What do you use to cut this?

[harmonylab]

We're having trouble cutting this thing. We use a long diamond bur to cut it but it's very troublesome. Does anyone know a better method? We're about to try diamond discs but not sure on the specific type to try.

Why did you use a sintering wall for this small of a bridge? You only need that for large span bridges. If anything, put a few sintering pins on it and use a flat tray to sinter.

If you do have to cut those off, MAKE SURE you use a wet handpiece to reduce heat.

Waste of material and tools for a short span like that IMO...

mini diamond disc will be fine...

that is also not a very efficient support structure.

I'd use a high speed diamond with water.

Because it warped during sintering. We'll try wet handpiece. Thanks.

If you mill with sintering drops and place on a flat tray, you won't have any warping. Sometimes those thick walls around frameworks will cause the bridge to crack.

also - i never understood the logic of those sintering walls....you are robbing heat away from your units.... its creating mini heatzones or lack of a good heat zone. I'm a fan of the delcam or Sum3D support structures

Make the wall thicker 4-5 mm with S form ( black ) so you dont need the other parts and you save material ( not 2 times offset ) , if the object is to high make additional sinter pins but only on top of the wall enough to be stable on the ground. Use a small diamond but slowly with water so you must cut only 4 pins. But this bridge is very straight if you take care only on sinter beads it ok.

I agree. I couldn't ever get a consistent result from that type of sintering wall.

what program makes that? ZZ CAM?

also...it looks like it's pretty hard to stain with it in the way

 

[Smithwick0208]

Glidewell's nesting software allows that type support.

 

[eyeloveteeth]

so it's VHF software? i've never seen glidewell cam, but the glidewell mill is the VHF right?

it's mayka from picasoft. it's very limited and buggy, and my only 2 options are peripheral and internal supports. internal support wasn't very effective at all, but the external connector always gives excellent results for us. I really wish I could use a different cam. sigh.

it isn't all that hard to stain.. cutting it is a b**** though.

you can!
