This is theoretically possible. Practically it is possible if the small printer is able to print all necessary materials – from plastic to metals to electronic components.

But the latter is currently not possible in my knowledge. You cannot currently create a computer chip with a 3D printer.

Thus, the construction of a 3D printer would be possible – except for the electronics that must come from outside.

Currently we are still a bit far from the “From Neumann Machine” – its self-reproducing machine – at least in this size and this complex technology.

Define what exactly you want to print with it. The Prusa or Voron is made in principle – when it comes to mechanical recording, electronics recording, etc. Complete with electronics and guides etc. hardly.

So is a definition question. This is also quite demanding because each plastic has certain properties which are advantageous for certain things, but others are more disadvantageous. So your printer must master a variety of materials – just like yourself. It doesn’t use anything if you can, for example, process nylon or IGUS on the printer – but you don’t have the know-how and the pre-requisites and correspondingly only produce “Spagetti” or “Banans”. Similarly, you must take into account the conditions of 3D printing, depending on the method used – probably FDM or SLA. Simply drawing and printing will inevitably lead to a dead end in the case of more complex components or cause a rapid “deviation” during operation.

The plastics a) also have a strong setting behavior under heat, and b) temperature differences also bring about enormous tolerances. They also have to be “absorbed”. Also, but not only, by proper choice of material. What is a possibility, if you can, would the critical parts from PLA be as precise as possible, then take off in molding sand and pour with brass or aluminum. If only then indirectly per 3D pressure is still present, but the material properties are increased at the point over all doubts – if the plastic meets the requirements exactly at the point, then the metal part has no problems – even in continuous operation under temperature. If the heat is collapsing, you have a huge constructive problem…

But it is also a cost question: filament is expensive. Electricity is becoming more and more expensive. Wear parts cost money and are not cheaper. Cost item profiles to measure. But are there after a few days and, if you calculate sober, are ultimately cheaper and more durable than printed constructs – See requirements…

Only the meaningful application makes it interesting and favorable. You can print everything – only if it ultimately makes sense that everything is printed, stands on a gaab other sheet…

A working mate used to energize me for days, so I’m supposed to print a drilling and bending gauge. It was a recurring activity that was rather annoying with fairs. I got too stupid. I told him, okay, I’ll teach you a lesson. I grabbed a plastic sheet, cordless drill, hot air dryer and tear-off material (needle, ruler…) and drilled the plastic, made hot and bent the hot plastic carefully into position on the bending machine. Last 10 min! If I had printed the part on the printer, I wouldn’t have created the CAD in time – drive up with computer, start the program… Let alone export to the slicer and then sliced there and at the end also printed… This, for example, was an impressive example where 3D printing would have been feasible, but absolutely meaningless…! And I actually print quite a lot and with different procedures on different models. But one has to question: does it make sense in the procedure or are there better/more favourable procedures to get a comparable result?

1. Since different printer types are required for the necessary materials.

Two. The accuracy is not sufficient (e.g. for the guide rails).

(3. Not all materials are printable. It would be less relevant here.)

The basic framework may not be the technique

Various parts can of course be printed. But not all, all electronic and electromechanical parts, as well as metal rods, threaded spindles, etc., not.

In individual parts this would have to be possible in theory.

Electronics don’t share….

You have to read the article “Contacting is done via inserted spring contacts”. The ectronic components were then inserted/”set”. But the text in your link is added very bad/unclean and therefore easily misunderstandable.

Actually,
