Newb warning: Most of my experience is CAD, solidworks, adobe (but not fusion). I have had classes in zbrush but never owned it. Most of my software of any value is at work. My home stuff (used for my stuff) is free or old. I am a NEWB in 3d sculpting and in 3d printing. My CAD machines weighed in the tons. My 3d printer can be lifted with one hand, I feel totally lost. But here is my experience so far:
The scanning was done with a Revopoint Miraco, hand held scanner that I borrowed from my aunt. The software needed for its use is Revoscan5. Scanning is a physical skill but limited by the software and the scanner. It is worthy of not only its own thread but its own website for training. Please add links to your favorite training sites. I have a renewing one year subscription to Stan Winston school of Character Arts which costs me less than one tire on my car.
The revopoint miraco has some very good mesh cleaning tools built in and is a VERY important first step if using a scanned image for 3d software sculpting or printing. For camera only scanners, these tools would be found in the computer software revoscan5 and yes, for those paying close attention, those are 2 different softwares. One is IN the miraco, it is a hand held stand alone computer. My aunt's new toy.
It creates a mesh image. Mesh is the net of dots/location points picked out by the scanner to make the rough outline of the object. STL is a mesh type file. This is NOT the same thing as a 3d modeling file. It is not a vector 2d drawing nor a set of 3d geometric parts like Fusion or CAD.
I could not find a program to simply apply the lower flat surface so my scan was empty back. Jintosh repaired a lot of the mesh issues and put the flat back on it. From there I used all free software: Blender, Chitubox, meshmixer, Bambu and finally Creality. The only one I would say to avoid is creality as there are far too many stories of trojan software that have been confirmed even though I am using a creality printer.
Most of the digital sculpting was done in Blender but you MUST run on very high resolution when sculpting or it will corrupt the file. BIG WARNING: Blender has a serious tendency to use the tools at a mirror effect coming through the opposite side..... when sculpting thin parts. This will destroy the entire file. Always turn the tool settings to "faces only". Or just use zbrush instead, if you have access to it.
For some parts I liked the adobe meshmixer sculpt tools better. Making the back bars from the tubing tool was super easy in meshmixer but a total nightmare in blender. However, meshmixer has a huge fault, actually about 3. First, the tool you are using reaches across the entire screen, meaning it is NOT just sculpting the part you are focused on but will reach through to all pieces in a striaght line and do the same thing to them. It is common to find huge blowouts on parts you did not touch. Second, the tools have a bad tendency to ramp up so you have little option but to continuously let go and tool, let go and tool, in sequence. Third, and this one is phenomenally poor programming, the sculpt tools are all still active while you are using the xyz rotational tool (the click, hold, and turn). So, you are spinning the sculpt but are using the little xyz shape to rotate it and part of the sculpt comes up behind the xyz rotation tool and it begins to sculpt that spot with whatever tool is currently selected. So, you get it spun and you release the click and go back to sculpting and there is random friendly fire damage everywhere. I did not get used to just using the scroll wheel as the tools were different than blender. I finally learned to always change to the selection tool before using the rotate tool and then rechoosing my sculpt tool.
I used bambu, revoscan 5 and chitubox to fix holes, smooth or lower file size and to create parts slices because blender's cutting tool was usually destructive to the mesh.
After sculpting to a level I was satisfied with in blender, then adding the pipes (belt loops) in meshmixer, I found that only meshmixers "join" really meshed the parts rather than just assigning a join glue bond. I also further found that it was easier to clear away the mess in meshmixer at the point I smashed the back bars into the clay front sculpt. After this was cleaned and the two parts looked truly joined, could I go back to blender to use its superior clay tools.
One more lap through the mesh softwares to close unseen holes, simply oversculpted mesh (crystal crunchies/clusters) and to delete lost fragments and then off to the printer.
I printed the files I last uploaded to the threads.
New printer, never used one but I could already sense the impending implosion as I began watching youtube videos. As is the norm with youtube, most of the videos are stolen content. People who need to up their content count, so they go around watching other people's videos and then just play act doing the same process but not really understanding what they are doing. Using phrases that don't really mean anything, spewing bad advice and wrong advice.
By the time I had my 5th restart, I was furious about the level of lack. Many, many videos joke about how everyone has to "go through the pain of being a newb". But in all fairness, that would only be because of all the lies and appropriation of other people's work that leads to this "guess til you get it right", mentality.
But having decades of engineering and software background, I could sense where the instructional gap was. Somehow the use and procedures for what people were calling "table leveling" or "zeroing the z" were really people simply not having a clue what they were talking about. It isn't their fault as my installation software skipped all of this information as well as did the written instructions.
The moral to this story is, TRAMMING THE BED and then using a mesh leveling touch scan if available. This is for filament printing, of course. Tramming is the use of the adjustment wheels on the print bed to get all points of the print bed in the same plane as the travel of the print head when the print head is NOT changing height but just moving front to back and side to side. Some printers do this for you. After this process, you can use the touch bed scanner to map if the bed is warped. My printer calls this button "leveling", so everyone who sees it thinks they don't need to tram the bed but you need to do both.
This guy was the only person speaking real logic and not just repeating what he stole from some other persons videos:
I had seen this video in the morning and talked with my gaming buddy later and he confirmed it. First step, clean the bed with soapy water if you can take it off. Then put it back and clean it with alcohol and don't touch it with your fingers again. And here is the protip: light layer of Elmer's purple color changing glue stick and let it dry but then Tramming and then meshleveling touch scanner and then print.
So, my print started before my last convo with a true pro, so no alcohol and no gluestick but I did tram the bed to plane with the print head and did follow the guy's instructions for zeroing the z height. Buuut, I also followed a video specific to my printer to see the control settings on doing the z bit.
Things that even the manufacturer left out: do not tram, nor zero the z before checking which corner is the highest on the bed. Simply following instructions will crash the print head into the table if the corner you started on was the lowest. Do not just start pushing it around when just a hair thickness above the surface, move slowly and if you contact the bed, lower each wheel and start again.
Also remember that when adjusting height, go slow because all adjustments whether physical or digital seem to affect slowly so you may over adjust.
Only after tramming the table height adjusters to match the path of the print head, could I get the filament to stick....AT ALL. It wasn't temperature, not speed, nor a clean surface. I was too high off the table while printing. Before doing the full tram adjustments process, all I got was moving spaghetti. Afterward, I got solid adhesion and a perfect print.
I chose super high quality at .12 in the creality slicer prep program just before loading into the printer. It creates a full gcode file (the directions for printing in x y z directions like CAD machining). I chose slower first level speeds, a wider and lower first layer and used brim foundation wings to get a solid stick to the table. Now I know to use the gluestick but did not on this run. I turned on supports and let it run.
So before I even ran out of my free sample set of filament on my first ever 3d print (ya after 5 spaghetti starts, but used stop to not get past layer one) I got this:
Removed from plate and remove support material:
Clean up with minor scraping and now ready for paint.
The two curves we have been calling the norse horse eyes are very fragile so avoid scraping them when cleaning.
Because of choosing the .12 super quality setting, I have no sign of shelving or layers at all. It is very smooth. I did turn on ironing for the last layer but beware that ironing is NOT recommended as it can collide the head on taller objects and knock them off the print bed. I didn't know when I clicked print.
It is so awesome smooth though:
So now we talk paint. Give me the low down on cleaning and prepping these pla parts. I am assuming a dull silver or pewter is our goal color. My best description is "pot metal". In the real world that is a zinc and sometimes aluminum poor material fir things like screen door handles and knobs.
