I plan to order some PVA and HIPS to experiment with, but I get the feeling that I will only want to use it when I really need it.
I actually am interested in experimenting with using HIPS by itself for some special-purpose prints. I understand that polystyrene is useful for certain electronic applications because of its dielectric properties, so I wonder whether HIPS filament might be useful for printing certain things like radio coil forms, high-voltage insulators, etc?
Dual Extruder Upgrade Availability?

No idea on the HIPS. Jin might know - he's printed with it. (It might be better than the PVA for support too - I've never printed ABS or HIPS.)

Be careful with those, because the nature of fused-filament 3D printed objects works against you.NF6X wrote:high-voltage insulators
Even with "100% infill", there's plenty of air within the object: the creep distance will be roughly a straight line from one side to the other and the breakdown voltage will be about the same as the equivalent air gap.
As long as you don't depend on a coil bobbin to double as a high-voltage insulator, it should work fine to hold the wires in the proper orientation. This PLA doodad mounted a slit ferrite core for a Hall-effect current sensor, with everything floating on the hot side of the line:

Aha! I hadn't considered the porosity of the printed object. Thanks for pointing that out.

Re: Dual Extruder Upgrade Availability?
sorry to hijack a little, but peaking of the upgrade - is there any option of having the dual extruder already installed?
I know I could do it but would feel better knowing it was installed by someone who definitely knew what they were doing.
The biggest upgrade I've done was adding a heated build plate to my printrbot play...

Re: Dual Extruder Upgrade Availability?
Right now the dual upgrade only comes as a kit. (It's really not hard to install though if you just carefully follow the instructions. Takes a few hours one weekend afternoon.)

Re: Dual Extruder Upgrade Availability?
Alright you've convinced me. I'm going to place an order for both the printer and the dual extruder today. Really excited!
