Recomendation for a Diy 3d printer
-
ok, thanks...
i have do test in my delta with 0.2 mm Nozzle, and the results are pretty good. But change nozzle when i d like to print small objects, and time that printer its doing these work (0.2 layers at speeds of 25 mm/sec).... the objects are small but time.... its looooongggg....
For this, its the main reason for have a printer for this kind of works....

I agree with Zapta, a good solid, single extruder, direct extruder, CoreXY is going to be one of the most precise options out there.

Have a look at this small form factor corexy

If you build the Voron, don't forget to ask for a serial number https://www.reddit.com/r/voroncorexy/

... and 0.9 degree steppers.
Another decision you will need to make is the pulley size, e.g. T16 vs T20. T16 will give you higher steps/mm but if it's not the default size for your design, you will need to make some adjustments to have the corexy belts parallel.
Here is an example of a hypercube evo downsized to 200x200x200 with a direct extruder. https://www.youtube.com/watch?v=bWggeeBoFs8

@zapta Thanks

Several people and one commercial supplier have made scaled copies of UMMD, my corexy printer, and by all reports they are as solid as the original.

And, I guess I should mention, because I am a HUGE fan of "Delta/Kossel", that second delta is also an option.
I do believe that Delta 3D Printers should ALL have the Duet "smart effector", and Hayden "mag ball" arms, and run a simple calibration at the beginning of each print. Given a "nozzle IS the probe" (like the smart effector) and "calibrate at print start", they can be incredibly fast and precise.
There is a reason that almost all factory automation belt pick, place, etc. are delta (or delta variants). These things cost big bucks and the designers could pick any kinematic. This is NOT sped up:

+1 for another Delta; if you don't need tool change or massive print volumes, they seem to give the best overall results and have simpler mechanics.
Also consider a Flex3drive or similar "remote direct" extruder system - one came with the Kossel XL+ frame kit I bought, and it is superb - really light, integrates directly with the Smart Effector and extremely precise!
Mine is used with the standard E3D threaded V6 hotend for the Smart Effector setup.

I used a fan setup from Thingiverse, it makes a very neat overall assembly:
