Does size and printing speed matters?

Phantom team has been working on a fastest plastic 3D printer already over a year. Promising was to launch up to 1.7 times faster 3D printer with no negative impact in printing quality, but we found a better way to increase printing speed. There for it is interesting if speed really matters? Also we have issue by questing printing size. Our current printing field is 50 cm X 50 cm X 50 cm (19.685 inch X 19.685 inch X 19.685 inch). We thought for a high speed 3D printer using smaller printing field would be a sin.
Would like to hear more opinions. Lets discus about this :confused::)

If Printer A takes 5 hours to print something and Printer B takes 1 hour to print the same part with the same quality, assuming ALL other factors remain the same, most people will buy Printer B.

For the same printer, the speed is inversely propotion to the printing quality.

Larger nozzle can "bypass" to an extent... you can save an tremendous amount of time. Also, layer height optimization is a major factor to finish a print earlier.

The speed alone as "printing speed" is a freaking killer to aesthetic, you will see imperfection due to those small blobs on your object. Unless you sand it, acetone bath it, etc, I tend to avoid increasing the print speed.

Many 3d Pritner MFG are claiming we are so fast etc etc, sure some are fast, however in reality to be noticeable fast, the quality needs to be good also.
Certainly many factors needs to be considered, however as of current if your machine manage to make the liquid to solid form (with really good quality, no blobs or other strange thing) in less than seconds and have hardware that can calculate those fast data, we will see a winner. 20 cm may take 50 hours to print with very high detail. Do teh same job in 5 hours and you will sell like crazy.

Yes, for sure. Size and printing speed matters. If the size of pring is too small then anyone will find very difficulty in reading it. Same as, if the speed of printing is too slow, then all the process will go slow.

Print speed does matter, but quality also matters, there is a trade off. It is the same with our conventional printer, I can set it to print in Draft, Normal or Best quality. The speed with which it prints out is, as
wenganxiang says inversely proportional to the quality of the print.

As 3D printing technology evolves the overall print speeds will reduce but this relationship will stay the same. For example, one can reduce the z-layer height, increasing the resolution of the print but it will take longer.

Which is more important, quantity vs quality, the answer is they both are depending upon the context. Those initial development prints you want it quick and dirty and then, once the settings are right and the model works you go for the quality.

Simply put, everything is a compromise between speed & quality.

I think there are a couple of printers in the works that use the uv set 'ink'/resin.
But with fff style rointing

If you could set the resin fast enough then because the actual material is a liquid, you could print really fast with decent quality.
It's also a much better system then the sla based resin printers.

But simple material properties of the plastics will always limit the speed of an fff machine.

Undoubtedly, size matters. Yesterday, I shrank a model and tried to printed it, buy the printing is horrible because it was so small that the nozzle melted the model. Also, the speed can influence the printing quality. If the speed is too high, the filament will not be extruded timely and you will get a poor printing.

Would someone please point me to a discussion/ article on layer height optimization?
