@reprapryn Wait, _printed_ electromagnetic coils? I assume you're using like SLS or something, not FDM?

Also, welcome back!

#Blender3D Fedi: what should I use to remove resin traps (internal closed cavities) from models designed for #Resin3DPrinting ? I know about the 'separate by loose parts' method, but this only works if the cavities aren't attached to the interior, which unfortunately they often are.

I can fix this manually by cutting faces from the inside, but this is tedious. Chitubox Basic can _detect_ cavities (with some false positives), so surely the technology to do this faster exists?

@mia @lanodan @jamie @trashpanda My guess? Nobody wants to pay for it, and the undertaking is too large to be a hobby project. It's the same reason why our slicers are fundamentally 2.5D and will likely stay that way forever.

@Polychrome I fortunately live in a place where I don't have to choose.

@FinalOverdrive @mia @kaia This right here is why I basically don't enjoy the company of cishet dudes. Among other things, it is _incredibly_ dull, since everything is either pecking order assertion or trying to jump above. It's dull, it's not worth doing, and it basically makes any other interactions above a very basic level impossible. Waste of time in general.

@FinalOverdrive @mia @kaia You know, when it's not casual homophobia, sexism, transphobia, racism etc.

So, one unexpected Saturday delivery later, we have _another_ tuning thread! This time, it's HIPS filament from Gizmo Dorks.

I feel that HIPS is a criminally underrated filament for printing with, as it has all the properties of ABS (high impact resistance despite low density, slight flex, temperature resistance, easy post-processing, etc), but _un_like ABS, it also:

- Dissolves in limonene; and
- Absorbs virtually _no_ moisture.

@3dprinting These two advantages mean that firstly, you can smooth (and weld) HIPS without having to use acetone (limonene is _much_ nicer to work with), but also that you don't have to worry about dry storage _at all_.

HIPS sees relatively low use in FDM printing - it's mainly used as a soluble support for ABS - but in other places, it is _very_ widely used. For example, if you bought a plastic miniature recently, it was _almost certainly_ made of HIPS.

@3dprinting I've been trying to find a good source for the stuff, and Gizmo Dorks showed up on my radar at around the same time as Tinmorry.

So now, I have to swap _back_ to my CHT nozzle, find my Z-offset _again_, but at least I don't have to dry anything! Let's see how well this HIPS filament performs.

@3dprinting PIOMAs here are going to be identical to how I'd normally run ABS:

- 260C on the nozzle, 110C on the bed, 55C chamber
- 45% fan
- EM of 0.925

I'll also have to test shrinkage in addition to everything else.

@3dprinting So, packaging. Plastic spool (boo!), but resealable bag (yay!)... except in this case it's mostly pointless.

First extrusion, smell test! It has a _very_ tarmac-y base note, but it's not nearly as pungent as most ABSes in my experience. Not nearly as low-odour as, say, Fusion or Paramount3D, but better than Polymaker for sure.

@3dprinting Just to put this filament's lack of use into perspective, there's no 'generic' profile for the XPlus-3 in Orca Slicer for HIPS. This might not _sound_ like much, but there's a generic for _PVA_ in there, of all things!

For fun, Gizmo Dorks advise 230-250C on the nozzle and 110C on the bed. That's basically typical for ABSes, and the main reason I shoot higher is because the layer adhesion bump really does matter. Plus, VzBot folks do it, so it's not just me saying that.

@3dprinting Fun discovery I just made - apparently, you don't even need limonene to smooth or weld HIPS: turpentine will do.

@3dprinting OK, Z-offset has been re-tuned, time for the first step: a voluflow racetrack. This time, since we're back on the CHT, it's 10 to 40, in steps of 1. Let's see how close we get!

@3dprinting The smell this stuff has while printing is... interesting. Even through a filter, there's a base aroma, which, while hardly _pleasant_, is nothing like the awful smell some ABSes can have. I'd say in this regard, it's definitely middle-of-the-road, but if I had to pick between leftover smell from most ABSes and this - yeah, I'm taking this!

@3dprinting I don't even have words. 40VF, with _no_ issues. What is this material, seriously.

Gonna have to re-run from 10 to 60 just to see where it fails! Nothing I have ever printed with has _ever_ flowed this well before.

Plus, _damn_ that extrusion is _smooth_.

@lucy Those 50-in-1 hygiene products with marketing like IT'S FOR REAL DUDES SO MANLY LOOK AT HOW MANLY WE ARE that combine shower gel, shampoo, toothpaste, hair tonic and morning coffee always weirded me out.

I accidentally a cool effect today with my #MiniaturePainting. I didn't do this intentionally - both the colour _and_ the marble-like effect are complete accidents.

@dalias Yeah, this is a huge annoyance of mine too. It inherently drives a language, and its standard library, towards compiler development, despite this being a fairly niche case. Usually at the expense of other things.

@jamie Sounds familiar. In my case it's mostly fan noise, when it's not the XPlus-3's shitty motor resonances at low speeds.
