[Résolu] Trying to print this in Paramount3D  

RE: Trying to print this in Paramount3D

@ssill2

Sorry, I posted it too,  

RE: Trying to print this in Paramount3D

turned out great!  not crazy about the chin though.  will that look better when I can print with a soluble support directly attached to model?

RE: Trying to print this in Paramount3D

looks like it came out great 🙂 

RE: Trying to print this in Paramount3D

@swiss_cheese

yeah my boss is going to love it lol.  Now I might print one for myself lol

RE: Trying to print this in Paramount3D

so I did get this to print.  I wasn't crazy about the quality though and after working for a few days with @swiss_cheese on a different filament issues, I realized that my settings were WAY off.  I think I'm going to try to print this again.   I'm currently printing something I designed in blender for my wife, and once I get that successfully printed I'm going to try the hannibal mask again.  Her project is in white Paramount3D PETG so I'm thinking the settings should be identical for the army green.  We'll see!

The same author does this mask

https://www.thingiverse.com/thing:4275874

and I wear that every time I go out lol.  I get tons of compliments on it.   I'm currently working in blender on a kylo ren mask that will fit that lafactoria3d base. I plan to use the MMU2S to print that with black and silver lol.  

Now; that is a mask I need:->

RE: Trying to print this in Paramount3D

@stewartr

hey, I say if I have to wear a mask, I might as well have fun with it!

RE: Trying to print this in Paramount3D

@ssill2

I love having a 3d-Printer! When everyone was scrambling around paying Amazon £10 for a single disposable mask I'd already printed off a few of these https://www.prusaprinters.org/prints/29745-respirator-mask-brasil-xs-s-m-l-xl. The Prusa Galaxy Black one (still) gets the same comments I suspect you get;-> 

I'm toying with the idea of getting the front-plate from yours and adapting peter m's design to make them fit:->

Hey - if I have to wear a mask, I might as well make it obvious I do it out of necessity...

RE: Trying to print this in Paramount3D

@stewartr

yeah, I'm doing something similar with a model of kylo ren.  I took the full model someone had posted and sliced it up in blender and I'm fitting it to the base for the LaFactoria3d one the vader and hannibal use.  I'm kind of waiting on my MMU2 unit though.  I'd like to do the silver stripes as part of the print and not painted.

I printed it once, it was 50h print lol.  I wasn't happy with the first cut of it though.  see attached

@ssill2

Whilst this is sliding a bit off-topic, I have to say that Blender is my 'final frontier':-( I can use it, but barely. And I don't need to use it often enough to get proper practice with it. (Although if it could do a Boolean cut with text into a solid block properly, even after all the cleaning up of the text mesh, then I'd probably use it far more often (I like writing letters;-)

As for MMUs though; I've had enough problems in the past with mine that I've made a few recommendations for how to sort all the issues that seem to crop up 50% of the time. See my responses to  https://forum.prusa3d.com/forum/original-prusa-i3-mmu2s-mmu2-assembly-and-first-prints-troubleshooting/first-layer-calibration-mmu2s-constantly-loads-and-unloads-the-filament-to-the-nozzle/ if you have any problems with that contraption...

And, yes - I had thought of using Blender to project an image (reduced to minimal colour) onto the mask I was using.

RE: Trying to print this in Paramount3D

@stewartr

thanks for the heads up about MMU.  it was an 8 week lead time, so that'll put it roughly at the beginning of march timeframe.

Blender is a great tool.  I've gotten much better at it for doing 3d printing stuff since I started a couple months ago.  I had used it for years doing animation stuff and I'm sure I only use 10% of it's functionality.  Anyway, back on topic.  I'm cautiously optimistic I have found the sweetspot for this paramount3d petg filament.  I've literally spent about half a spool so far on getting a good print.  how I got anything printed before swiss_cheese helped me get my zOffset dialed in, I have no idea.  I printed the hannibal mask in army green of the paramount filament.  took several tries and it's why I started this thread.  I decided to standardize on this as my petg filament so I ordered white, autobot blue and decepticon purple.  I designed a shelf for my wife to fit in our bathroom that replaces the electrical socket plate and adds one with a shelf on it that fits our particular bathroom.  Since recalibrating my zOffset I'd had the worst trouble getting the paramount stuff to print.  it seems that with a zOffset of -0.298,  the extrusion multiplier needed to be dialed back to .9    Any more than that, I had filament build up on the nozzle and drop blobs in random places.  So far this print looks pretty good.  I'm printing in the army green not to blow any more of the white.  I spent half the white spool doing prints only have them fail six hours in.

But I do feel like now that I know more than I did, I can do the hannibal print better.   I will definitely post pics.  I then have to go through all my filaments and redo the profiles with this optimized zOffset, but the prints will look so much better!

RE: Trying to print this in Paramount3D

@ssill2

Remember that you can save, on the printer, different z-calibration levels for each 'sheet'. The problem is how many characters you can use, so if you do the same for different plastic types as well as sheets it'd be best to come up with come sort of coding scheme.

I seem to get away with doing it by 'gut-feel', but I'd not recommend that. As an engineer I should recommend keeping notes of every change and the outcomes. Hey ho...

Seriously though - have a look at those MMU hack prints I pointed you at. At the very least, and even if you manage to get your one working perfectly first time (as ~50% seem to do, and I hope a higher percentage!) then those buffer-side parts give you a bit more space for your fingers whilst feeding a new spool of filament into the unit. I'd seriously suggest the MMU mod' as well since it makes uncoupling the buffer (I'm really space constricted, so I have no option but to use it, and it works fine for me now) from the printer a hell of a lot easier. The only real friction I have now is in the buffer-spool side, and as I mentioned I figure this is actually a good thing.

Checkout posts from @jsw and @joantabb for far more useful info and mods about MMUs.

All the best, and I look forward to seeing the result!

RE: Trying to print this in Paramount3D

@stewartr

this is great info!  thank you very much!

Here's what I'm working with as far as an enclosure.  I'm quite interested to see how large the mmu stuff actually is.

RE: Trying to print this in Paramount3D

I just opened a sample to PETG.  It has to be the stringiest stuff I have ever printed.  I think it a fluke because I have printed a dozen and all were ok till this one.  

RE: Trying to print this in Paramount3D

@cwbullet

I had to make the extrusion multiplier on the paramount .9 to avoid getting a bunch of extra filament buildup.  but with that it prints fine, no strings.

RE: Trying to print this in Paramount3D

@ssill2

Thanks.  I will try that.  I did print 12 or more other samples without stringing - maybe I got lucky.  

RE: Trying to print this in Paramount3D

Here's what finally worked for me.  I do get warping on one of the corners, but otherwise, the filament prints very nicely now.  I'm quite surprised I got the hannibal mask to print at all given how off my settings were initially.  finally back to getting stuff to print lol

RE: Trying to print this in Paramount3D

Good to know. Some filaments are frustrating.

RE: Trying to print this in Paramount3D

@cwbullet

I have a print going of the light socket shelf in Paramount3D white right now with the .9 extrusion multiplier.  I printed about half of it yesterday in the army green just to prove out the settings and that worked fine.  another 14 hours to go.

RE: Trying to print this in Paramount3D

Correction,  .89.   so a small piece of filament show up when printing infill.  fortunately I was able to pull it with tweezers during the build.   So build still going cleanly it looks like.
