Choose a 3D printer?

Question

3D

Greetings!
I got the idea to get a 3D printer. So far, I am studying materials, reviews, blogs, but some wishes have already been formed. In principle, I can choose everything myself, but I want some additional confidence with the choice from people in the subject. There will be a million questions. :)
The goal is for myself, I don't think that I will print for sale.
So, wishes:
- I plan to take it on Ali, because. the prices that our sellers break are much higher, which is a real sin, of course;
- budget: no more than 30.000 rubles (well, no more than 35.000 with delivery);
- not a delta (I've read that they can get stuck with calibration and a rather painful setting, plus I want a non-round print volume);
- print volume: in width / length, I think an A4 sheet will be enough, and in height - let it be at least 20-25cm;
- a metal frame with metal profile fasteners (it hurts to look at the plastic corners);
- if possible, support for the largest possible type of plastics for printing;
- extruder: 1 piece;
- table heating;
- printing from a card;
- as far as I understand, a rail drive is better than a screw drive, and even more so a belt drive;
What is not completely clear at the moment:
- what type of mechanics is better - a movable table or a movable head along XY (IMHO, a movable head is better, because the printed part will not be subjected to stress);
- it's not very clear - a closed or open case is better (if anything, I can make the casing myself);
There is one nuance. On Ali for a little more money (+ 5-10k to the indicated amount) there are types of universal machines, which, in addition to printers, can also be laser engravers / cutters. Let's say if I want to cut plywood no thicker than 3-4mm - how viable will such a device be? Will it give normal printing/cutting/engraving accuracy? Or is it easier to take 2 devices separately? Or one, but with the prospect of installing a laser head? The presence of such an opportunity is not essential, but it would be nice.
And another nuance. I can quite assemble the printer myself - I can screw / solder / flash it without any problems. But I saw only a couple of more or less intelligible instructions. Is the game worth the candle with such a budget (a bunch of separate orders, nothing to miss, everything to choose correctly, etc.)? How qualitatively more serious device can be assembled independently for such money?
I'm not in a hurry with the choice, I plan to buy by the end of the year.
At the moment, an approximate list of candidates looks like this (in principle, there are only about 10 models for this money):
- TEVO Black Widow ( https://ru.aliexpress.com/item/2016-Newest-TEVO-Bl... ) ;
- Flyingbear-Tornado ( https://ru.aliexpress.com/item/2017-Newest-Large-P... );
- Creality 3D(https://ru.aliexpress.com/item/Big-Print-Size-400-... );
- SoMars S6/S6-Plus ( https://ru.aliexpress.com/item/2017-S5-3D-printers... );
- JGAURORA (as I understand it, this one is based on Prusa) ( https://ru.aliexpress.com/item/WHY-NOT-Print-Your-... );
- Micromake ( https://ru.aliexpress.com/item/2017-Nieuwste-3D-Pr... );
- option with engraver: WINBO ( https://ru.aliexpress.com/item/3D-Printer-with-Too... );
Thanks in advance for your replies and recommendations.

Answer 1

Not a profile res - go to 3dtoday.ru - there are such questions twice a day))))
Links are all broken.
Take https://www.zav3d.ru/ - at least it won't drop much in price

Answer 2

I took myself a Chinese ult. https://supereyes.ru/catalog/3d_printery/3d_printe... Absolutely satisfied with the printer. This does not mean that it does not have shortcomings, but for my amateur tasks its capabilities are quite enough.

Answer 3

If you want a really good 3D printer, then take the Japanese Roland https://engraver.ru/ or something like that, it certainly costs more than Chinese ones, but you really need a really high-quality 3D printer, it won’t work differently.
