    I want to start using a .25mm nozzel to print small cards with lettering on them. When I print with the .4mm nozzel the setting are 210c to 220c pla at a default speed of 60mm per second. Question is what speed should I use with the .25mm nozzel and should I drop the temps some also?

    Thanks

    What about the bed? Do you have a heated bed? In my experience with Cura 2.0, it doesnt even use my heated bed. It does however an initial print later at about .15mm height - and it works. Keep the temp 210c or 220c and you should be fine.

    I run the bed at 65c for all my pla prints.

    Whenever I go for fine detail I cut my print speed in half then experiment up, I typically don't have to mess with the temps

    speed, layer size, temperature all these things need to change.

    Layer size and speed are close to linear (if you cut one in half the other needs to go down by 50% too).

    0.25 nozzle probably needs about a 0.1 layer height (you need to experiment with various ones) and speed at least half of your 0.4. Temperature will likely go down a bit as well but, do some test prints to find the new sweet spot for whatever roll you are printing from.

    Maybe try adding some brim also for easier removal from heated bed.

    Thanks I thought I may need to drop the speed some but wanted to make sure.

    Thanks again.

    Good luck.
    Your if your temperature settings need a tweak it will be nowhere near as drastic as the speed and layer size.

    Hey let's see a print when you are done to show off that detail. Been thinking playing with more nozzle sizes.

    Thanks Mark.

    I will print the same thing with the .4 and the .25 and post the picture of both.

    Ok here is a side by side picture of a .4mm and a .25mm nozzel[​IMG]
    As you can see the .25 nozzel did a great job of printing the numbers and letters.


    Settings in Simplfy 3D
    Layer Hight .1
    Top Layers 4
    Bottom Layers 4
    Shells 2
    1st Layer Hight 100%
    1st Layer width 100%
    Default speed 30mm/s
    outline under speed 70%
    Solid Infill under speed 100%
    x/y Axis movement speed 80mm/s
    Z Axis 16.7mm/s
    Infill 30%

    Wow.. Huge difference on the letter and number details. Very nice option to remember. Thanks for the share.

    Since 3D printing is all about compromises, what was the time comparison between the 0.4 mm and 0.25 mm nozzle prints?

    .25 was 03:37:31
    .4 was 02:48:20

    So just about an hour which is not bad. I forgot to include the infill was at 30%(I am going to add that into the setting in the other post).

    That's not bad really. If detail is my goal for a part, then time isn't a big deal. That's a little more than half again the initial time, but like Waldo says it's all about compromise.

    @danzca6 remember that the particular model is rather small and the difference is about 30%, so as the model grows the time will too.

    Oh no doubt. I had tried printing a medal for a friend for a run he did but the details were lost with the .4 nozzle. So this would have been great. Now doing an 8 inch tall print off something would take a lot of time since not only are you doing .1 mm layers but also allowing the print way down for the smaller nozzle.
