Filament test and printer capabilities.

Post by _kaktus_ » Mon Jun 11, 2018 10:23 pm

:mrgreen:

I expect that very often I will print some small items.
So it's worth getting to know the properties of the material and the capabilities of the printer itself.
Of course, we are talking about the M201 model. :D

Recently I have prepared a model of an element of a bookbinding knife, which often breaks down.
With a lot of curiosity I decided to check how such an object is going to be made in practice.

I could write a story about the creation of this object because it has its own history. But this is not the place for such stories. ;)

The item was printed in two colors of the same material from one supplier (unless I don't know about something).
Printer parameters:
  • head temperature (hot end) 250°C
  • working table temperature (heat bed) 95°C
  • Layer height 0.2mm
  • 100% printer speed
  • diameter of the nozzle gap 0,4mm
You can clearly see that the set temperature was too high for the blue filament.
As a curiosity I would like to say that the cohesion of these two materials is weak.
When I plugged the blade into the slot, the blue part broke away from the rest.

Already somewhere in the forum I told you that despite the same type of material and identical supplier the filament will have different properties for each color.
That is exactly what I saw here.

The pictures show that the bolt was also designed. This is a metric M6 thread, so it's small enough.

I was very curious how its performance would come out in reality.
Well, there was ... that's what I can say about it. :lol:

I expect that if I used a nozzle with a smaller hole and used a layer of 0.1mm the thread would come out better.
On the forum I help to use the rod, I don't give fish.

From the last moment.
;)

I was wondering about the reason for such significant differences in the appearance of the material of various colors.

Looking at the degree of melting of the blue part of the model, only one solution comes to mind. :geek:

This filament is not of the ABS type, as described by the seller ... :!:

Can anyone using a PLA filament do a test with acetone :?:
This is probably the only way to efficiently distinguish the type of filament.

Unfortunately, I do not have a PLA filament. At least I do not have it consciously.
And it needs confirmation of how PLA will behave in contact with acetone. ;)

Another test to differentiate between different types of material would be to try to print at a lower temperature, e.g. 200°C. And observe the behavior of material and printer.
However ...
Testing with acetone seems to be easier and faster to complete.

I do did a rough experiment this week, soak ABS and PLA with acetone.
Because I have a limit amount of acetone liquid, so I folded the filament sample. But they still looked quite different in shape after several hours of soaking.
Take a look at the pictures below.

After 8 hours of soaking, ABS blue looks like:

PLA yellow:
The liquid becomes yellow(not that clear in the photo though), I think is the pigment got off.
But the shape/form wasn't changed a lot, compared with ABS.

And the final result:
All filament was soaking over 8 hours BTW.

Just out of curiosity.
Hope that will help. :D

Hello Gingko.

This test is great. Thank you. :D

It is clear that the PLA filament is almost indifferent to acetone. Compared to ABS, of course.

Hi.
:mrgreen:

I can count that printout as a success :D

Nozzle diameter 0.3mm, layer 0.2mm.
Unfortunately, the nozzle of 0.2mm diameter turned out to be too small for this printer - or the filament I have.
