Kit Type: 3D Printing & Post-Processing
This Kit contains all the products necessary to print models and post-process for the fabrication of In-House Aligners.
This is a great option for reorders of IPA. When purchased in gallon containers, additional hazmat shipping charges apply. Once you have 4 gallon-sized containers, it is better to purchase this item because in smaller containers, hazmat shipping is not added. Just refill your gallon containers for reduced storage.
