I will edit step or stl files or design custom 3d lattice structure for 3d printing

About this gig
Is your 3D printed part too heavy, wasting expensive material, or failing due to poor heat dissipation?
Many engineers face the same issues: your file is too heavy, your slicer cannot generate complex internal structures, or you are stuck trying to edit a rigid mesh file without the right tools.
Whether you need to edit a STEP or STL file or generate a lightweight structure from a blank canvas, I am here to solve those bottlenecks. As a lattice engineer, I convert solid volumes into optimized, manufacturing-ready cellular geometries.
️ What I Can Design From Scratch
- TPMS Topologies: Gyroid & Diamond structures for heat exchangers.
- Truss Networks: Cubic & Octet structures for mechanical stiffness.
- Graded Lattices: Variable-density porous designs for medical implants.
- Product Infills: Flexible, shock-absorbing lattices for footwear.
File Editing & Modification
- CAD Modification: Edit STEP file data to add internal lattices.
- Mesh Repair: Clean up and edit STL meshes to fix slicing errors.
- Light weighting: Remove volume while maintaining structural strength.

I am a CAD designer specializing in 3D modeling, technical drawings, and sheet metal design for 3D printing and manufacturing. I help engineers, startups, and product creators turn ideas into accurate, production-ready designs using SolidWorks and industry-standard tools.
I deliver precise 3D CAD models, detailed engineering drawings, and DXF flat patterns with proper dimensions and tolerances. My focus is creating functional designs ready for prototyping and fabrication.
Expect clear communication, fast delivery, and reliable results. Send your idea or sketch—let’s bring it to life.
FAQ
What file formats do you accept, and what do you deliver?
I accept standard CAD and mesh formats, including STEP, STP, STL, OBJ, and 3MF. I will deliver fully closed, manifold, and print-ready files in the exact format your project requires (typically STEP or STL).
Can you edit an existing STL file that I already have?
Yes! Editing STL mesh files is highly difficult, but I specialize in mesh repair and editing STL meshes. I can hollow out your model, clean up defects, and integrate custom internal lattice structures seamlessly.
What types of 3D lattice structures can you design?
I design advanced TPMS topologies (Gyroid, Schwarz, Diamond) for heat dissipation and fluid flow, Truss-based networks (Cubic, Octet, Isogrid) for mechanical strength, and graded or variable-density lattices for aerospace and medical implant optimization.
Will the lattice structure be ready for 3D printing without slicing errors?
Absolutely. I engineer production-ready, manifold geometries tailored to your specific additive manufacturing process (SLM, SLS, SLA, or FDM). The files will slice cleanly without crashing your software or causing print errors.
Why should I message you before placing an order?
Every engineering part has unique structural, weight, and material requirements. By messaging me first, we can discuss your goals, review your files, and ensure you select the correct pricing package for your project.
