The frame is a bit like the structure of the printer, there are a lot of them, varying in design and materials, technology of functioning and more.
At first glance, even without being mechanical experts, you realize that printers differ from each other in terms of construction technology. In this article we review all the main building technologies on the market today.
But even if we just talk about FDM printers (Fused Deposition Modeling, the most common desktop printers) we can see some differences also within this group.
Frame: Kind of
The printers in this category can still be divided into 3 subcategories: in fact, based on the design we can have: printers like Prusa, Core Xy printers and Delta printers.
The main difference is how they move the plate and the nozzle, and each one has pros and cons compared to another.
Prusa Printers: These are simpler, as installation as usage. Simple moving axes in a easy way. Recomended for Noob!
CoreXY printers: Are a bit more difficult, having belt moving in strange way. Having bed moving just on z axes can print little more faster then Prusa model.
Most of corexy are prebuilt, even you can find some one in KIT.
Delta Printers: Are absolutly faster printer, but hardest t understand. These having some advantage using 32-bit mainboard.
Another difference between the frames of the various printers that immediately catches the eye is the construction material. We can find printers made of acrylic, wood, aluminium and even printers printed in 3D!
Obviously, the more rigid the material that will make up the frame of the printer, the better the printing will be.
So for the same price you should always prefer an aluminium frame rather than an acrylic one.
N.B.: In principle it is always good to stiffen the frame, with new joints, of whatever material is made, even of steel.
You can find aluminium profiles online: on AMAZON
