What Type Of Plastic Are Coils/skid Plates Made From?

[GoodAmount]

@jasong Amazing Goo is a good lightweight option. Do you just apply it around the rim? I’ve seen it done like this, but the centre of the coil housing still gets pretty scuffed up.

Annealing in salt is a great idea. I might give that a go before trying hot water - I think it’ll maintain shape integrity better.

I went out for a swing this morning with a fresh skid plate on to a spot where it would get a hammering on bedrock. Below are pics of how it looked after the session (I did reasonably well ?). I’ll track the rate of wear and see how long it lasts over the next few weeks - I’ll be heading out most days, so it’ll rack up hours quickly. I think with the extra material thickness around the leading edge it’ll last longer than a styrene vac formed part, but not sure how it will compare to an abs-pc mix equivalent. Regardless, I can just print another one for a fraction of the price if it does wear out fast. ?

@GoodAmount Nice, yeah seems like ABS is doing good. No plastic will avoid scratches on rocks since it's just a matter of hardness. On your slicer do you just do solid with no infill? What nozzle and layer thicknesses out of curiosity?

Yeah the Amazing Goo I just put on the edges of all my old NF Advantage coils because I got so tired of burning through skid plates. Actually the bottom of the coils themselves stayed fairly intact, just really scratched up. I haven't used any of them for quite some time though since the GPZ first came out. The goo itself didn't really get damaged at all though, and I always thought there was something there in terms of making better coils. The really soft plastic compounds actually wear better than the harder ones since they are self healing - like a skateboard/rollerskate wheel, or rubber. I think there is something there if it can be done to look nice on a 3d printer, that's the problem though.

I think it's awesome that we are almost to a quasi-Star Trek replicator type situation for some parts. Just download a file and print it out, and voila - endless replacement parts for pennies on the dollar.

I’m doing a solid infill, but it’s never quite solid given the extrusion profile is circular and there’s gaps between strings. It’s possible to over-extrude material to reduce the gaps, but I’m using a Stratasys machine/slicer that doesn’t give me that option.  Printing parts ‘airy’ is good for keeping their weight down though.

My nozzle diameter is the standard 0.4mm and layer height is 0.25mm.

I’m super interested to hear how you go. And yes, bring on the Star Trek replicator. ?
