TOPIC:

After my day of work, I went for another scanner session...

This time I used high accuracy in the capture (it was in standard accuracy last time). I started by capturing the body. For this I used the black support (black means the scanner will not capture it), as the body itself should have enough features to allow proper tracking easily....


I use some packages as support for the scanner or the turn table to take the capture at different height and orientations. I also put the body in different position directly on the turn table to add additional captures...

Then I merged all the point clouds based on the features, and about 5 minutes later, I had a very nice body...


I redid the same for the helmet, but with the white support with slightly better results on the scan itself than for my previous capture...


I think I can still improve the support, so the bottom of the helmet is even better... But that's for next time...
 

Gone for some test prints...


I'll put a comparison between the original parts and the printed parts later on after the printed/cleaned part are fully dry and cured...

They already look nice

yes, plenty good enough already!
I'm still asking myself if there is way to get better definition. I'll tweek the edition, as I believe there is a bit too much of smoothing in the automated editing... In short there is room for improvement... Even though it's probably good enough, considering that most of the reproduction I saw relying on a silicon mould are not really giving much sharp edges... But clearly, this is on the sharp edges that the scanned file could be improved...

Try a black line with a pen between fingers and points of pens for the face.  My colleagues uses round stickers (gommettes) to scan 1/1 cars. With a flat spray on some zones.

I don't think this is the problem. I think it is smoothing in the post processing which is the issue...
NB : white primer was applied on both body and head before starting. And all edges avec the same loss of sharpness...

these are pretty good results and as you said, there is post processing you can tweak. I would guess the software is trying to reduce as many points in the model as possible.

What is the largest object that you think you can scan? I am guessing a car body is out of the question (even is painted properly). But scanning parts of a body or chassis to make new parts fit might be worth a try.

Johann, for bigger objects, I have no clue yet... I'll have to try. That said, the head dimensions are below what the specs tell for the minimum size of a scanned object... But just refering to the specs, for a car, it's probably a range or a miraco scanner which is required...

But lot of condition may apply to get a proper scan :

• sunlight is not good for scanning : inside is better
• reflecting, clear, brilliant paint are not good either
• flat surface (in terms of light reflection is better)
• uniform surface are difficult to scan, and markers may be required
• ... (anything I did not identify yet)

I'm really puzzled by resin printing some times : I have around 1/8 print fails with standrad resin. 

The kind of fails I can't explain : bed level is good because unchanged, next print with the same file is working. At this stage, I believe my bed might not be as clean as it should, but generally, ending a print, removing printed parts from the bed and start next print would work. 

Funnily, most of the times, the first print of a serie is always the one failing (the one after I cleaned the bed since last serie). Knowing this, I generally check my prints few minutes after the beginning of a print, to avoid loosing too much time and material... Let's see what happens for the test prints I launched today...

The test print to check the last scans was done successfully...

I rescan the head of the Super Wheelie differently, with a slightly better result again...


The Big Bear driver figure scan is actually much better than what I thought it would be... I still wish to find another one in parts so it is easier to scan...


Last the Hunter/Galaxy driver is in two parts, like the Super Wheelie : body and head... And the same process I used for the Super Wheelie head was used.


I'm questioning myself about putting those on shapeways or cults3D to make them easily accessible...
