I have a big print (for me) I want to do, and I decided to use a 0.6mm nozzle to increase the speed and make the print stronger.<\/p>\n\n\n\n

The print is a Lithophane\u00a0lamp model of the Moon<\/a> on Thingiverse by humphrey_b52<\/a>. It is going to take around 29 hours to print.<\/p>\n\n\n\n

I changed the original brass 0.4mm nozzle on my Prusa Mini+ to a stainless steel 0.6mm nozzle. Before I set the Moon print off, I wanted to test the eSun eMarble PLA. What better way to try than a benchy?<\/p>\n\n\n\n

The initial print came loose after around 15 minutes. I had cleaned the bed before printing, so I increased the temperature to 65C. The model was printed without any further adhesion issues.<\/p>\n\n\n\n

Apart from stringing, a minor issue, there was a problem with the stern verticle hole.<\/p>\n\n\n\n

A hole appeared on one side.<\/figcaption><\/figure>\n\n\n\n

I can only assume this was because the wall was single in this part of the model. I expect printing a larger version would solve this issue.<\/p>\n\n\n\n

\"The<\/figure>\n\n\n\n

I was happy with the print with the new nozzle size. The difference is hardly noticeable compared to the previous version of the benchy, which was at a finer layer thickness.<\/p>\n\n\n\n

Bridging was similar on the forward cabin window.<\/p>\n\n\n\n

You can see slight shrinkage in the first part of the model. This is because I compared it to an old model of the benchy printed on a different printer.<\/p>\n\n\n\n

It is noticeable compared to the 0.4mm version at 0.15 layer height.<\/p>\n\n\n\n

\"Comparison<\/figure>\n\n\n\n

It isn’t easy to see the difference between the three prints without looking closely.<\/p>\n\n\n\n

The print time was approximately 10% quicker with the 0.6mm nozzle. The theory is the larger nozzle also increases the strength of the prints. I will have to try my 0.8mm nozzle next.<\/p>\n","protected":false},"excerpt":{"rendered":"
