3Dprinters are evolving and the features I look for are speed, precision, part appearance, part removal and printer cost.
Most printer produce accurate prints and minor faults can be adjusted out with a good slicer.
But most printers are slow, painfully slow.
Bed heat up, print speed, bed cool down, part removal and bed prep for next print are all factors that affect print time.
We run parts for light production in business to business applications.
Users in this arena are tolerant to 3Dprinted parts and even admire them as cool new technology.
We build products that could never be economically built using injection mold.
Here are my thoughts from a production stand-point....
We use Prusa MK3 printers with PETG filament.
The Prusa bed size is just right to build one or several parts.
Too many parts on a bed increases print time; two small printers will print twice as fast as on large printer for multiple parts.
We have a small print farm with four Prusa MK3 printers running 10-hours a day.
The Prusa is $900 (1+) and can add more with demand.
These little machines are perfect, because...
Prusa also has a precise and accurate and provides their own Slicer with advance features.
The printer has a magnetic removable flex build plate.
The flex plate has an orange peel texture that has a nice appearance.
A removable flex plate also enhances speed, since build plate cooling is not required for part removal.
The removable textured flex plate is a must for speed and appearance.
The printers were modified.
The filament spool is mounted on a remote rack while in use and stored in dryer each night.
The hot end of the Prusa was replaced with a Mosquito magnum and heater.
The Magnum increases the max volumetric speed for PETG from 8 to 20 mm3/s +.
This is a huge increase in print speed for large models.
What took 8-hrs to print now takes 5-hr and we can make two runs in a shift.
The best part is a used Prusa is easy to re-sell on ebay.
As new printers with the latest features are available, we can replace the whole lot at a low cost.
Just my thoughts on this subject.
