MrObsessive Posted June 7, 2022 Share Posted June 7, 2022 (edited) Months ago, I printed out a file I got of a 1967 Maserati Ghibli coupe. One of my favorite European cars from the '60's and the first effort wasn't too bad considering. Since that time, I figured out a way in Blender how to separate body parts from one another if the file was originally created that way (there's another more tedious why if it's not), and wanted to do another Maserati. This time with opening doors and hood. Since I'm still using my small Phrozen Sonic Mini 4K, I needed to once again split the body in half with 3D Builder, and run the two halves at different times. The rear clip of the car I did first, but my better sense was telling me to put some sort of bracing between the roof and the rocker. I've had an issue in the past when the slicer detects too many "open area", it will not form the supports, despite them being in the preview screen before the model is sliced. Here are pics of how the rear half turned out............ Very nice how it came out, and no issues with missing or halfway formed supports despite part of the doors being edited out. I noticed that the trunk would not separate when I was doing the original editing.....that's probably just as well as I can 'bout guarantee with that open area, there would have been an issue. The next day, I moved on to the front half of the car, and here's where things got interesting. I had edited out the hood and saved that as a separate object, but my sense was telling me to try and put some kind of bracing(s) across the hood so the slicer can "see" what needs a support there, and not have an issue with either missing, or halfway done supports. Well................here's the results of that. 🤯 Obviously, this front clip is trashed as there's no fixing it and I wasn't even going to attempt to try. I tried it again, but this time I left the hood in place, and made extra bracing between the edited out doors, roof and rockers. Much, much better this time and I'm stand by my thought that the open doors have some type of effect on how the supports will form, or lack thereof. When I first printed the front half with nothing edited out back in March, I had no issue whatsoever and I'm glad I added the extra bracing as a failed print certainly would have happened. I can see though that the supports stopped forming about where the top of the side bracing ended. I don't know if that's an issue with Chitubox's software or with Phrozen, but this has happened before with opening panels. I got the two halves joined together, and I sprayed a very light light coat of primer over the join areas to cover the putty I used. A MUCH, MUCH nicer result this time around! I can always cut the hood out at a later time as there's a scored line in the underside which makes this easier to do. Since I have the hood separated as its own object, I can always print that out if need be if the cutout hood gets damaged in some way. One thing I noticed is the difference in scale of the newer printed body. IIRC, the first body I ran straight from the vendor with no changes in scale. The latest body, I scaled the file out in the slicer as I have specs of the 1:1, and wanted this to be true 1/25. Notice the difference in size........... I can always add trim for around the windows and roofline later on. Of course, I'll have to build door jambs for the body and doors, as well as make my own hinges. At some point, I'd cut out the trunk also. I'd brace the inside first however as the hinge retainers would need more real estate to rest on. As the months have wore on since I got the printer, there's always something new I'm finding out. I hope in the not too distant future to get a second bigger and newer printer (same brand), and I'll be curious to find out if I'm still having the same issues with missing supports whenever there's any open areas edited out.
