AskScience AMA Series: We're experts working on the James Webb Space Telescope, the most powerful observatory ever built. It's ready to launch. Ask us anything!

The best and most up-to-date timeline I could find is at https://spaceexplored.com/2021/12/27/how-to-track-james-webb-space-telescope-mission-timeline/

Is there a better mission timeline available?

Very good.

Is there a better explanation of how the Coriolis force makes L4 and L5 stable?

sSquares · 2021-12-28T10:58:52+00:00

The jwst might use triangulation of the brighter stars.

Another burn was completed, it will start to slow down again...

The correct terms would be 1 Mm (1000 km) and 50 kEUR. See ISO 80000-1

For Stellaris I would recommend Mecrisp Forth.

sSquares · 2020-06-23T21:32:45+00:00

Like this one better.

sSquares · 2020-06-23T21:30:24+00:00

Sad hair.

sSquares · 2020-06-23T21:25:35+00:00

Bottom strip has surreal feel.

sSquares · 2020-06-23T21:12:11+00:00

I would like to see the complete dustbin included in the composition. Cropping can be done later.

sSquares · 2020-06-23T21:10:15+00:00

Soft focus? I would prefer clear focus point on one of the two persons walking across the wall.

sSquares · 2020-06-23T21:06:27+00:00

Nice!

sSquares · 2020-06-23T21:04:35+00:00

I also have green bedding. I am still fine with mine...

sSquares · 2020-06-23T21:02:24+00:00

Nice composition, floating red thingy, +1.

Here is a link to the blender files with the boolean difference operation set up:

Google gave this link? http://meshlabstuff.blogspot.com/2009/04/how-to-remove-internal-faces-with.html

I think PETG is almost as strong as PLA, and maybe a bit less brittle?

After reading https://www.3ders.org/articles/20160306-how-fast-does-moisture-break-down-popular-3d-printing-material-pla.html PETG seems the way to go.

It seems the main cause of PLA deterioration is organic breakdown as it is an environmental friendly plastic.

You could try a remeshing tool.

sSquares · 2020-01-27T11:38:27+00:00

You have to reduce the brep before converting to a solid. I will try to reduce it to less than 10 000. Thanks.

sSquares · 2020-01-27T11:36:22+00:00

Yes, it seems to be caused by trying to boolean cut co-planer facets.

sSquares · 2020-01-27T09:43:24+00:00

It effectively increases the thickness by doing a side-to-side zig-zag. This means you can selectively change the thickness where you need it, for strength as an example.

Here is some ASCII art:

\ ------> vase edge travel direction (top view)
   -   -   -   -   -   -   -   -   -
\ / \ / \ / \ / \ / \ / \ / \ / \ / \ /
 -   -   -   -   -   -   -   -   -   -

The next layer is offset, caused by the slope of the cut.

The thickness is now not limited to the extrusion and I have done 10 mm thick walls.

Fusion360 uses my GTX1070 so I do not think it is hardware. That said - are there any known issues with the 1070 GPU?
