don’t have a 3d printer? if you had it what would you do with it?

3d printer? how would you use it?

Very often, talking to people who see that I have built a 3d printer, I get asked this question “what can you do with it?”.

Doing a simple search on the web we see that there are many sites that provide for free hundreds of drawings of objects reproducible with a 3d printer. The site, I think the richest of these projects, is in my opinion Thingiverse, a community open to all those who want to try their hand at designing and drawing aimed at 3d printing, both experienced cad users and newbies on the subject. On the site you will find everything, from cellphone stands, to the famous and useful USB cable reels, earphone holders, raspberry or arduino cases, covers for most of the cellphones on the market and obviously supports for the now widespread intelligent assistants.alexa Continue reading don’t have a 3d printer? if you had it what would you do with it?

hotend, what it is and how it works

Hotend, how it’s done and how it works

The hotend is one of the most important components of FDM 3D printers as it deals with the fusion and subsequent deposition of the layers of our piece to be printed. Even if, trivializing, it could be said that its task is “only” to dissolve the filament, reality teaches us that to perform this simple step well, a hotend must have not indifferent qualitative characteristics of components and assembly to guarantee a smooth running smoothly. The parts that make up a hotend are not many and I will group them into 3 sections which we will then analyze individually.


Let’s get to know the importance of the 3 areas better, starting from the entry for the filament with pneumatic connection. It is certainly the least critical part of the hotend, it only has to ensure the entry of the filament into the actual body of the hotend. The pneumatic connection houses the PTFE tube where the filament flows. The pneumatic connection is screwed to the hotend body and ensures the absence of play in the case of an indirect bowden extruder

problems with 3d prints

Let’s learn to analyze the problems of 3d prints

You do not expect to find in this article the solution to all the problems of 3D printing, but more a suggestion for the analysis of the results to allow you to improve the quality of the final result.
I took photos of 3D printed pieces of an acquaintance of mine as an example, obtained with unsatisfactory quality, to analyze the defects and then try to eliminate them by trying to identify the causes.
The more experienced will surely find my considerations useless, but to some neophytes, like me, maybe they will suggest where to act to improve the quality of 3D prints.

It being understood that a good printer, a good hotend and good filaments certainly make the difference, let’s see the first photo, a classic …… the detachment from the print bed.
In the photo below we see the inverted piece with the angle that tends to go down, actually to go up 🙂


Let’s see what happened.
