Alignment on the Form 4, "optimal" angles?

Hello, how would you basically position this body? I am not yet satisfied with the printing result. Either I have holes in the surface, perhaps angles of inclination that are too shallow, or I have stripes, or even steps in the body, angles of inclination that are too steep. Before I spend thousands of euros on tough2000 and the results are not satisfactory, I’ll ask in the forum in the hope that someone can give me some useful advice. It is a Form 4 and Tough 2000 resin.

The body is of course positioned in the preform without the components.


Would recommend rotating it around 45 degrees

Hi Charger 01,

this is Jakob of the EMEA services team.
I agree with Jared, an angle of 45° might be needed for this model.
Searching for a “similar enough” model, I found a Puma GTB. I recorded myself orienting and supporting this model while doing commentary on why I am doing certain things.
You can access the recording following this link.

If you’d like more specific advice on your exact model, we’d be happy to take a look, just get in touch with us in the services team, we’re always happy to help with prints before you start them, not just afterwards.

Kind regards,
Jakob

Hello Jakob, thank you very much for your detailed video, it was really extremely helpful! I would never have turned the model like that! I remember that you gave me great support at the beginning of my Form3 time! I’m going to try it out with my ASA right away. Perhaps you can also tell me something about the somewhat unsightly surface, especially with Tough2000 and 50 microns, the surface is not completely smooth! I’m attaching some pictures. The holes here are really extreme! Does this, or could this, have something to do with angles that are too flat? I’m actually from Germany, but so that everyone can benefit from it we can stick to English, I’ll just use Google Translate. Your video about the angles of the model in the build space was incredibly helpful! I couldn’t tell from the video how big you had chosen your original contact points to be?

I have several models for which I would be grateful for any help so that the results are optimal and the rework is kept to a minimum. If I make a general request for support, I won’t be able to get through to you! But you were always the biggest help to me back then! There’s probably no way to contact you directly, is there? Thank you again for your great help!

You can also see extreme striping on the roof of the Fiat. I mainly print Tough2000 at a resolution of 50 microns, 25 microns is not possible with this resin. A guy here in the forum gave me the tip to reduce the mixer arm speed in the print settings because of possible bubble formation that could occur at high mixing speeds. So I created an individual print profile for the Tough2000 layer thickness of 50 microns and reduced the mixer arm speed from 600 to 200 mm/s, do you think that is necessary and that the bubble formation could really be a problem?

Problems with holes and streaks in the surface!
