I think Tyler's problem was going to KS too early.  He priced based on the BOM + markup, but didn't realize that the R&D he still had to do also cost money.  He also painted himself into a corner by offering a grinder to the higher tiers, which is a whole other complicated thing.

Ah, the sad stories that could be written about KS campaigns.

Re: Waste

I saw this in the April fools Solipony thread and was wondering if this is real.
I know it's supposed to be a joke but we could use old or cheap grinders to make pellets or smaller particles that can be then used with Elmoret's Filastruder.

Re: Waste

The problem is contamination.  Any grinding may cause shavings from the grinding process to drop in with the pellets.  Extrusion of filament with this contamination could cause the extruder to clog when making new filament. 

Not that this isn't a worthwhile idea.  I'd love to be able to cut up some old prints to make new filament. In fact I may be able to do so with some of the pre-load extrusions from the hot end before printing as this would be close to virgin, but I'd make sure that I have fresh pellets with it.  Probably about 25% recycle... when my filastruder arrives. smile

Re: Waste

The big thing here would be a melt filter. I have some parts on hand, but no time yet to experiment.

Re: Waste

That blender is awesome!  I bet the thing could be a suitable grinder!

Re: Waste

I tried creating ABS slurry from my waste so that maybe prints will start to properly stick to the bed.
No luck so far- after 3 days of keeping rafts in acetone I now have a soft blob of ABS. Anybody know how long it takes for that stuff to dissolve? Do I have to use ABS shavings instead !?

I went with PLA for that very reason, only to find out that it can't go into the yard waste or recycle bin. I don't have a yard, so I can't try to compost. Has anyone successfully composted bad pla prints?

Re: Waste

You can only do 15-25% recycle with ABS. Though I can't tell you where I got that number, I was reading about it the other day.

Re: Waste

With all the experimentation of new materials I am curious if there's some sort of material that can be easily recyclable or compostable. I guess it might be time to buy a filastruder and breaking it for science.

Re: Waste

Has anyone seen this. I have been keeping an eye on this page. I don't know if anyone has actually received a ramen kit yet. I would love to know how well it works. I have blown $150 on much worse. (some scandalous bachelor parties come to mind)

On a side note, they have ultra cheap filament that they make themselves.

Re: Waste

They haven't shipped a Ramen. I don't think they've shipped any filament either.

Re: Waste

At $150 that could be an expensive crayon drawing. There's no engineers I know that would try and sell you a physical object based on a drawing they did when they were like 6 (well I wouldn't anyway).
A working prototype would help them quite a lot, the concept is good, I have heaps of scrap and failed prints already, plus the suggestion here of blending scrap with virgin pellets is very sensible indeed.
Kind like when SD first announced the SD3, and the metal parts were all hand made, with dints and gouges. .. .. actually I think this pic is still on their page somewhere, but at least it showed there was a physical object, that looked like it would actually work.

That was good. My favorite part was when elmoret shut them up. Now that is how you stand behind you product.

I just loaded up my first spool of PLA after several weeks of ABS. and i must say i may be hooked. the parts are stiffer, they stick like hell to a hairsprayed glass bed, and absolutely no warp issues! (switched to the PLA roll after catching hell trying to get the idler ends printed warp free in ABS for a set of rostock parts.)

ABS has its uses. for when you need a part to come into contact with higher temp areas (extruder fan/carriage), or when you want a part you can bring to a nice surface finish quickly and easily with acetone vapor. but other than that, i think i'll be joining you on the PLA quest! for great justice!

Re: Waste

PLA works great, but be aware, it is a lot more brittle than ABS. It doesn't flex, it just fails.
It also is not so great at fine detailed models, as the ooze tends to diminish the details.. and its a PITA to get bridging or short-layer time layers working (it tends to melt very badly when doing for example, the top of Yoda's head) without a fan

So if you want a thin walled durable piece, then use ABS. If you want fine surface detail use ABS. Everywhere else, you can use PLA.
