part is built in SolidWorks or CATIA with correct wall thickness and watertight geometry. If working from an existing file, mesh errors are corrected before color work begins.
