The question is whether it's workable.

So you don't know that then? ;-)


have you only just realised that?

No, I've know it for some time now. ;-)


Obviously not, as this question was only brought up a day or 2 ago.

I was just trying to better understand what you thought might be a
solution (it happens that there quite possibly be no need in the OP's
scenario but ..). It wasn't your question I was questioning, it was
you and your direction. ;-)

Print things as hollow as is workable, fill with molten plastic from the kitchen bin. Result: stronger, tougher, much cheaper.

Define 'much', considering the cost of any process required to get
said material in any workable state and your time etc?

processing is fairly trivial.

If you have a problem with me asking questions, honestly I don't care.

No, I have no issue with you asking questions, it's making suggestions
that don't to have any practical need or tangibility that confuses me.

Cost & durability issues are AIUI some of the prime issues with 3d printing.

FWIW, I've just printed a whole batch of things at 100% in PLA and
didn't consider the material cost for one second.

great. That of course adds nothing to the point

What if these draw dividers were for small component draws ... and
even if they weren't, for any (d-i-y 3D printable) divider is hardly
likely to consider the one roll of PLA you might need to print 100
dividers "steeply expensive", especially as yet we have to find out
the total cost of using 'recycled plastic' for any infill?


I had rather more uses for this in mind than just printing drawer dividers

Fair enough.

The cost of the plastic in the bin is nothing. The cost of the electricity to heat the oven is a few pence if you're not cooking any time vaguely soon.

Ok ... but not including the damage to your lungs and the cost of your
time / redecoration after the fire. ;-)

why would you set fire to it? Why would you use a plastic with a fume problem? Do you know anything at all about plastic processing?


The question is simply is there a combination of plastics this would be workable with?

Ok.

PLA & HDPE are too close in melting point, PET melts much lower but I've no experience working with it.

I wonder if anyone else has considered this solution and come up with
an answer? If not, why not ... ?

Cheers, T i m

It should be fairly obvious they have.
