3D resin printing stepping, any ideas please?

[MJI]

Mars 2 Pro

 

I know it is possible to get a smooth finish with resin but on some surfaces I am getting a corrugated finish.

 

Using Chitubox with out of box settings.

 

I KNOW I am doing something wrong, but do not know what it is.

 

I have dumped them here, any ideas please?

Can you give us some more information?

 

What are you printing and how have you oriented it with regards to the build platform? Some photos would help.

[MJI]

OK I have downloaded some LMS hoppers from IronMink on thingiverse and thrown them into Chitubox

 

 

I will add a couple more supports

 

I am now going to post from phone so will be a few minutes

[MJI]

Would not load so used whatapp web

 

The sloping bit is fine but the top of the side is furrowed, as are solebars and W irons

Of course, I posted a bit quick originally.

 

I will be sanding these smooth but I want to design a couple of wagons not available myself and don't want to spend ages tidying them up.

These!

Try rotating the items on the Z axis so they are not parallel to the build plate (30 degrees?). 0.05mm for a layer thickness might be improved by going to 0.02mm although it will increase print times.

Thanks MIke, would I need to change the exposure though?

[MikeTrice]

Yes. Try halving it. Most user groups have suggested exposure settings for various machines/resins so it might be worth doing some research. (Try: https://www.facebook.com/groups/elegoomars/)

I have joined a few groups and reprinted at a rather weird angle, a few holes from the supports but quite a bit better.

 

Hope to complete one apart from brakes this weekend.
