What do you do with your empty 3d print spools?

I'm getting a whole sh*tpot of empty and near-empty spools again.

My SIL used to take them for craft projects but she's said that she has too many and does not want any more.

Our SID's local trash hauler says that they do not want them (in the recycle containers).

My empty stack is now approaching three feet in height!

What options are there, other than throwing them in the regular dumpster as landfill fodder?  Keep in mind that what I have are mixed brands and types of unknown plastic composition.

RE:

Disincentives to have non recyclable packaging regulations?

Probably nothing will happen before we are faced against the wall as a society and it is too late?

Scientists have been vocal but $$$$ is king.

It's the black ones that are most difficult.  Robotic sorters can identify lighter shades for recycling.  Black ones often defeat the scanners.  I have tried putting large numbers together so that it's worth a manual sorter getting involved (advice from recycling dept) but I don't know if they actually do so.

Cheerio,

Or we do buy spools made with cardboard from manufacturers which are already make them (Polyterra and others).

RE:

Just put them (Polyterra) on my list and I will be on the lookout for more manufacturers that do that.

Already put notes to some of my local providers to feedback to their suppliers that it would be a selling point to have recyclable spools.

Currently, I use the black plastic spools for wrapping up cords, rope, electrical cables, extension cords, etc.

RE: What do you do with your empty 3d print spools?

As I live in Vienna and Prusa is near I source lots of material directly from Prusa. Maybe we should create something like a petition collecting people who want Prusa to sell filament on cardboard spools in the future? Is it worth a try? And if a big supplier is starting doing that I am sure others will follow.

Best regards, Clemens

There are also Companies like dasFilament, who just get rid of spools.

They give you files to print a spool once or order one and you get your filament tightly wound and held in place by cable ties. This reusable spool is in two parts and you can securely place the filament inside, put together both halves and then snip the ties. That way nothing has to be wound manually and nothing will unravel itself.

I use them for a while now and I like them. You also save 1€ per spool, if you buy it that way.

Yes, it's the MasterSpool thing. Better than reusable or recyclable : no spool at all. I prefer this way and it's easy to find.

RE: What do you do with your empty 3d print spools?

But my problem is, that I normally have about 50 to 60 spools of filament at home - so in that case I would have to have 60 of these master spools? Is there a way to use a specific filament on such a master spool and when finished you take off the filament (for example using a rope or something to keep the filament in good spooled shape) and put another filament on it? I don't like to print 60 master spools (another 10 or 15 kg of material).

Best regards, Clemens

I am now on the search for the master spool concept! 🙂

RE: What do you do with your empty 3d print spools?

I used to buy Sunlu without the spool and use their reusable spool, but they appear to have stopped selling them.

I see Prusa are using cardboard centres with printed sides if manufacturers like/need a hard sided spool for spooling up the filament could we find some way to return the sides for reuse? We did this with glass bottles I know they were returned to a physical shop but we need to find a way to re-use this product as I'm sure manufacturing them uses a lot of energy and only a percentage of them can be and are recycled.

Are we happy to pay for this to happen? Do we ship them back, or do Prusa pack a return label with each spool and add the cost to the filament? Should we pay a deposit for the spool and have it returned when we return the spool, could the cost be worked into a subscription service? Should we get discount points for returning spools?

Food for thought

I vote no, just another slippery slope. Filament is expensive enough already. I've you feel stongly enough to pay then send them to Prusa, I'm sure they'll reuse them for you.

Should we pay a deposit for the spool and have it returned when we return the spool, could the cost be worked into a subscription service?

I vote definitely no, ditto low friction incline. Subscription services are wet dreams to vendors, constant cash flow, lovely jubbly.

Some Polyterra spools I've got lately were made from pressboard, a material somewhat like aspenite. Surely to goodness they could be reused though. The problem would be collecting them and returning them to wherever the filament is made.

LOL, maybe this is one situation where the landfill is the correct tool for the job.

Landfills are not really a thing over here anymore concerning household waste. It generally gets incinerated in energy retrieval facilities.

They should do more of that kind of thing around here.

RE: What do you do with your empty 3d print spools?

I would love to see one of my hobbies create as little waste as possible. In any case, rolls of cardboard could be a way here. And if you need hard sidewalls on the spool that run cleanly on ball bearings, for example - well, I suppose we can find an "adapter solution" for that.
