Re: Water-fused plastic as a print medium?

From what I have gathered in the datasheet, they are plastic beads covered in a PVA glue. Water melts the surface and when the water evaporates, the glue sets again. Grinding the beads up will probably leave a lot of the powder without glue, because it is only applied to the surface (from what I hav...

Re: BrundleFab - a powder thermal fusion printer

Neat way of building parts. I never really considered aluminium door signs (nor did I know of their existence) but 0.25mm (0.01") aluminium should be strong enough if the design is right. I don't know if $2 is a bit much for the thickness and surface area, but it is more available than most sources ...

Re: Pip-Boy 3000

There is a design floating around that does indeed have that included in the model, but I couldn't tell you where it is, I don't know.

Re: BrundleFab - a powder thermal fusion printer

Heating the printbed would indeed help the speed. If you only need to push the temperature past the melting point by a bit, there is no need for 4-5 cycles (and no more smoking heat shields). The rising heat passing the printhead might be an issue, but that is a fixable problem. While I totally agre...

Re: BrundleFab - a powder thermal fusion printer

The Multi-Pass technique looks great. I can't believe the strength you are getting and how unsintered the surrounding powder is. My only experiment with Nylon sintering only left me with weak wire frames. Your sugar has surprising strength for the fact that it is sugar. The smoking heat shielding is...

Re: BrundleFab - a powder thermal fusion printer

On Plan B, the last used settings were layer height 0.18mm, with inkjet printing at 250% compared to 96DPI and 3 sweeps per line (3 sweeps per 12 nozzles of width). This much ink and coverage was needed because the cartridges deposited less binder than it deposited ink. Looks very promising. That is...

Re: I am back...

Hello Hello, With that, I think the entire core of the Ytec forum is now moved to the new forum. That conversion went smoothly. I already like this forum better than the previous one, previews, easy and reliable login, uploadable attachments to the actual site, signatures (though I never used them)....

Pip-Boy 3000 Mk IV

Got the Fallout 4 version of the Pip-Boy printed. Got it with an actual geiger counter, or have it playing games (or just show a neatly painted version). Share it here.

Pip-Boy 3000

Show off the great 3D printed Pip-Boy 3000 you made here. Modified it it for a bigger arm? Got some buttons working? Made it into a fully functional computer? Share it here.

Portal Turret

Show off the great Turret you made here. Got it to open and close, got it to sense whether it has fallen, got it to fire actual bullets (either just the tip or the entire bullet)? Share it here.
