The reason
Delta 3D Printers are
usually faster can, mostly be attributed to the
only moving part being the considerably lighter toolhead and its equally lightweight kinematics support structure whereas a
Cartesian 3D Printer will have to deal with both a print bed running on at least one axis that not only is heavier to begin with but gets heavier the larger and longer a print progresses posing some issues with calibrating it for resonances but also the toolhead running on another Axis with entirely different characteristics but still bound to the slowest denominator - The Print Bed.
IMHO,
CoreXY 3D Printers are somewhat the best of both worlds - A system like a
Voron 2.4 with its
Flying Gantry is essentially the equivalent of a Delta with a completely stationary print bed capable of brute forcing the speed ( I run
mine stock at
300mm/s with almost 6'000 Accel = 29min Benchy ) by simply using beefy Steppers on the essentially identical X/Y Axis with the added benefit of not having the vertically wasted space of a Delta.
As far as I'm aware - Deltas
also aren't exactly a prime candidate for 3D printing Parts requiring high precision - Something, something about their Kinematic System being iffy making things
both perfectly straight and/or round 🤔
