Why don't they just use solidified wood pulp, and remove the paper gluing step? Seems inefficient to me.

- replicatorblog 18y agoyters, is there a technology like that used in industry now? If so do you have a link?
- yters 18y agoNot sure. I googled "pulp molding" and saw a number of pages on things like egg carton molding machines. But, solidifying a whole block seems tougher.
- replicatorblog 18y agoYeah, typically the issue with molded paper pulp is keeping a uniform wall thickness otherwise the moisture is trapped and you have a crusty object with a slushy inside.
- yters 18y agoCould they build it in layers? Or is the best way to do that to just do gluing, so it's back to the original idea?
- abstractbill 18y agoRight, but you can't pop down to the local store and buy wood pulp (can you?). This does have the advantage of using something you can buy practically anywhere.
- yters 18y agoHmm, in that case, the machine should generate solidified wood pulp from any paper waste. Then your source of material is much larger and cheaper - i.e. cast off cardboard boxes from the local supermarket, irregular shapes and sizes don't need to be glued together.
- earthboundkid 18y agoYeah, but you've gotta buy glue anyway, so why not sell you pulp at the same time?
