Underwater 3D printing could transform maritime construction | Cornell Chronicle
An interdisciplinary collaboration has developed a way to 3D-print concrete underwater – a technique that could transform on-site maritime construction and the repair of critical infrastructure.

Our tree topper broke, but now I can print a new one!
Honestly really amazing what you can do with 3D printing.
My former hometown of Vienna has had a lot of influence on it early in 3D printing history…

This was an interesting problem to work on (back in 2017): A visualization of a path planner for 3D printing (FDM) a single layer/mesh structure of a multi-layer textile. Two setups of the same path strategy which optimized for longest continuous sub-paths and minimum rapids (distance without filament extrusion) between sub-paths. The planner supported six strategies in total, incl. optimizing for straight sub-paths and minimum amounts of "recent" crossings (to allow filament to co…

Here’s so many technologies that are actually helpful and amazing and I’m exited about, here’s some more:
- e-paper
- health tracking that alerts to possible conditions
- safety features in vehicles
- new vaccines
- those soundboards for pets allowing them to form sentences
- 3D printing
- LED lights
- new, less dangerous battery technologies
And so much more

I'm finally trying printing with Spiderflex (77-82A shore) filament. The print speeds remind me of my first 3d printer. Two tiny parts totaling under 3g took about an hour, printing with a maximum speed of 10mm/s. But having really flexible TPE is really handy; there's really no reasonable alternative!
Now I have new feet for my KX3, and honestly they might be better than the originals (sorry Elecraft!) They are at least as grippy on the table surface, and they are a closer fit on the …

Just swapped the 0.4mm nozzle of my 3D-Printer for a 0.2mm Nozzle. The level of detail and smoothness is stunning. Printing dust covers for USB A and C ports

CRAFT printing method makes affordable, realistic replicas as structurally complex as a human hand
Researchers have developed a new method for 3D printing objects with very different properties, including levels of hardness and transparency, on a pixel-by-pixel basis while using commonly available materials and inexpensive 3D printers. The method, described in the journal Science by researchers from The University of Texas at Austin, Sandia National Laboratories and two other national laboratories, could lend itself to the creation of realistic models of body parts for medical students to pr…

3D printing researchers develop fast-curing, environmentally friendly concrete substitute
Researchers at Oregon State University have developed a quick-setting, environmentally friendly alternative to concrete they hope can one day be used to rapidly 3D print homes and infrastructure.

Over the past couple weeks, I've been designing a spool with some particular features in #FreeCAD, encompassing 6 parts to 3d-print. I've been manually re-orienting them when I print them.
Now that it's working, I realized that I could use the FreeCAD Assembly workbench to create a good packing of the parts in the right orientation for printing, saving anyone else who wants to prin…

I've really enjoyed hearing where we are on 3D-printed rib-ticklers sooo...
MAST #3DPrintingGeeks!
Tell me the wildest new thing in your area that will make me go WOW!
Is it speed? Materials? Colours?
Also, when do you think 3D printing will go truly mass-market? It feels like you still need a load of patience / expertise?

Added the 2k display (the original one I got was defective) to the #Framework 13 laptop. It's matte, so not as shiny as OEM, worth the rounded corners, IMO.
Replaced the cracked bezel too - mulling on 3D printing, gluing, and soldering, but that has me tired just thinking about it, lol.

Time to harness the sun! ☀️🛰️

Woke up at 5am and got an idea to fix a 3D print that didn't quite fit. Started the printer and it might be done in time for when I have to leave the house. No, I'm not a addicted to tech nerdery #3Dprint #3Dprinting

Laser-assisted 3D printing can fabricate free-standing thermoset-based electronics in seconds
Thermosets, such as epoxy and silicon rubbers, are a class of polymer (i.e., plastic) materials that harden permanently when they undergo a specific chemical reaction, known as "crosslinking." These materials are highly durable, heat-resistant with excellent electrical insulation in various applications such as in adhesives, coatings, and automotive parts.

How astronauts will fix their gear using thin air
Additive manufacturing, more commonly known as 3D printing, will be an absolutely critical technology for any long-term settlement on another world. Its ability to take a generic input, such as plastic strips or metal powder, and turn it into any shape of tool an astronaut will need is an absolute game changer. But the chemistry behind these technologies is complicated, and their applications are extremely varied, ranging from creating bricks for settlements to plastics for everything from cups…
