Fwiw, SpaceX also 3d prints quite a bit.
A bit of convergent evolution here.
- WWLink 4y agoWhy not try something different? Just because spacex does something well doesn't mean everyone has to copy spacex.
- pmayrgundter 4y agoI'm not making that argument. SX picked rolled steel (really, a custom variant) as a good tradeoff for performance, durability and cost. That was trying something different, and Relativity's goals for low-cost and reuse look much more like these goals
- WJW 4y agoJust because most cars use round wheels doesn't mean trying different wheel shapes is necessarily a good idea. Sometimes there's just a clear best way of doing things and there is no benefit in diverging from that.
- shantara 4y ago>SpaceX also 3d prints quite a bit. Pretty much every modern rocket engine manufacturer does. The engines have a lot of unconventionally shaped pipes that could be manufactured as a single structural element using 3d printing to avoid the need for extra welding and potential points of failure.
