I will optimize, hollow, and shrink stl files for 3d printing
McBarry
About this gig
Is a heavy or solid STL file slowing down your slicer or wasting your 3D printing material?
Large, unoptimized 3D models can crash your slicing software, take endless hours to slice, and waste expensive resin or filament. Whether you need to reduce a dense polygon mesh or hollow out a solid model for SLA/resin printing, I will prepare your files for a fast, material-efficient, and flawless print.
From detailed character sculpts and cosplay props to functional parts and miniatures, I optimize your STL files while preserving maximum visual detail.
What I offer:
- SLA/Resin Hollowing: Precise hollowing with strategic vent/drain holes to prevent suction cup failures and trapped resin.
- File Size & Polygon Reduction: Mesh decimation to shrink massive, laggy STL files without losing sharp surface detail.
- Wall Thickness Optimization: Uniform wall adjustments to ensure structural strength and prevent cracks or warps.
- Manifold & Error Checks: Ensuring your optimized mesh remains completely watertight and 3D print-ready.
Why work with me?
- Save money on resin and filament on every print
- Prevent slicer crashes and speed up print times
- Fast turnaround and clear, professional communication

Hi, I'm McBarry, a 3D printing specialist focused on repairing and optimizing STL files for reliable, high-quality prints. Whether your model has mesh errors, non-manifold geometry, holes, or other printability issues, I provide clean, accurate fixes that are ready for production. I value clear communication, attention to detail, and on-time delivery, ensuring every file meets your expectations. My goal is to help you bring your 3D printing projects to life with confidence.
FAQ
Why should I hollow my 3D model for Resin (SLA) printing?
Hollowing your model significantly reduces resin consumption (saving you money) and lowers overall print weight. More importantly, it decreases suction force on the FEP film during printing, which greatly reduces the risk of layer separation, warping, and print failure.
Will reducing the file size (decimation) lower the visual quality of my print?
No. I use smart mesh decimation techniques that reduce high-density polygon counts in flat or smooth areas while preserving fine edge details and sharp textures. Your slicer will load much faster, and the physical print quality will remain pristine.
Where will you place the drain holes for resin hollowing?
I strategically place drain/vent holes in flat, non-visible areas (such as the bottom of the base or hidden joints) so they don't spoil the surface detail. If you have a specific location preference, just let me know when submitting your requirements.
What wall thickness do you recommend for hollowing?
For most standard SLA/Resin prints, a wall thickness between 1.5mm and 2.5mm offers the best balance of strength and material savings. For larger models, I can reinforce internal walls or adjust thickness based on your specific printer and resin type.
Can you optimize files for FDM (Filament) printers as well?
Absolutely! For FDM printing, I focus on polygon reduction to prevent slicer lag, repairing non-manifold geometry, and ensuring wall geometry slices cleanly without paper-thin voids.
