What you can do:
Use Preview quality reconstruction but with changes to the settings:
Mesh calculations - Use sparse point cloud FALSE and Maximal vertices count 500,000 or 1,000,000
That will give you a quite decent result within a rather short time.
It may actually be good enough for your needs. You’ll have to try.
I use it for turntable scans most of the time and it does save me a lot of time. The result will not have all the very fine details but the texture more than makes up for that.
