PETG is the next step up from PLA: better heat resistance (80C vs 60C), stronger layer bonds, and slight flexibility that prevents brittle snapping. It is the default recommendation for functional parts that see any heat or stress. Polymaker PolyLite PETG ($22/kg) prints as easily as their PLA while delivering genuine engineering improvements. The key to good PETG: dry filament and slightly higher temps. Print at 230-245C with the bed at 70-80C. If your PETG is stringing badly, it is almost certainly a moisture issue. Invest in a filament dryer or use the Bambu AMS 2 Pro's built-in drying. Polymaker, Hatchbox, and eSUN all make good PETG. The differences between premium PETG brands are smaller than PLA. Pick whichever is cheapest and available. For enclosed printers like the P2S, P1S, or Core One, PETG prints beautifully with zero draft issues. Open-frame printers may need a simple enclosure (even a cardboard box) for best results in cooler environments.

ABS and ASA are the workhorses of functional 3D printing: UV-resistant, heat-resistant to 100C+, and strong enough for automotive and outdoor applications. ASA is essentially ABS without the warping headaches and with better UV stability. Polymaker PolyLite ASA ($25/kg) is our top pick. It prints at 240-260C with a bed at 90-100C. An enclosed printer is mandatory for ASA. The P1S, P2S, Core One, or any QIDI enclosed printer will handle it. Open-frame printers will warp. eSUN ABS+ ($18/kg) is the budget alternative. The '+' formulation reduces warping compared to standard ABS. If you are on an enclosed Ender 3 with a DIY enclosure, eSUN ABS+ is forgiving enough to work. For UV-exposed outdoor prints (garden decorations, exterior fixtures, car parts), ASA is the clear choice over PLA or PETG. A birdhouse printed in PLA will deform in summer sun. The same birdhouse in ASA will last years.

Engineering filaments require an enclosed printer with active chamber heating: Bambu H2D, X2D, Prusa Core One, QIDI Q1 Pro, or QIDI Q2. These filaments print at 260-300C+ with chambers at 50-65C. They are not beginner-friendly but produce parts with mechanical properties approaching injection molding. Polymaker PA6-CF (Nylon 6 with carbon fiber, $45/kg) is the best carbon-fiber filament available. It produces parts with exceptional stiffness and heat resistance up to 180C. Use it for drone frames, automotive jigs, and industrial prototypes. Prusament PC Blend ($38/kg from Prusa) is the best polycarbonate for desktop printing. Transparent, impact-resistant, and heat-resistant to 110C. Prusa designed it specifically for their printers, and the profiles are dialed in perfectly. All engineering filaments are hygroscopic. They absorb moisture from the air and print terribly when wet. A filament dryer is not optional, it is required. The Bambu AMS 2 Pro's built-in drying is the most convenient solution. Standalone dryers from Sunlu or eSUN cost $40-60 and work well.

Resin printing uses liquid photopolymer instead of filament spools. The material cost is higher per unit but the detail is unmatched for miniatures, jewelry, and dental models. Elegoo Standard Resin ($25-30/kg) is the default starting point. Available in dozens of colors, it cures reliably on Elegoo, Anycubic, and Phrozen printers. The results are smooth, detailed, and consistent. Start with gray: it shows detail best under any lighting. For miniatures and tabletop gaming, Siraya Tech Tenacious ($40/kg) blended 50/50 with standard resin produces parts that survive drops and rough handling. Pure standard resin is brittle. The Tenacious blend adds just enough flexibility to prevent shattering when a miniature falls off the table during game night. Safety note: resin is toxic before curing. Always wear nitrile gloves, work in a ventilated area, and never pour uncured resin down the drain. A wash and cure station ($100-150) is essential. The Elegoo Mercury X or Anycubic Wash & Cure Plus handle both washing and UV curing in one unit.
