Polishing Iron PLA Prints...?
As I was polishing prints made with our Stainless Steel PLA for the last blog post on wheel polishing, I began to wonder if the same could be done with our Magnetic Iron PLA. After all, it also has powderized metal in it, why hadn't we tried to polish it already?
I put this version of the famous Thingiverse owl to the test by attempting to polish it on the bench grinder with a polishing compound. The result was... a slightly shinier owl, but certainly not as impressively shiny as SSPLA after polishing.
So can you polish iron prints? Kind of. A different method (or simpler shaped print) might produce better results.
