Visiting the old steel plant museum in Pittsburgh changed my view on our sand molds

I went to the Rivers of Steel museum last weekend and saw their original pattern storage. They kept wood patterns for over 50 years, oiling them every year. We toss our 3D printed patterns after a few runs. Seeing those perfect old castings made me think we lose something by not keeping good patterns around. Do any shops still archive their best patterns for future jobs?

Exactly, @jaden69. Digital is just a power outage from gone.

Wondering if it's worth the space and cost though. Those wood patterns needed constant care and took up a whole building. My shop can barely store extra conduit. Isn't the whole point of 3D printing that you can just make a new file when you need it? What are you really losing besides some old wood?

Totally get the space issue, but it feels like we're losing the backup plan. Digital files can corrupt, software updates break old formats, and cloud services shut down. My dad's old shop had paper blueprints in a fireproof cabinet, and they saved the business after a computer crash. Now everything's on a server that needs power and internet. Sometimes the physical thing is the only copy that lasts.
