Have a TAZ 4 with E3d V6 hot end.
Rails and linear bearings have been replaced recently (makes a significant difference I believe)
Printing PLA with the 0.4mm nozzle (Have a 0.25 but haven’t tried it yet)
I am printing a series of injection molds that will produce tubes of polymer that have outer diameters of 2-4.3mm and a wall thickness of 0.3-0.45mm. The smallest to date has been 1.54mm inner diameter and 2.68mm outer diameter printed at a layer height of 0.1mm
The prints are reasonable but I sense that I am approaching the limits of resolution.
Just wondering what is the thinnest layer height that anyone has used?
If anyone has some suggestions as to how fine printing can be improved I would love to hear them.
In test prints with my stock TAZ 5, I was going down to 0,05mm. Print was looking realy great, it’s nearly impossible to see the layers even on 60° angles.
But it took ages to get only 5mm height on aprox. 20x20mm base. So I canceled the print, it’s nothing thats useful for my print times any more But if I have some free print time one day, I will try a small 0,01mm object
Here is a .08 layer print using a .25 nozzle I just finished. I am very happy with the results!
The total height is 1", diameter is 19/32". The print was 317 layers printed in just over 1 hour.
Ive actually started to do 150% layer height and 65% width (which in S3D makes the layer wider, which is wierd) its almost a perfect extrusion to width ratio… perfect first layer… im sure it varies by slicer etc
