**The World of 3D Printing: From Chocolate to Chips**

In the world of 3D printing, creators are constantly pushing the boundaries of what is possible. For some, it's all about crafting intricate models and objects with precision. But for others, like our host, 3D printing has become a means of creating delicious treats that were previously unimaginable.

One of the most interesting examples of this is the creation of chocolate structures using a 3D printer. The process involves infilling a mold with molten chocolate, layer by layer, to create complex shapes and designs. By adjusting the amount of infill - or empty space within the structure - the taste and texture of the finished product can be significantly altered. "You just have zero top layers," explains our host, "and you can generate infill for shapes." This innovative approach has led to the creation of chocolate structures that are not only visually stunning but also tantalizingly delicious.

But 3D printing isn't limited to sweets. The same technology is being used to create functional objects, like computer parts. In this case, a company called Coco Pressto made a groundbreaking achievement by creating a 3D printed boat using high-quality materials and advanced printing techniques. While the build quality of the final product was not perfect, the team behind it learned invaluable lessons about shipping and reliability.

**A Closer Look at Intel and AMD Chips**

In a surprising departure from the usual discussion around 3D printing, our host turned their attention to a more unusual topic: who makes tastier chips - Intel or AMD? The debate may seem frivolous on the surface, but as our host demonstrated, even the most mundane objects can be elevated by innovative design and advanced manufacturing techniques.

The taste test was a resounding success, with one of the chips being deemed "surprisingly fast" despite its resemblance to a filament printer. It's clear that the manufacturer, Intel, has made some significant improvements in their technology, resulting in a product that is not only faster but also more efficient than its AMD counterpart.

**The Power of Customization**

One of the most exciting aspects of 3D printing is the ability to create custom objects that cater to individual needs and preferences. For confectioners, this means being able to craft elaborate chocolate structures with ease. "I could see cake makers or other confectioners making an absolutely killing" using a 3D printer, our host exclaimed.

**Staying Private Online**

As we explored the world of 3D printing, it's easy to forget about the importance of online privacy and security. With the rise of digital technologies, more than ever before, it's essential to take steps to protect ourselves from prying eyes and hackers. Our host recommended using a VPN (Virtual Private Network) like Private Internet Access (PIA), which offers reliable service, no bandwidth caps, and configurable encryption.

By combining this with private browsing best practices, individuals can enjoy the benefits of online freedom while minimizing their exposure to surveillance. With PIA, users can connect up to 10 devices at once and take advantage of a dedicated IP option that provides an extra layer of security.

**The Future of 3D Printing**

As we look to the future, one exciting development is the creation of a tool-changing 3D printer designed specifically for building entirely 3D printed computer cases. This project promises to be a game-changer in the world of maker culture and will undoubtedly keep our readers engaged.

"WEBVTTKind: captionsLanguage: en- So what youdo today at work honey?- I did something.It involved white goo in my mouth.What do you get whenyou combine a 3D printerwith a mini fridge and someconfectionary know-how?I'll tell you what you get.The Cocoa Press,a chocolate 3D printerthat may just be the most delicious thingthat we have ever reviewed.And also one of the most challengingbecause even under ideal conditionschocolate is not easy to work withandextruding it through a tiny nozzlewithout clogging or other issues?Not exactly ideal conditions.But the good news is we learned a lotand we had a ton of fun usingit and eating our mistakes.Hmm.That's good.What's also good is our sponsor GlassWire.Are you lagging out while gaming?Use GlassWire to see what appsare wasting your bandwidthand causing your games to lag.Get 25% off today, using code'Linus' at the link below.(lively electronic music)Damn, that is good.Okay, all right.I'll put this down for now.3D printing,it's all ready no walk in the parkand that's with plasticsone wrong parameter,andyou're left with a failed printand a bird's nest of goo,which is probably the biggestadvantage of the Cocoa Pressbecause with this success or failurethey both taste equally sweet.But the road to getting our handson our first chocolateprinter, hasn't been easy.The first Cocoa Press that got sent to usgot absolutely demolished in shipping.And while the replacement machine herecame in much better shape,it did still get slightlyborked in transport.So, I got to put that right out front,our experience isn't the complete picturebut we'll give you a bitmore detail on that later,first let's talk about thewho, and maybe more importantlythe why.(laughter)The creator of the CocoaPress, Evan Weinsteinstarted printing withedible materials in 2014by modifying a plastic 3D printerwith a custom syringe extruderand a bunch of supporting modsto deal with the difficultthermal control problemsthat chocolate presents.Early versions of theprinter used air pressureover a syringe of melted chocolate,which was then cooled by asubambient water cooling loopwith a Peltier element.That is so cool,and not that differentfrom the water-cooled chairvideo that we did a while agoV1 wasn't the end however,and the cocoa press eventuallybecame this capstoneproject at Penn State U.With some help from the Pennovation centera startup incubator, that'sattached to the schooland a small team of materialscientists and maker nerds,he eventually created whatstands before us today.Version four-ish.Now Colin's been hands-onwith the Cocoa Pressfor about a week now and as you can see,some of our results are good, but others,well, we have onesthat look quite literally like (bleep)But we're still reallybullish on the device.So, let's take a closer look at it.It comes with presetsfor the different kindsof chocolate that you might want to useand you dial them in up herewith this touchscreen panel.You can load a full-size SDcard into the right up herewith your print files,and if we open up thedouble pane glass door,we,wait who this stuff in here?lttstore.com,right.Inside, we find a veryunusual print chamber.For starters, notice the wallto wall, to ceiling to floorstainless steeland complete lack of exposed fasteners.This is to facilitatecleaning for food safety.Cool, right?Almost as cool, actually not even closeas the star of the show, the extruder.Where this differs from theplastic filament fed machinesthat we use frequently is under the cover.Here, we've got a steppermotor hooked up to a syringewith this stainless steelchamber wrapped in heating pads.Inside that chamber, youplace these pre-temperedand shaped chocolate slugs like sowith the inner cylinderlocking into the headon these two locking lugs.There are two heater zones,one for the body and one for the nozzle.One cool note hereis that there's nothingproprietary about the refills.You could put in icing, cheesewhiz, your own chocolate,whatever you want.But for the purposes of this videoand limiting our variables,we'll be sticking to theincluded pre tempered chocolatewhich really is delicious by the way.Now that takes care of theCNC chocolate dispensingbutas for moving it around,that's done with a CoreXY motion system.CoreXY is just a fancy wayof laying out your motors and beltsthat gives a few performance improvementsover traditional Cartesian machines.In traditional Cartesian machines,one motor is coupled directlyto one axis of movement,but CoreXY is a fancier wayof laying out your motors and beltsthat gives a few performance improvements.So in CoreXY,the two motors both work togetherto produce motion in just one axis.So if we were to pull on just one belt,which you can see itactually moves diagonally,but get this.If we pull on both belts,let's see if I can get in here.There you go.We can just move along the Y-axis.As for the Z-axis, it's more traditional.It rides on two railswith a screw that's hidden behindthis stainless panel at the backor, well it's supposed to.Unfortunately, our bestguess is that the parts kitthat was stored inside theprinter during shippingmanaged to crack one of thebearing mounts in transit.Replacing it would have required an almostcomplete disassembly andreassembly of the printer.So, instead we pried back the sheet metaland epoxied the ever-lovingbejesus out of it.Since then it's held up finethanks to the auto bed leveling gridbut we do treat it gingerlyanyway, just to be safe.Now, since the versionthat we showed you in our earlier footage,Cocoa Press has ditchedthe refrigerated airstreamand instead uses a patent pending,vapor compression refrigeration systemto keep the entire build chamberat just the right temperature.And when I say just the right temperature,I mean exactly.The difference betweenchocolate flowing too quickly,and it freezing insidethe nozzle causing a jamis just a few tenths of a degree Celsius.And the thermal problem that is thus,if you overheat the chocolateor heat it up too fast.you ruin the temperor the crystal structurewithin the chocolate.And that's really importantbecause maintaining thatis what gives chocolatea nice surface finish and a crisp,snap when it's broken.Overheating can also causethe cocoa fats to separateand create bloom or pockets of faton the surface of the chocolate.They're not harmfulbut they're not exactly appetizing.On the other hand,if it's too cold, well,it's not gonna flow, right?And the same goes for the atmospherethat it's being printed in.Too hot, the chocolate won't solidify.Too cold and it'll freezeas it's coming out the end of the nozzle.Now, after our first few test prints,it was pretty clearthat something wasn't working as intendedand after solving the aforementionedbuild platform issues,we hit an even bigger snag.The compressor for thechamber refrigeration systemis not working as intended.It caused temperaturespikes that turn our printsinto gooey messes,like this one.Can still taste good, but itwasn't exactly the best wayfor us to show off theunit's capabilities.So they hackily addressed itwith a custom firmware thatyour working unit won't need.And finally, we were off to the races,or so we thought.Chocolate printing is,I can't mince words here,really hard.So Colin spent days fudgingthe temperature up and down,a 10th of a degree,haha, pun intended by the way.Then waiting half an hourfor those changes to propagateto the rest of the chocolateand then testing and retestingand then we'd get a good printand then everything wouldgo out the window again.And the road was long and delicious,butvery frustrating.Both our milk and dark chocolateproved to be unreliabledue to the handicappedstate of our Cocoa Press.White chocolate, however, canbe printed at 18 to 20 degreesandactually turned out pretty well.But I'll let the resultsspeak for themselves.This is pretty impressive.- Yeah.- There's still some errors.- Little errors.So this was done in vase mode.So one of the problems we hadwas the stepper driver for the Z-axiswas skipping or adding some stepsand you could see things got elongated.So, by just having itrise slowly in a spiral,we kind of mitigated thatand you can see where there's feed issues,where there's a pocket, thechocolate wasn't homogeneous.And we ended up with little failures,but the rest the print went pretty good.- Pretty good.Even in milk chocolate,as long as we didn't go too high.- Yeah, as long as you stayed low.- That's a very recognizable LTT logo.That's freaking cool.Although I do have to say Colin,some of these I'm not convincedthat you ever 3D printed at all.It looks like all you everdid was turn a phallusinto another phallus.- You're not wrong.- It's not very transformative.- Yeah, and so I have acouple of samples here we can,so these are texture samples.These are actually literally just infillfrom a 3D printing slicer.You just, to have zero top layersand you can generate infill for shapes.- Oh, that's interesting.And then you take one that'smore completely filled.The taste is so much strongeron the one with less air pockets,even though to my monkey brainmy mouth is just full ofchocolate in both cases.- And that's something youcan't get any other way, right?You can create these inner structuresthat have different feelsand you're adding a newdimension to the chocolate,to the food.- The white chocolate in general, for mewhich isn't chocolate, by the way,white chocolate is a big scam.White chocolate is not my favorite,it's way too sweet for me.But what I found was withthe really big air pocketsit's actually palatable.- It mellows out, yeah.- I mean, I am more of a darkchocolate boy these days.- Those dick butts are dark chocolateand they came out okay.It was just a little difficult to extrude.- Right, cause we can't getthe temperature low enough.- Besides the frustrationit was really fun.- It still did managesome overhangs and stuff,so this is just a matter of,it needs to be working properly.- Yeah, like look at the pillars,you're printing in chocolate.It's horrible.But for what it is--- But wehad an issue with the--- With that in mind,come on.It's a chocolate fricking boat.- And now for the questionyou've all been waiting for,who makes tastier chips, Intel or AMD?See that David?They're Intel and AMD chips.Mhmm.Team blue, not bad.Mhmm, team red.I do like the taste of the core.- Hey, Linus.Eat a dick butt.It's surprisingly fast,obviously it's nothinglike a filament printer.- Well, I thinkthe big thing to note isthe nozzles 0.8 millimeterswhich is double the size ofwhat we have on the (murmurs).So our layer height islike half a millimeter,so it prints really fast.It's like each of the chipsI think is 11 minutes.- It just makes yousalivate just watching it.Now, as far as we know,this is the first Coco Pressto make it out into the wildand it's pretty clear that the team theredoes have some challenges to solve,particularly around shipping.But aside from thatone, the build quality,ease of use and the designitself are freaking awesome.I mean, it's a 3D printer in a fridge.And while at the end of the daywe weren't able to get reliableprints that were tallerthan say, a centimeter.The bones are all hereand they're really good.The extruder, which isby far the hardest partis excellent and reliable.And the motion system is beautifuland works exactly as intended.Now, at 10,000 US dollars,it won't be making its way intothe average maker's home labanytime soon.But once the wrinkles are ironed outI could see cake makersor other confectionersmaking an absolutely killing.We have custom toppers,fancy chocolate barsand that sort of thing.Once the wrinkles are worked outand they arrive in
