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 - 12:07 am local time
Ten years of mechanical design and product development, a Masters in CAD/CAM, and a proven record delivering for clients across the US, UK, Europe, and Australia. My work does not stop at a clean model. It starts with understanding how your part will be made, what it will cost to manufacture, and where the design will fail before a single tool is cut.
Core Services
3D CAD Modeling and Design — Concept to production-ready geometry in SolidWorks, CATIA, AutoCAD, and Fusion 360, built to your exact manufacturing process.
Injection Molding Design — Wall thickness, draft angles, parting line strategy, and full DFM compliance from the first revision.
Sheet Metal Design — Bend allowances, K-factor calculations, flat patterns, and tooling-ready documentation.
Technical Drawings — Complete 2D drawings with GDT, BOM, and assembly instructions to ISO and ASME standards.
DFM and DFA Analysis — Catching design problems before they become expensive tooling changes.
Photorealistic Rendering — Studio-quality visuals for presentations, crowdfunding, and pre-production reviews.
CAD File Conversion — Mesh to solid, legacy formats to STEP or IGES, cross-platform compatibility.
Why Clients Choose Me
DFM thinking is built into every model from the first sketch, not added as an afterthought. Academic grounding in CAD/CAM combined with a decade of real industry experience means I bring both technical precision and shop-floor practicality to every project. Average response time under two hours. Clear milestones. No surprises at delivery.
Industries Served
Automotive, Consumer Products, Industrial Equipment, Robotics, Aerospace, Medical Devices.

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.
