When I was in college and 3D printers were taking off after becoming more economical, I really wanted to go into 3D food printing. I did chemical engineering hoping some day that would be possible and I could invent a Star Trek replicator for food.

My man, I share your dream as well we need to base it on soy, soy has many properties that we will find in real meat, and best of all it takes flavor very well.. applying this to a 3d printer with a combination of meat glue, and some food dye we can make it a reality... yes it's gonna take time but, it will work

Thanks for the video! I just grew some interest in 3D printing and your video served as a great introduction!

Hi, which method is possible to mix PLA/PHA and natural fibers to mix and use 3D printing ?

Super fascinating stuff, thanks for this! I'm a pre-hobbyist wanting to shop around for 3D printers to use in combination with horticulture [seed starting probably]. Such cool technologies, my favorites are DLP + LCD

Hi, I have a question. Is there any possibility for the 3d printer to print on an exterior surface? I mean, for example, the extrusion base printer, could it print on a different surface area (table surface, board ...etc.)

Yes you could you would just have to figure out your surface adhesion for the initial layer.

Hi there. I’m fantastically ignorant when it comes to 3-D printing and I’m trying to learn as much as I can through excellent videos like this. I would like to know what type of 3-D printer would be best for making plastic molds of car and truck accessories that will be samples for future mass-produced items probably in metal. Some of these accessories are custom-made cell phone and hooks, but others would be custom-made light bars that would be long as in the width of a light truck. Do you have a recommendation as to which 3-D would do the job of small items as well as items that are 60 to 70 inches wide?

nice...

If your just getting into it. Id get. Ender 3 for $170. Its a great printer to see if your into 3D printing. Can print very nice prints. And if you want something bigger or nicer later. You can resell the ender for most your $ back. Considering its not to expensive at $170 to start with.

I have now got idea

I'm sorry if this critique is harsh, but... I teach Additive Manufacturing at a well-known community college in Silicon Valley. I've been working and consulting in 3D Printing for 10 years. That said... this is a terrible way to classify or group types of 3D printing processes. It takes a 'bottoms-up' approach to the taxonomy of printing processes. By this, I mean that it essentially says, let's look at the printers themselves and see what the salient characteristics of them are, and group them by what they have in common. If you do this, you'll make a distinction between, say, DLP and LCD/MLCD. Why? Because they have different hardware for projecting an image onto a pool of resin. In reality, they are the same process, just using different hardware to accomplish the same thing: DLP printers use a DLP Chip and projection optics for forming the image, while LCD uses an LCD display for a near-field image projection. But, once the image is formed on the transparent window at the bottom of the resin tray, what's happening in the process is identical. A much better taxonomy is to go ‘top down,’ starting with the ASTM standard seven categories of 3D printing processes. The key word here is PROCESS. By focusing on what’s common in the process itself rather than the printer, we can get a much better basic understanding of how the various processes work. We can then take a look at exemplars of processes in each category. For example, the ASTM process category POWDER BED FUSION includes the processes called Selective Laser Sintering (SLS), Selective Laser Melting (SLM) - which, unfortunately, is still well-known by the misnomer DMLS - and MultiJet Fusion (MJF). So, what’s the problem with classifying these as the three types of Powder-Based printers? The answer: printers based on the ASTM process category known as Binder Jetting are also powder-based. Mr. Rainmaker 3D either isn’t aware of this category of printers, or ignores it because it’s really an industrial process and his target audience is the hobbyist. But, in presenting the field of 3D printers rather than processes, his information is at best incomplete and most likely confusing to anyone who digs a little deeper and comes across Binder Jetting printers. Finally, even though I’ve watched only about the first 3 minutes, I’ve seen several errors already in his information. For starters, the video clip on metal Material Extrusion printing beginning at 2:13 shows a Markforged Metal X printer. He wrongly identifies it as a Desktop Metal video; both DM and Markforged would be none too pleased to see this confusion/mis-representation. A second error: right at the outset when he presents his list of the types of 3D printers (0:40), he mis-classifies one, which is a pretty significant mistake. Laser Metal Deposition (LMD) is most definitely NOT an extrusion-based process; it is a Directed Energy Deposition process, which uses an entirely different physical approach and hardware. He is probably confused about the difference between LMD and Desktop Metal’s branded name for their metal extrusion process (which, again, his video does NOT show); DM calls it Bound Metal Deposition (BMD). You can see how this would be a simple mistake, but at the end of the day, his information is just… wrong. [Edit: I just sat through the rest of the video. What he shows as "LMD" - a very short clip of Relativity Space 3D printing their rocket - is indeed LMD. But LMD is NOT an extrusion process. Clearly, Mr. Rainmaker is ignorant of the process; if he knew anything about it, the first thing he'd know is that the metal is not being extruded!] I’m an educator in 3D Printing. When I see KZread videos of purported ‘experts’ wrongly explaining aspects of the rich and exciting world of 3DP, well… it just makes me cringe. Yes, I’ve taken him to task. Because no, he has not done his homework. As they say Abe Lincoln (or was it Mark Twain?) once said: “Better to remain silent and be thought a fool than to speak out and remove all doubt.” Poorly-researched videos such as this do not serve Mr. Rainmaker well in his quest to solidify his reputation as an expert and educator in 3D Printing. Au contraire…

I have to say this is the most thorough critique I have received to date, here is a trophy 🏆 With that said I can appreciate that you understand this topic well, better than most. As a teacher you can understand that you have to be able to reach your audience. You are correct there are mistakes in this video, I could of done better. With that said this is intended to help provide a general overview to someone who is totally new to 3D printing. Just as when we teach about the atom what is presented in a textbook is nowhere close to reality, but we must start somewhere in order to illustrate the concept at a level the audience can understand. I will continue to work and improve my own understanding as well as my ability to make content in the future. Thank you for your detailed critique.

Thank you for the great video. Very informative. I suggest you to use very small microphone, the big one does not look cool.

It seems, the volumetric process is actually the only one that _literally_ is "3D Printing". All other processes repeat a 2D printing process alongside the z-axis (or repeat a 1D printing process along 2 other axis). Of course you create 3D objects with all process, I'm aware of that.

*"Wanna print a brain?"*

So any printer that's has any real use is unthinkably expensive and is basically only for large manufacturing companies.. While all the 'desktop' 3D printers within reasonable budget are basically just gimmicks to print useless table-top figurines... There are so many 3D printing youtube channels, making videos like "OMG best printers in 2021!!!11" yet not one of them actually makes anything that has any real-world use with these printers which leads me to believe this technology (outside of large industrial machines) is largely a useless gimmick.

That is completely incorrect. You have different levels of printers. You have hobby printers that fall into the cheap category you speak of, and inside that category there are plenty of cheap printers capable of printing objects that people can actually use. People use them for art and for making small replacement parts. Just like with anything you have to do your research and find what machines are good and which aren’t. You can get a machine that is useless, or you can get a machine that works and slowly upgrade it or fix it up to be more precise. You have to be realistic and know what you’re getting and what it can do.

Unless you're printing metal, fdm should get the job done (or dlp if you can handle the chemicals properly). There are so much more to the expertise in understanding the engineering process that's not covered in this video. I took a course in 3D printing in university to know these stuff too lolz. But yea, I don't know about the quality of 3d printers at like $500 range. The one my university use costs like $5k and is still limited in many ways. That's not to say FDM prints are useless though. If you design and engineer your 3d model properly, it should be usable. I replaced a broken plastic part of my electric fan. I've seen other students created hardwares that can withstand limited force like bolts, screws, joints, etc. It also depends on the material of the print too, of course. Cheap fragile plastic will get you cheap prints.
