[QUOTE="Affinity, post: 153684, member: 1246"] Its true it is a matter of scale and procedure, if your procedure is tight, the work should flow perfectly. Im only speaking of experience in other larger or even mid-sized labs that really dont respect the model and are dare I say sloppy. Im not a model snob, I dont need a beautifully trimmed and polished model to work on as long as its clean and accurate. This is how I keep it lean.. keeping stone to a minimum so that I have to trim nothing, flattening bases on solid models when they are poured, so that Im not having to model trim them to keep them flat as I do contacts. Plasterless articulators are also amazingly fast for me, I dont use them for everything but for certain cases they work great, like nightguards. Slurry water works the way its supposed to, it sets gypsum faster, but I wait over 24hrs generally to start trimming dies until stone is completely dry so I dont need a fast set on my opposings. Now that everyone is digital they are trying to shortcut one or both of maybe 2 analog steps needed to make a crown anymore. (Model/Glaze) Just because digital is faster doesnt mean the rest of the process should be too. To me having a lean model room means accuracy first.. I think this sets cases up for consistent success. Fat trimmed on the back end. [/QUOTE]
