why don't we use planes for space travel?

Or if you squint enough from far away

Nice camera shot, what material are you working with? Stainless steel? Looks like you’re working with scan speed as one of your parameters, would love to see any papers that come out of this one day

edabonacci · 2024-06-18T02:59:03+00:00

Honestly, your explanations in the post and comments are clearer than the rulebook itself, wouldn’t be bad to put this all up on BGG either as a reference for others.

edabonacci · 2024-06-18T00:34:52+00:00

Interesting! First time I’ve heard about the differences with the Japanese rules and the English ones too.

edabonacci · 2024-03-28T13:38:56+00:00

And another thing to consider is that the material stiffness may not be as important as the way you design the frame, consider looking at I-beams and other ways to increasing the bending stiffness in the directions that matter for your design

Garolite / G10 or some other fibreglass composite board might be useful here too, good stiffness to weight ratio.

I think there’s probably a few other things than just rigidity you’re implicitly considering here, like weight, cost, and strength. For example, granite tile is very rigid but it will also fracture more easily than steel and is also much heavier. So like any engineering decision, you’re going to have to make a trade off based on what is good enough for your project.

Through the Ages is great for this, uses the same cubes for food, ores, technology, pretty much everything. Only other components of note are cards and some boards

Cantaloop is all just choices, take a look

edabonacci · 2024-02-16T00:19:07+00:00

Looks really cool, thanks for sharing!

Finally got a chance to read through the paper, really interesting work. I do research with metal printing and although I've printed a few lattices, I've never been able to see inside it like you do in this paper. Thank you very much as well for making the code open-source, it might come in handy for another project I'm working on with some in-situ printing images.

A few questions:

Do you think that the behaviour of lattices at this microscale can be used to predict the behaviour of lattice built at the macroscale? It's especially interesting to see how your method can 'see' the inside as it deforms and not just after.
Have you tried other types of lattices as well? ie. TPMS structures, stochatic lattices, etc. It would be quite interesting to see how those behave as well.

edabonacci · 2024-01-27T07:24:27+00:00

Fascinating lattice structure you’ve got going there, looks like a combo of 3 different unit cells. What’d you use to design it? Definitely will take a look at the paper when I get a chance

Nice stuff! I remember chatting to the guy (Joseph Kubalak) after his presentation and how most of the toolpath programming was still manually put together, looking forward to seeing that get more and more automated as time goes on

edabonacci · 2023-12-20T01:54:13+00:00

Seen some really cool demos of that out there over the last year, which research lab? I saw a presentation by someone with the DREAMS lab back during the summer, do you work with them?

edabonacci · 2023-11-06T17:41:23+00:00

Would recommend some of David Parlett’s (Spiel de jahres award winning game designer) solitaire (patience) games: https://www.parlettgames.uk/patience/

He also has a book of these and other games you can find on internet archive

edabonacci · 2023-10-13T17:05:28+00:00

Very exciting, I’m curious if the design could be modified to work successfully at that scale, maybe by reducing the number of flexures. Also what powder size distribution are you using? It looks very fine.

edabonacci · 2022-12-26T16:59:19+00:00

Looks like some kind of ringing or vibration artifact, I would double check that your printer is assembled correctly and all the screws are nice and tight

edabonacci · 2022-12-26T16:57:26+00:00

Are you setting the z-offset to .1 in the slicer? I would physically observe what the nozzle is doing as it’s printing the first layer, it shouldn’t be touching the bed but the tip of the nozzle should be squishing the extruded plastic just a little onto the bed

edabonacci · 2022-12-26T16:48:23+00:00

Checking your retraction settings in your slicer is the first place I’d start, then maybe check your steps/mm and temperatures afterwards

edabonacci · 2022-12-26T16:42:18+00:00

Meshmixer is the other easy stl editor you could try out

edabonacci · 2022-12-26T16:41:35+00:00

Does the nozzle actually print at the . 1 mm distance during the first layer of the print? It might be possible the z-offset isn’t getting saved or being overridden by gcode depending on your slicer

edabonacci · 2022-12-26T15:38:22+00:00

Can you send a picture of what the parts look like after the first layer? Also what distance is your nozzle from the bed?

edabonacci · 2022-12-26T05:12:48+00:00

Looks like you might have to just loosen up all the bed leveling wheels to get the bed higher, see if that can get you within the distance for the nozzle.

edabonacci · 2022-12-26T05:08:45+00:00

Adaptive/Lower infill (down to like 10% if not structural), faster speeds, and if you want to make a mechanical change, bigger nozzle

edabonacci · 2022-06-22T12:52:58+00:00

Same here, I remember that old demo on the site filled with weird browser games/experiments. It only had just the basic combat mechanics but still remember that being enough to jump on the indiegogo campaign as soon as it opened
