About this service

Stop struggling with uneditable mesh files and "unprintable" geometry. I provide professional Mechanical Engineering services to transform your concepts, 3D scans, or broken STL files into high-precision, production-ready CAD models.

Whether you need a custom enclosure for a PCB, a replacement mechanical gear, or a complex assembly, I engineer every file with Design for Manufacturing (DFM) principles to ensure a perfect print the first time.

What I Specialize In:
1. Advanced Reverse Engineering (Mesh to CAD)
STL / OBJ / PLY to STEP: I don't just "auto-surface." I manually rebuild your mesh into a clean, parametric SolidWorks model.
Modification & Repair: Need to change a hole diameter on an STL? I can modify existing mesh files and export them as editable CAD data.
Deviation Analysis: Ensuring the digital model perfectly matches the physical dimensions of your original part.

2. Engineering for 3D Printing (DFM)
Tolerance Management: Custom clearances (0.1mm - 0.3mm) based on your printer type (FDM/SLA/SLS) so parts snap or bolt together perfectly.
Structural Optimization: Adding ribs, fillets, and correct wall thicknesses to prevent warping and ensure mechanical strength.
Complex Enclosures: Designing waterproof (IP68) or ventilated casings with integrated mounting points for electronics and batteries.

3. Mechanical Simulation & Validation
FEA Stress Analysis: Testing your design under load in SolidWorks Simulation before you waste filament or resin.
Mechanism Design: Cre... read more

FEA Stress Analysis: Testing your design under load in SolidWorks Simulation before you waste filament or resin.
Mechanism Design: Creating multi-part assemblies with functional joints, gears, and linkages.

Deliverables You Will Receive:
- Production Files: High-resolution STL and 3MF optimized for slicing.
- Engineering Files: STEP, IGES, or X_T for CNC machining or future editing.
- Source Data: Original SolidWorks (.SLDPRT / .SLDASM) files upon request.
- Technical Drawings: 2D PDF/DWG drawings with dimensions and tolerances. read less
