Nice reunion / gentle restart of @hackwimbledon today. We've not met in a long time; we lost our friend @codepope unexpectedly, earlier in the year. Making plans for 2026.
Hey wait, that was an unintentional pun! #maker đ ď¸

@hackwimbledon ... it felt weird to sit in DJ's "spot" at the front, and be doing the event hosting (rather than being a heckler!), but it was great to have the core group back together. It is clear there's a desire to keep our #maker group together, sharing knowledge, ideas, and solutions with one another.
Wimbletech - our host space and spiritual home - continues to be a very generous and welcoming environment.

Pause Print, Add Hardware, and Enjoy Strength
3D Printing is great, but it is pretty much the worst way to make any given partâ except that every other technique you could use to make that part is too slow and/or expensive, making the 3D print the best option. If only the prints were stiffer, stronger, more durable! [JanTech Engineering] feels your plight and has been hacking away with the M601 command to try embedding different sorts of hardware into his prints for up to 10x greater strength, as seen in the video embedded below.
Itâs kind of a no-brainer, isnât it? If the plastic is the weak point, maybe we could reinforce the plastic. Most concrete you see these days has rebar in it, and fiber-reinforced plastic is the only way most people will use resin for structural applications. So, how about FDM? Our printers have that handy M601 âpause printâ command built in. By creatively building voids into your parts that you can add stronger materials, you get the best of all possible worlds: the exact 3D printed shape you wanted, plus the stiffness of, say, a pulltruded carbon-fiber rod.
[JanTech] examines several possible inserts, including the aforementioned carbon rods. He takes a second look at urethane foam, which we recently examined, and compares it with less-crushable sand, which might be a good choice when strength-to-weight isnât an issue. He doesnât try concrete mix, but weâve seen that before, too. Various metal shapes are suggested â there are all sorts of brackets and bolts and baubles that can fit into your prints depending on their size â but the carbon rods do come out ahead on strength-to-weight, to nobodyâs surprise.
You could do a forged carbon part with a printed mold to get that carbon stiffness, sure, but thatâs more work, and youâve got to handle epoxy resins that some of us have become sensitized to. Carbon rods and tubes are cheap and safer to work with, though be careful cutting them.
Finally, he tries machining custom metal insets with his CNC machine. Itâs an interesting technique thatâs hugely customizable, but it does require you to have a decent CNC available, and, at that point, you might want to just machine the part. Still, itâs an interesting hybrid technique we havenât seen before.
Shoving stuff into 3D-printed plastic to make it a better composite object is a great idea and a time-honored tradition. What do you put into your prints? Weâd love to know, and so would [Jan]. Leave a comment and let us know.
