I have found it really depends on your production.
I have the envisiontec machine. Which I can grow 7-10 pieces Like 3
stone rings or solitaires. The grow plate is roughly 60x40 mm.
The advantage to the envisiontec is it grows all 7-10 rings
simultaneously. Which decreases the production time.
I am about to purchase a solidacape for the more delicate pieces.
Reason being is solidacape takes about 3 times as long but it is a
real wax with fewergrow lines.
Feel free to call me if you have any further questions.
I can send you a sample of the evisiontec “waxes” and let you cast.
