How much plastic do you throw away?

I just emptied my scrap bin and was a bit shocked at the amount of faulty or discarded prints, support material, odds and ends of filament to short to use, etc.
At a guess I would say about 70%-80% of the stuff i buy goes in the bin.

How about others, are you more efficient than me?

Same here, about 60% I guess... have the Mini for 2 weeks now.

Made a display model of a hand for a nail studio, in 2 pieces. Today I sanded the joint, and tried giving the hand a nice gloss with acetone... BIG FAIL, some white patches appeared on the pink hand... one more for the trash bin :(

Also did an iPhone dock which a friend designed for himself. Already tried 3 times but always near the end, the printer starts air printing... That's 3 in the trash bin...

So far I've been very unimpressed with this printer, and 3d-printing in general...

I would guess about 15% to 25% of the plastic I buy goes into the trash bin, but when I first started 3D printing three years ago it was closer to 75%. Most of what I throw out is support material and raft, with just the occasional bad print. I'm not counting parts which printed perfectly fine but where the design wasn't right--often it takes several versions of a design I'm making before I have everything the way I want it.

It takes some time to learn the ins and outs of your particular printer, what will print well, and what settings work best for a given model. I can usually tell with a quick glance if something I downloaded from Thingiverse is likely to print well or fail, and I don't bother trying to print the bad ones unless I'm looking for a challenge.

I agree with Pleppik.
Early on I wasted at least 20% on failed prints and support/raft, now I would say it is less than 1%, I build raft-less, experience lets me decide when I can get away with no support and what models will fail early on.
My mods make it very unlikely I will get a jam/strip-out and my build surface is trammed and very flat to the nozzle.

My over 60 spools of plastic I thought would not last long, now I'm afraid I will never use it all!

Drew

I used to throw a lot in the beginning.
In time you get used to it, discover good and bad points and learn how to use it to not throw so much. You will even start to think how is more efficient to print an object to use as little material as you can. ;)

Don't worry! :)

I am. The amount of scrap from support material or an actual failed print is fairly minimal, but It does not matter if the part warped or I messed up a dimension - its a scrapped print.

How many reels of plastic have you used? and compare that to the useful items you have.
I'm sticking with 70%-80%

I throw away loads because my print styles need so much support.

I'm with Drew hardly waste anything, I've always been following proposals Drew and Julia on the job and I do not have a greater waste than 2%, also I think the best technique of this forum is to Drew , Roller really do not know anything, always talking but never shows anything, I feel he is a selfish person but also admire him because his experience in the field of printing it shows. Roller excuse me but I think so. In 4 years consumption of one to two kilos per month are I've spent over 100 kilos .

Jose,
I wish this forum would allow those that start a thread to moderate it. I would delete that last post of yours. It is a discussion on wastage, not not an excuse to take a pot shot at roller. Someone who has made huge positive contributions to this forum
.

Shucks Woofy ... Thanks. I have a big plan for December too. Just have to get my crap together to make it happen.

I thank you for your words!. But I'm in a democratic environment and like it. Here I always will express what I feel I am a human, I am not a machine, I think , I feel and I express my taste. If I tell to my good friend Roller I've written here is the result of coming to read and observe the behavior of each of you. The review is positive and not destructive as you seem to understand. I take my friend Roller and I see his deep knowledge on the issues discussed here. So I ask you please respect my education and culture first. At no time did I want to offend Roller even you that I unexpectedly , unfounded criticism. Unlike the observation that I make Roller. Besides not speak their language , I do not have to shut up. I will really love to see the work of Roller learn from. Anyway here I am and I have more time you , watching and learning from all. I can only thanks each of you here and others gone from this forum for one reason or another.


Jose

Well, I guess this is a difference in philosophy. To me, if I make a design mistake that's not a failed print, it's a successful experiment.

In a little under three years, I've used about 40kg of filament. How many useful items do I have? That's a hard question--many of the things I've made were never meant to be useful.

I have to concur with that philosphy ... my workspace has about 10 successful prints on display and half of those are desk accessories ... whereas I have about 20 fialed prints including a nest of extrusion from a disastrous print in a jar that I keep for inspiration.

I just wanted to chime in, I started out throwing away a lot of plastic when I first started. Mostly because I was still learning. After buying an enclosure (the first ones Octave made), a temp mod, and switching to glass build plates with Aquanet hairspray, the only plastic I throw away now is just support material. With the glass plate I can print raftless 99% of the time. that saves me a lot of plastic, escpecially when I'm just printing thin flat logos. And the enclosure creates a passively heated chamber which keeps my abs prints from splitting/warping. The temp mod allows me to buy cheaper generic abs that makes trashed plastic less painful to think about. And to be honest, there are times I just plain dont care about how much support material gets thrown away, lol. I bought the Up! back when it was really the only printer that did support well (although a lot of companies have caught up in that category since) And I expected to be throwing support material away. I HATE splitting models into sections that will print without support and glueing them together when finished. I would rather print with support and not worry about it, and the wasted plastic is definitely worth it to me.

Teamcarlilse, I agree with your observations.
Bought my UP Plus second hand, long time ago, from guy who was moving on to printing in metal.
.i have only once printed with a raft and have majored on Kapton tape smeared with an ABS wash in MEK. Except when using Ninjaflex, which holds to the ali plate on its own.I have never used PLA, as I build things to last, rather than deteriote in sunlight etc. I do not regard support as wastage, quitevthe opposite, it makes builds easier. And yes, experimental prints that fail due to design rather than the printer limitaions I also do not regard as wastage, but as educational learning curve material.

cheers

Peter
