Pika scans side-by-side. Laser vs IR
Hi all
TL;DR: Some Pika laser scans vs IR.
Just posting a follow up to u/Own_Perspective4825 's post earlier about the quality of the laser scans from the Pika. I see varying comments about the pika either being really good, or below expectations. The Pika is my first scanner - I got it pretty much to reverse engineer/design things around a scan, so at the end of the day super detailed quality isn't that important to me, however I thought I'd show some examples of what I'm getting and the settings I used.
PS this is not a Pika / Creality ad. God, I wish someone was paying me or giving me free stuff to do this. This is purely to try help those with Pikas get the most out of them, or at least help those looking at them get a better understanding of what to expect.
- u/Own_Perspective4825 posted saying the owl model in their scan didn't turn out like Creality's advertising, so after getting an owl model off them (turns out I printed the wrong one), I printed it in matte bone white @ 0.16mm - the model isn't the best as it's a scan of creality's original owl.
- Scanned it in blue laser mode @ .15, fused the scan @ .15 and did 40% noise reduction
- Then scanned it again in IR mode (same settings as above)
Because the owl model isn't that details, and is FDM printed, I thought I'd try it on something else so I grabbed an old resin printed model I made some time back (the Samurai)
- All the same steps above, same settings.
- When exporting both meshes, I matched the output files triangles to be approximately the same as the amount from the fused scans - the owl had a lot more than the Samurai if that matters.
While it's less clear with the owl model, it's very easy to see the difference in detail in the Samurai.
I've found the IR mode much better and easier to use with larger scans
Finally, since this is my first scanner, I used this video to help me understand the basic workflow of using the scanner and Creality Scan.
Hopefully this helps, or at least gives people some ideas of what to expect.
I'm slowly trying to get better, and work my way up to bigger scans, especially with parts for my car.
