1508 3D Printing - A History And A Competition

[charlesurrea]

We used to make armor by laying bead on bead arc welds.
I refer to mine as CNC glue guns.

Good bit of history, I'm a trekkie too. Have you noticed a drop in voltage of the rain generators? I have made several versions using dripping water and they start out with some good generation and then drop off to less than a tenth of a volt. Just wondering if anyone else has experienced this. And, Thank you for hosting these competitions!! Great Fun.

Candle making by dipping a wick in molten wax comes to mind.

Woof woof... this old dog better start shaking a leg... or two!! I have to say... I've been dithering far too long... so, build I must... Thanks for the reminder and the history session!!😁😁

Exactly and why I was so intertested when I discovered them back when buying one was the only info I had from places like 3Dsystems (inkjet style wax printer was the cheapest)
and is what I have been imagining all sorts of way sto use any scientific info I have come across my whole life with the goal to add to creating such a device, (mostly because star ships and travel already had my interest, and I had figured way back then when I was like 7 that it would even be remotely possible both to do the construction and maintain supplies in journey too, by breaking down everything when it is thrown away, to recycle the atoms back into making something new needed ! ) and now I am moving to where I will have more room to work even futher with all the equipment I have accumulated to try and get to that gen 0 version, before using it to print out the (and process materials for the first time directly to use in printing) for version 1.0 :)

I would argue that the first 3D printers were the icing bag with tips and the soft serve ice cream machine :)

[KelkieFPV]

the 3d printing future gives me goose bumps . am also a trecky love the comedy cartoon version and picard is great at moment

[stevetobias]

I love Star Trek also, so much tech was on tv before it became real life tech. Laser's are one I think

[BradKarthauser]

Hi Robert, I suggest a poll. Will the first 3-d printed meal taste like: A. Cardboard; B. Chicken, C. Polypropylene

[dmaker]

Cool Rob! I love 3 D printing. I'm actually looking into 3 D printing a battery. That sounds like fun Rob! Cheers mate.

[stevebeynon]

On a different topic. Have you thought of building a VAWT power fence to power a home with a fenced in yard

[PhilWaud]

Doesnt seem right that you miss out the reprap project, surely that was instrumental in getting printers onto desks?

[D_Printing]

SLA still has an issue with Toxic materials used, so far as I know

[simonwatson]

Hey Rob, you're a clever bloke. Could you create a plastic grinder (old 3d prints/ other plastics) which has a built in extruder, in order to make 3d printing filament?? The only reason why I don't want a 3d printer, is because I don't want add to the plastic scrap, that ultimately ends up in the sea. Although, a metal 3d printer, made from a MIG welder, could be possible, and probably more useful??

[edwardmyers]

A friend got me a 3D printer but the only problem is the edit software. I'm use to mess with AutoCAD and Prodesign back in the 80s
even smartCAD PC design and that took me a while to learn to use them. Using a Free 3D editor and figuring out how to use it has
come some what a pain and it's been years since I've mess with my old DOS CAD programs.

one piece of fiction with 3 books total, I have to recommend to everyone that they try out is the Starrigger trilogy by John DeChancie (there are others named starrigger but they are NOT even close to this epic 3 book journey of "starrigger, Red limit freeway, and Paradox alley" a colorful chase across the cosmos in a twin hydrogen fusion reactor driven semi truck of massive proportions, *(worked it out to be about 1500 foot long and 100 foot wide or something) to meet the road builders through portals on planets, massive aquatic life forms converted to use as subs where the roadway has some how been sunken under an ocean, (to get to a portal on the other side of said ocean on that planet) potluck portals that no one has ever returned from all because people think he has a digital roadmap of the whole universe's skyway that connects the planets in the novels (there are also weapons in it toward the end that are sentient and have only one purpose when fired, destroy their target and will even consume energy as well as breaking down matter to fuel them so powered shields are a specialty they are designed to defeat LOL which I love being called Tasmanian devil, in the enigmatic 56 chevy or what ever old time car look alike skyway worthy vehicle (air tight as some stretches are on places like our moon, ) being driven by a kid who claims he was abducted by aliens and when he came to he was in the future on the skyway (far from his mid 1960s home sadly) and just somehow knew how to navigate and use the necessary functions of that car, ect,

Seriously if they had made this with the love and care that Starwars got, the same time as starwars, I suspect we would not have Starwars as the opposing juggernaugt to Star Trek, it would have been this show, AND I am certain there is evidence that story line plot points and entities were taken from this series for the last stargate universe TV show, as it was leading to the gateway builders also teleportation tech though not as sleek and dangerous as the skyway's portals and massive spinning faster than light, dense as black holes cylinders along the sides of the road that kept the portals in the books open all the time, (and designed to avoid time shenanigans like arriving before you left but are capable possibly if misused while avoiding being sucked in and destroyed LOL

[edwardmyers]

Thanks for the info. Back in the 90s I design a pets water dish that would not spill water even if upside down. I have a prototype but would
like to make a better version. I look into making a 3D scanner using a Pi but there is another guy in your country talked about some software
which you take a bunch of pictures around whatever thing and it puts it together. Again You guy are great just love all the ways you come
up with.

[ThomasAndersonbsf]

I have to wonder if the first human intentionally created process that was 3D printing (not cell growth because we don't do it with conscious purpose, I am talking invention type stuff) was basically clay work where you are adding material together to make something instead of taking away from it (additive manufacturing where the hands are the tool that adds and water is the sticky component to bond while the solids allow it to retain it's shape, and even you even have slumping concerns and all sorts of stuff like we do now when printing with overhangs that are in air such as fused filament process) just something to make the mind boggle by looking at the earliest thing we can think of and go from there, technically the people moving the stuff to the site and placing it were the 3D printing mechanism for 3D printing the pyramids LOL

[jeffreywolsieffer]

while the Printers themselves are not all That new to us Old Schoolers, I got our grandkids interested in "3D-Pen's" a few years ago.
. a company called "SkyWriter3D" came-up with A Kids Version - for building 3D Objects w/o A Computer.
. . . what caught Their Attention was When either They or I would *crash* our RC things and how quickly I could repair them.!
- from Doll House Tables & Stools to constructing those Doll House's Fences for Barbie Horse Farms, Sir Rob's Lego's fail by comparison.

[islandsedition]

If that new Star Trek style printer can make food and medicine, we may never need to make anything else ever again, unless it is for fun.... (Or sourcing the materials needed for the printer!)
