How 3D Print Projects are Born
Three dimensional printing is NOT just about the printing. The printing is a machine process. Machine set-up is a complex setting of variables that constantly change for an equally complex set of reasons.
Not getting into machine settings here, as every process, print, and printer is different. Starting points are good but anyone who has a die-hard favorite setting that ALWAYS works Is probably just overwhelmed by the variables and perhaps fears experimenting. It's easy to "mess up" what seems to always work... Ha!
MayDay, only becaue it is May1, 2022. No distress, yet.
CETUS2 (production) is coming along very slowly. I am so blessed in a non-religious way (ok - lucky) to have a pre-production version with which I can play. I call it play because I have no instructions. I just learn by playing. It works for me.
I am able to create very decent prints. I have had prior experience with single nozzle dual and triple filament printers. So I know what to expect.
First PETG print on my Cetus2
Using my trusty "dented.stl" model file. I decided it was about time to experiment with other filament types. I have some PETG transparent red and blue that I loaded on the Cetus2 feed system. For this print I ran Nozzle3 (the 50/50 mix) at 240C and a layer height of 0.25mm. Speed was set to "normal".
The print looks quite good with very even all around deep purple color blending and no evidence of nozzle "color position stripes".
I had to create a new material file for the PETG and manually configure it into every master file (4) that I have created. Then from there, copy once into the Wand material files out of a created .TSK file that was configured using the PETG material defininition.
Material configuration is still a poory implimented clumsy function within UPStudio3. It should be a one time one place configuration process connected to any routine (including WAND) that needs the data, Making any later adjustment means going back to every location it is stored and doing a separate edit. Very poor practice. I hope this is on the improvements list.
I have also noticed that UPStudio3 no longer appears on the the Tiertime site as available software to replace the standard UP Studio used on all other printers. I am assuming UPStudio3 is being especially configured for CETUS2 use only.
However, I can find other than CETUS2 printers in UPS3 after adding a .stl file and checking the printer listing again.
This is the first 2 color 3D print I produced using the new UPStudio3 (UPS3) version 3.2.5 using the “Paint” command.
The original .STL file is a once piece, single object file I named “dented”. Other examples of this print can be found in the blog. The colored areas here are selected with UPS3 with the “Paint” command selected within the floating drop down menu.
The cursor is used to select flat enclosed areas in the drawing within selected angle ranges. I am not yet fully aware of everything this command will permit in selection as this is my first attempt and have not seen nor received instructions.
I chose to use the purge tower as I wanted best results with this first print. I do believe the “shadow” (no tower) option will also work. I will try a print using that option later.
I posted in the kickstarter forum, there are several more print options in this new 3.2.5 release. The print extruder Entity ID can now be selected in the “Special” command tab assigning print function to specific nozzles. That was not used for this print.
