The spikes comes from "Detect Thin Walls"!
Why? I don't know!

@ringarn67

oh interesting.  I'll uncheck that and see.

RE: How to print with glass

yes you are correct.  unchecking that makes them go away.  Good to know!  Thanks!

RE: How to print with glass

so before I try massive number of perimeters I'm trying with aligned rectilinear at 315 deg, which is the angle the original author of the printing with glass I article I started with used, but in S3D it's done as -45 deg.  at .6mm the print still looks reasonably clear, more reasonable than the previous value.  at the same height, the infill starts being filled in from the middle, and not from the left wing tip as at the start of the model.  I don't see any way to control that in prusa slicer.  

Anyway, it's doing height .8mm right now and it still looks pretty clear, so I'll let it go.  I think the all perimeters thing might give it some bizarre optics.  I'll see how this turns out though.  Even with 100% infill, this model only uses about 7g of filament so I can try this many many more times lol

I have about 9-10 rolls of transparent PETG.  If you nail down the settings for Batman logo, I will do comparison prints of each.

I think I'm close with this latest one.

Here's what it's looking light at 1mm z so far.

I'm anxious to try this some other transparent petg filaments like the Taulman T-Glase and some sainsmart I have.  265C is too hot for the T-Glase though, tried it briefly last night, so I'll have to lower it slightly, but leave all the other settings.  Haven't tried the sainsmart pro petg pink transparent I have.   But in theory once I get this figured out it should work for most transparent filaments just adjusting for temperature I would think.

RE: How to print with glass

I have some other suggestions but I'll be out, believe it or not at meetings most of the day, when I return I'll write out the other suggestions.

Enjoy

Ok, since this seems to be working now, here's the latest version of the .3mf.  Again, this is being done with AtomicFilaments clear petg, so you might have to lower the temp from 265C.  265C is the top of the range on the spool label for this stuff.  After this completes I might try with sunlu clear and the other ones I mentioned above.  I could see this looking pretty cool with colors.

As always I'll wait with bated breath! 🙂

@ssill2

Ok.  I have one roll of each of the clear PETGs.  

RE: How to print with glass

@cwbullet

this thing is at 50% done, 1.3mm high so far.   I still looks pretty good.

RE: How to print with glass

I've been able to get almost clear pieces by using transparent ABS and doing 100 percent infill and after the print is done, stroking it gently with a mop brush dipped in acetone. 

RE: How to print with glass

@annier

yeah someone else mentioned the clear abs as well.  I'm trying to avoid printing with ABS, but I'll definitely keep that in mind if I need to do something that's needs a higher temp.  PETG has the advantage of not having all the fumes and not needing to be hooked up to ventilation.

RE: How to print with glass

@annier

What brand of ABS are you using?

RE: How to print with glass

Wow, the Taulman T-glase is looking awesome!  It's nearly done,  just had to lower the temp to 245C

RE: How to print with glass

Not bad!

RE: How to print with glass

Now printing in Sainsmart pro PETG translucent pink.

Have you tried, or do you use acetone vapor smoothing? you keep talking about applying with a paint brush (Mop brush) do you find the results are better this way compared vapor smoothing, or are you going for a different look then vapor smoothing offers?

Also could you post some images of the results of using the Mop brush? if you can, would it be possible to see both successes and failures of this technique to compare?

I currently have only vapor smoothed and have had both good and bad results depending on the model and also how I orient it in the chamber for smoothing.

Thanks in advance
