Friends, Romans, Countrymen, lend me your ideas. Look at the picture of the dual extruder tip cleaning fences and give me your thoughts on what they could be used for.
Background: I have recently added a 3D printer to my lab to prototype chemical laboratory accessories.
I purchased a dual extrusion Makerbot and I love it.
Technical Details: Aside from the waste produced from being a noob at 3D printing, there is also a lot of built in waste from raft and tip cleaning fence material. Turning off rafts and supports does not save filament because these help ensure a successful print. If the print fails without rafts and supports, then you have still wasted a lot of filament.
So get those creative juices flowing, and comment on what you would use these tiny little fences for. Toys? Rear view mirror bling? Let me know.

I have read so many articles or reviews about the blogger lovers except this piece of writing is
actually a nice paragraph, keep it up.
Can’t it be melted into new filament somehow? I also just purchased a 3D printer for the lab–alas mine is a comp.chem. one–and I’m concerned about filament waste. I read somewhere that the nozzle cleaning process, which requires the waste of even more filament, can be hacked by actually printing a roll of filament; I guess I’ll have to try it.
My son and I toyed with the idea of building a heated filament extruder, but we thought it would be of low quality. This is a “somebody ought to do X” situation. It is lightweight. I’d be willing to ship my filament waste to a recycler for them to reextrude, but have never heard of such a program. Someday, maybe. Thanks for commenting!
