but get a e3d or clone hotend and a Bowden extruder. plus Skynet v2 auto leveling with an induction sensor. makes it print much better and easier to sort out clogged hotends.

There are many "bargain priced" printers out there that become "projects" and require upgrades and require more expertise to get them going and keep them working well. These are not good "first" printers. New users often purchase these to save money and end up becoming disenchanted with 3D printing.

Choose wisely. There are many reviews on utube and elsewhere.

Here, a guy cuts 1/4-inch thick plywood with a 3D printer. By attaching a "Dremel-like" tool, and using a high-speed bit, he was able to easily cut plywood. As a demonstration, he cuts a square out of the 1/4-inch plywood, and the cutting bit makes several passes in the same shape to cut away another layer with each pass.

I recall Grinhill cut aluminum sheet with a router, and he said you need a high-speed cutting bit, and a slow feed rate, but when doing that, there were no issues.

I watched the cutting a motor mount video a couple days ago.

The majority of 3D printers (especially low cost) are not very "stiff" because they don't need to be. CNC machining generates recoil forces that are problematic as they require more machine stiffness. The chips generated are also problematic for the moving parts, many of which are not really designed to contend with them. The particular 3D printer he is using (hypercube) appears to have thicker rods than usual (for more stiffness) and is very open so the sawdust won't collect. but it will float all over the room (a dust management system is needed).

Acrylic and Aluminum require even more stiffness (than plywood).

More suitable for 3D machines are the diode laser modules. These are good for engraving and cutting of certain materials. The smoke generated needs to be controlled, and the possible reflections of the laser are an eye hazard that needs to be addressed.

If you want to have a DIY machine that is good for a number of different tasks including 3D printing, spindle engraving and cutting, laser engraving and cutting, plus more take a look at the https://www.v1engineering.com/specifications/ . I have no direct experience with this machine but am collecting parts for it, I plan to use it as a small CNC router. It can be built whatever size you want, but the smaller it is the stiffer it will be.

I just did a minor overhaul of my Lulzbot Mini with the modular heated bed upgrade. This makes it easy to remove the printbed (PEI on glass) as the heater is bonded to a metal sheet that spreads the heat and conducts it to the glass but allows the glass to be easily removed when needed. At the same time I worked on the Z probe intermittency issue and cycled some connections there. So far the Z probe has worked 100% since, but we'll have to do more testing to see if it is actually improved.

My other 3D printer, a Prusa i3 mk3 has been excellent, that is a great machine. Very consistent and never a problem with the inductive Z probe. I particularly like the flexible printbed that is held magnetically, just tip it off and flex it to remove parts, we never have to scrape that, and it has PEI on both sides so we get two surfaces for the price of one.

Recently I tested the heat-set threaded brass inserts, these are a really nice way to add real machine threads to your 3D printed part. They melt right in with a special soldering pencil tip (or even a standard one can work) and are designed with knurls to really grab the plastic.

Monoprice Select for small stuff, 120mm, about $220.

Prusa i3 mk3 is the most featured for 8" cubed, 200mm. Kit $750. The i3 mk2 is cheaper and a good printer but lacks some really advanced features available on the mk3, the class leader at the moment.

Creality (CR-10S etc) has some fairly low cost big volume printer models. Fairly basic but seem to work. About $500 and up depending on the size, 300x300x400 to 500x500x500 models. Some older models lower in cost lacking some features.

I don't have any of these, but I have looked at a lot of reviews.
The monoprice MP maker pro is supposed to be good as well.

Also what do you guys think about the dual filament printers? Run multiple colors or materials.

Dual filament can be useful, is a bit more advanced and can be troublesome. They cost more and the second printhead reduces the print volume.

Some of them are single print heads.

There are different type of people, the ones that get a computer/games, the ones that get a 3d printer and jump for joy, the ones that get an Arduino/Raspberry Pi, and the ones that get a welder/pipe bender. I could think of a few things to print on that 3d printer, same with a welder. Could make money with either!

3D printers are fantastic tools. Best if you have an eye for design, minute detail and CAD. Designing for 3D printing requires understanding how the process interacts with the design and materials.

Single printhead multicolor printers are not without their own problems. Best to start simple and build the skills first. Lots to learn.

You can make money with them, most people don't succeed at that. It's a tool. It doesn't make money on it's own.

Yeah for me its for personal nick nacks and to use for prototyping for EE work.
