what is 3d printing

what is 3d printing


have you ever tried to wish something into existence well we live in a world where you can practically do that now we’re not talking about a magical genie we’re talking about 3d printers.
if you can think it chances are you can print it from 3d printed sushi to 3d printed organs here’s a rundown on how 3d printing works and how it’s changing our lives.
we demystify the technologies that are shaping the future. 3d printing is one of the most revolutionary technologies of the 21st century but what you might not realize is that there are tons of different 3d printing techniques out there.

overview of 3d printers 

let’s start with fpm which stands for fusion deposition modeling.
1. if you’ve seen a 3d printer in person then chances are it was an FTM printer so how does it work well functionally speaking an FTM printer works a lot like a hot glue gun that’s being operated by a robot solid material known as the filament goes in one end gets pushed through a hot nozzle that melts and is deposited in thin layers.
this happens over and over until a three-dimensional object emerges so in other words FDM 3d printing is basically 2d printing over and over again just each time a layer is completed the nozzle moves up just a little bit and the next layer is printed on top of it then there’s stereo lithography or SLA.
2. SLA basically uses light to grow objects out of a puddle. SLA machines work by shining ultraviolet lights into a pool photo reactive resin any resin struck by the light solidifies and forms a layer of the object you’re printing generally speaking these printers can create objects with far finer details than FDM.
3. the third variety of 3d printing is laser Center LS prints by flashing a high-powered laser over a bed of super fine powder fusing the particles together to form a thin solidified layer. the Machine then sweeps more powder over the top of that layer and repeats the process until the 3d object is complete.
this process isn’t common in consumer level 3d printers but on the industrial side it’s often used to create large durable objects out of metal in fact Space X uses this method to 3d print it’s super Draco rocket engine that’s definitely a tough act to fault but we’ve got one more on our list.
4. last but not least is a 3d printing technique known as Poly Jet think of this one has a mix of FDM and SLA Poly Jet machines squirt out tiny droplets of photo reactive resin onto a build surface and then immediately harden the resin with ultraviolet light this process is then repeated hundreds of times create objects from the bottom up.
the benefit of this method is that it’s crazy fast and super precise unfortunately most poly jet printers cost tens of thousands of dollars so they’re out of reach for people like you and me now that school is over let’s talk about the real world because 3d printing is used in almost every industry.
some common uses:
out there one awesome example is how 3d printing has completely changed the world of prosthetics. the thing about prosthetics is that every limb needs to be customized for each individual which makes prosthetics difficult to mass-produce with 3d printing though you can scan a person’s body and then 3d print a prospect that’s tailor-made to fit the unique geometry of their body.
there’s even a startup called print my leik that provides open source blueprints for prosthetics they allow others to create decorative prosthetic leg pieces that they can make as an extension of their own personalities no different than getting a tattoo sleeve or choosing clothes that capture some aspect of your personality.
we’re not only printing limbs now we’re 3d printing organs too. scientists have successfully 3d print eda mini human heart from stem cells this heart is partially functional and is used for pharmaceutical research.
there are a few challenges ahead and fully functional but the scientists are confident that in a few years this 3d printed heart will be able to function inside an animal or a human.
this technology could be used to create thousands of much-needed hearts for transplant surgeries enough about medicine
Nike is running away with 3d printing technology. the company recently introduced fly print a 3d printed textile upper for your sneakers it’s the first of its kind and it may bring about a new standard in performance running shoes because their 3d printed the shoes can be rapidly customized and produced for specific sports or specific athletes and the shoes can be prototyped 16 times faster than traditional shoe making methods.
3d printing is even making its way into the construction business these days it takes Extreme Home Make over a week to build a house but with 3d printers you can build one in a single day nonprofit startup icon invest in affordable housing solutions.
these houses are 800 square feet and cost less than five thousand dollars with 3d printing technology they’re able to provide housing and poor communities cheaper and quicker but what if you want a boat in the drive way of your 3d printed house well as Vince Vaughn would say it’s not a boat it’s a yacht naval architect Greg Marshall wants to start 3d printing super yachts.
when it comes to set design and prop making 3d printing allows studios to create custom props quicker and cheaper than traditional methods like us the animation studio behind movies like Cora line and Kubo and the two-streams uses 3d printing to create all the set pieces.
some analysts project that food production will need to be raised by fifty percent to maintain current levels how we currently produce food isn’t going to be able to keep up with that demand and 3d printed food maybe the additional production method.
we need to keep from going hungry. the really exciting part is that this is just the beginning. the earliest 3d printers were invented just a couple of decades ago and despite the fact that the technology is advanced and leaps and bounds in that time it’s still very much in its infancy.
today we’re printing organs and rocket engines in another decade or two there’s no telling what we might be able to create.
