can't wait mmu2s and water-soluble support material for complex 3D printed objects (see post) ... a lot of tricks ... lack of PLA (see post) ...

next print will be assorted color ... with much better result ... stl files will be available soon in 3D printing communities ... and the links will be provided ... by updating this post ... stay tuned ...
As you as you probably read in the previous post 3D Model - Heaven's Stars - Constellations - Milky Way next print will be done with mmu2s and water-soluble support material (for complex 3D printed objects). Although i know this is the propriate method to get the perfect result i couldn't wait for that day. After watching some video ...
I thought of making a new attempt to print the design in two parts using the MeshMixer ... (I must mention for the newbies, like me, in 3D) ... that is a free and perfect software from Autocad. First trial with MeshMixer basic settings for tree supports ... import to PrusaSlicer
Layer Height 0.2 mm
Post Diameter3 mm
Tip Diameter0.5 mm
Base Diameter8 mm
MeshMixer made all the job but printing tree supports in the middle of half sphere of 102 mm (10.2 cm) is a little problematic ... especially when anyone has a design that needs a lot of trees ...
Second trial with MeshMixer basic settings for tree supports ... import to PrusaSlicer ... add shape (to create a base that keeping the trees upright) ... export from Prusa Slicer and import to Mesh Mixer for aligning with the main design and combine the stl files ...
Mk3s made the job perfectly ... but ... the tree supports with 3mm post diameter on design with 3mm tubes ... give a lot of problems during cleaning.
By the second trial almost run out of the Prusament PLA (Azure Blue) and change to Prusament PETG (Clear Transparent) so ... with my small knowledge ...the tests can not be comparable ... νevertheless ... Third trial with customized settings for tree supports in MeshMixer
Layer Height 0.2 mm
Post Diameter1.9 mm
Tip Diameter0.14 mm
Base Diameter2.9 mm
Mk3s with such settings and PETG has some troblew for the tree supports that i think that would not exist with PLA (especially if use smaller layer heights that i avoid for time and material reasons).
Fourth and final trial with customized settings for tree supports in MeshMixer... import to PrusaSlicer ... keep the shape that added in the second trial and add shapes (cylinder 3mm) for each high tree that was created from Mesh Mixer ... export from Prusa Slicer and import to Mesh Mixer for aligning with the main design and combine the stl files ...
Layer Height 0.2 mm
Post Diameter1.9 mm
Tip Diameter0.14 mm
Base Diameter2.9 mm
Mk3s made my thinking reality. The half (north) part printed well ... till the top ...
The PETG category of material maybe is not the right category for the design ... as it gave some small problems ... ... problems that i didn't have when finish the printing of the other half (south) with the remain PLA material.
Pins are coming from a ... 3 mm paper clip. This post made in order to give a proposal ... in similars cases ... that anyone needs thinner tree supports ... not easy to grow on 3D printer plate. Final picture will be uploaded as soon as mk3s finish the base and semicircular arm. This work is licensed under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License.
This posting is my first about the 3D printing technology. It has to do, as mentioned in the title with a 3D Model - Heaven's Stars - Constellations - Milky Way.
P.S. I want to give my best regards to Joseph Prusa and his team for ... mk3s and prusaslicer and also to joan.t (Veteran member at Prusa forum) for ... PLA settings and bobstro (Illustrious member at Prusa forum) for ... support material settings.
