Faster printing means more products per day, but pushing speed too far degrades quality. Finding the optimal balance between throughput and quality is one of the most important decisions for any print farm operation.
How Speed Affects Quality
Higher speeds mean the nozzle moves faster, depositing material with less precision. At moderate speeds (40-60 mm/s), most printers produce excellent results. Above 80 mm/s, surface quality degrades as the motion system introduces vibration artifacts — ringing and ghosting become visible.
Layer Height Considerations
Thicker layers print faster but show more visible layer lines. For decorative collectibles, 0.16-0.20mm layer height provides an excellent balance of speed and surface quality. At 0.12mm, prints look smoother but take 30-40 percent longer. Ultra-fine 0.08mm layers are rarely justified for production.
Input Shaper Technology
Modern printers with input shaper calibration can print 2-3 times faster than traditional machines while maintaining quality. This technology compensates for mechanical vibration, allowing higher speeds without the ringing artifacts that normally appear. Our fleet uses input shaper on every machine.
Material Speed Limits
Each filament has a maximum volumetric flow rate — the amount of plastic that can be melted and pushed through the nozzle per second. Exceeding this rate causes under-extrusion regardless of other settings. PLA allows higher speeds than PETG. TPU requires the slowest speeds of all.
Production Optimization
At 3DCentral, each design has a tested speed profile that maximizes throughput without compromising quality. Simple geometric shapes tolerate higher speeds. Detailed figurines with fine features require slower, more careful printing. Matching speed to geometry optimizes total farm output.
