Print Speed vs Quality: Finding the Sweet Spot

The Speed-Quality Tradeoff

Faster printing means more output per day. But push too fast and quality suffers. Here's how to find the right balance.

How Speed Affects Quality

At higher speeds, you get: more vibration artifacts (ringing/ghosting), worse overhangs, more stringing, and potential layer adhesion issues.

Modern printers like Bambu Lab handle 200+ mm/s cleanly. Older printers struggle above 80mm/s.

Speed by Use Case

Prototypes: Print fast. Quality doesn't matter. 150-300mm/s with thick layers.

Functional parts: Medium speed. Strength matters more than looks. 80-150mm/s.

Display models: Print slow. Surface quality is everything. 40-80mm/s with fine layers.

Production runs: Find the fastest speed that maintains acceptable quality. Test once, then replicate.

The Hidden Cost of Slow Printing

Printing at 50mm/s instead of 150mm/s triples your print time. That means 3x the electricity, 3x the depreciation, and 3x the opportunity cost.

A part that takes 2 hours at 150mm/s takes 6 hours at 50mm/s. If you're selling prints, that's 4 hours you could have used for other orders.

Finding Your Speed Limit

Print a test model (like a speed boat benchy) at increasing speeds. Find the point where quality becomes unacceptable, then back off 20%.
