High-Finish Prototype 3D Print

I have a completed STL/STEP file and need it printed exactly to scale for a display model. Visual quality is key: the surface must be smooth enough that a quick pass with fine sandpaper lets me move straight to paint. FDM or resin is acceptable—choose the process you feel gives the cleanest result, high-detail layer height and a structural infill that prevents any sagging or warping. Preferred colour is a uniform matte black, white, or grey. Dimensional accuracy should stay within ±0.2 mm across the entire piece. Once the print is finished, please handle basic post-processing (support removal, light cleanup), pack it securely, and ship to Kolkata, West Bengal. Include courier and packaging costs in your quote along with your estimated turnaround time. Deliverables • One full-scale print (no scaling) in the colour specified • Post-processed surface ready for light sanding and paint • Tracked shipment to my Kolkata address Acceptance will be based on fit to the supplied file, surface smoothness, and safe arrival. Share a few photos of previous prints that show similar finish quality when you respond. Looking forward to working together. Budget: INR 600–1250
