Re: PETG Settings

I guess you're not using a raft. Supports have very little "footprint" surface area for sticking to the bed. They will adhere much better to a raft, where they will actually be welded to it.

SCP is the way to go, as ABH mentioned. It'd be nice if IdeaMaker had this functionality built in.

Re: PETG Settings

I print Edge PETG from SpoolWorks on PEI, using Raise PLA profiles, 230-240º extrusion, and 80ºC bed. Works perfectly every time.

Re: Has any user done anything to address health-related issues during 3D printing?

FYI and FWIW, this is the only thorough study I'm aware of:

http://www.z-temp.co/Emissions%20from%2 ... inters.pdf

It shows PLA emitting a 2-3 orders of magnitude fewer ultra-fine particles and 1-2 orders of magnitude fewer VOCs than ABS.

Re: Be aware - Actual buildplate temp lower than temp setting

If you're really serious about measuring bed surface temperatures, I'd suggest you tape thermocouples directly to the surface being measured. I'm not saying your non-contact measurements are wrong, but I'd have a lot more confidence in the data if it was via contact, as emissivity and other factors ...

Re: Buildtak problems - nothing sticks to it

I'm also very happy with PEI. 60ºC for PLA and 80ºC for PETG, no problems.

Re: Z-stop Spring by Julia Truchsess

I've noticed fairly big variations in Z depending on spring clip tension and location. Glass is not perfectly rigid and can flex. The bed can move 1/2mm or more depending on where the clips are, how many you use, and how strong they are, so it's important to be consistent.

Re: New idea for insulating a hot end rapidly

The key parameter is insulation, or "k" factor. The insulators I sell for Zortrax printers have a k factor of 0.48. And installation couldn't be much easier - a couple of silicone o-rings.

There are a zillion sizes in the popup menu, including 300 x 300 x 8. Still maybe cheaper to make your own.

Re: Black MagiC Conductive PLA

I have some Black Magic, I forget if it's PLA or ABS. The biggest problem I had with it was lack of layer bonding. Bonding to itself was bad enough, but generally with conductive material you want to do a multi-material print with some non-conductive material and this was for me a total fail, it wou...

Re: ABS - partial insufficient strength of printed objects

There are a few things you can do to strengthen parts: • Use thicker layers. Thicker layers carry more heat energy from the extruder to the print, increasing layer bonding. • Use more shells. Shells contribute more to part strength than infill. • Increase the amount that infill overlaps the inner sh...

Re: Carbon Fiber Print surface??

You can buy a 0.25" MIC6 aluminum plate from McMaster for $47. Al has twice the thermal conductivity of glass, but they don't sell it in smaller thicknesses.

Re: Carbon Fiber Print surface??

I'm using 6mm borosilicate glass plates that have been ground flat. They are excellent, but they increase the heat-up time by a few minutes. Other people like PEI sheets. I have a sheet of it around, but haven't tried it yet. PEI is great, but it doesn't make your glass flat. Where do you get the g...

Re: IdeaMaker feature requests

+1 for auto-arrange. IdeaMaker is the only slicer I've ever used that doesn't have this feature.

Also +1 for more shortcuts, especially for "duplicate". Ctl-D should make one duplicate of any model(s) selected.

Re: Cyanoacrylate (Super Glue) to greatly improve adhesion

I've been using PEI bonded to glass with 3m 486 for quite a while now and love it for PLA and PETG. The only problem I've had was that Form Futura "Stone Fill" PLA bonded to it permanently and I had to remove that PEI sheet. I never experienced this issue with any other PLA or PETG, prints...
