Best Budget PLA (Under $20)
We focus on consistency, finish, and value. This guide explains our test setup and the picks that stood out.
Summary
Budget PLA can be excellent for prototypes and batch printing. Our top priorities: (1) dimensional consistency (low variance across a 2 m sample), (2) spool winding quality (no cross-overs), and (3) surface finish with default profiles. If you only want one roll: choose a brand with steady diameter and a matte or semi-matte finish for hiding layer lines.
How We Test
We dry rolls to baseline (45–50°C, 6–8 hours), then print standardized coupons at 0.28 mm and 0.2 mm layers, 0.4 mm nozzle, and 205–215°C. We weigh spools to check net material vs. label, measure diameter every 10 cm over 2 m, and do quick bend tests on printed bars. We also print a simple vase and a calibration cube to evaluate ringing, corners, and sheen.
Top Picks
Value: a consistently-round roll that hits advertised weight and needs minimal tuning. Finish: matte lines that hide seams on functional parts. Workhorse: neutral colors with low stringing and predictable first layers. (Full brand notes coming in the live version.)
Recommended Settings
Start at 205–215°C nozzle, 55°C bed, 100% flow, 40–55 mm/s walls, 0.2–0.28 mm layers. First layer 0.2–0.24 mm with 105–110% flow helps adhesion. If walls look under-extruded, bump temp +5°C or reduce speed by 10–15%.
FAQ
Why are some rolls $5 cheaper? Lower-cost resin, looser QA, or aggressive promotions. What matters most? Roundness, even winding, and a vendor with steady batches over time.
