Hello Crowdholders,
my name is Silvestr and I would like to use this platform to spread information about things I am interested in and hear your opinions.

The first theme I would like to share is a very dear hobby of mine and that is 3D printing. I will create a few of articles about different aspects of 3D printing and hopefully convince to consider this technology.


First of all, there are multiple of techniques to create a 3D object out of thin air. The most common 3D printers are based on FDM (Fused Deposition Modeling) technology, which is what this series of articles is going to be mostly focused on.

In order to explain the basics, I need to bring some analogy. Imagine a regular (2D) printer. It works by moving a paper up and down on one axis (let's call it Y axis) and then moving the ink left and right (X axis).

In layman's term, FDM works by melting almost wire-looking plastic, feeding it through a small nozzle and printing very thin vertical layers. The 'food' for FDM printers is called filament and the next article is going to be focused on all of the materials that filament can be made out of. A motor pushes filament through the heating block, which usually goes above 200°C, and then through a thin nozzle. The pushed material then gets deposited on the printing plate and the first layer of print is fairly similar to a regular printer. The printer moves the plate on Y axis and the nozzle on X axis. After finishing the layer, the nozzle raises a bit on third Z axis (hence the name 3D), by the value set as 'layer height'. Layer height can be as low as 0.05mm or as high as 0.6mm.

I like to compare FDM printers to a simple glue gun. Glue gun works by melting a glue tube and then pushing it thought a thick nozzle. If someone was to motorize the movement of it, it would essentially be a 3D printer.


FDM 3D printers are the cheapest with the price commonly ranging from $150 to $1000, but with the general unpredictibility of moving a molten plastic, there are other machines with better results. Potential dimensions of a model are however in tens of centimeters in every axis.

Another school of 3D printers is called SLA (Stereolithography) printing. Its niche is in printing via hardening resin. To do that, the printing plate is submerged upside down in a liquid and a laser, or now more commonly used display, shines a UV light on parts that should be hardened. The plate then lifts a bit and display hardens another layer of resin. This allows for a much smoother final print, however, you are limited to the nature of resin - it is fairly fragile. After all of the layers are hardened, you have to leave the print overnight in a special liquid to cure the resin. Other cons of SLA printing are:

  • Resin's smell when hardening is not very pleasant.
  • Dimensions are often limited to 15 cm, usually in one axis, other axis are less then 10 cm.
  • Price of printer starts at $400 and resin is not as cheap as FDM filament.

The final 3D printing techique I'd like to talk about is CNC (Computer Numerical Control). CNC is more industrial, precise and expensive than any other techniques mentioned. It works vice versa than previous ones, where you created a model out of nothing. With CNC, you start with a raw material, be it a piece of wood or metal and drill it with various drills of variable smoothing options. You literally have a cube of raw material and create a model by cutting away more and more of it. CNC can be as big as needed (meters are possible) and the cost goes well into thousands of dollars.


Questions for you, the community:

  • Do you own a 3D printer? If yes, what is the most curious thing you have printed with it? If no, have you seen this technology?
  • If you could create anything on the printer, what would you make?
  • Do you have some questions about 3D printing you would like to get answered?
  • Does this format of articles interests you?

That's all from me today and tune in next week where I'll discuss the materials FDM filament can be made out of.

Cheers,
Silvestr

i will say that 3D printing is really a very intersting and growing tech that will help the manufacturing industries a lot, and also making handy job easier since most parts can be made from the comfort of your home rather than lookng for it everwhere in the market. Nice sets of articles a good read for anyone interested in new and upcoming tech.

Thank you for this useful article, Silvestr.

1. I do not have a 3D printer. And I have never seen it work yet, but I've seen articles about this technology several times.
2. I want to make my home by 3D printer if I can make it.
3. Can you make small creatures? I wonder.
4. There is a clear interest in this article.

3d printing is a very good and upcoming way to make things easier for the community, will be looking forward to owning a machine, will like to build parts like phones part and also other electonices that i will use to fix things, parts that are usually made from rubber and plastics, because sometimes during working these parts tend to get destroyed.

I don't own a 3D printer and to be very honest you are the first person to give me an in-depth education on the various types of 3D techniques there are. Have I seen his technology? No. Not in real life. All I know about 3D is from my personal reading and the very few videos I've seen.

If I could create anything on the 3D printer, I would use it mostly to generate designs for the interior decorations of rooms. Actually, anything architecture. 

With questions, I have a few. Where do you see the 3D printing industry 10 years from now? Would it have a replacement? Do you see any other techniques emerging aside the three you've mentioned? Do you foresee the technology becoming cheaper or more expensive as time goes on? Are there any cryptocurrency projects concerned with the 3D industry? 

Finally, the format of articles really interests me because information is power. you don't know the opportunities that might pop up from something you don't even give much attention to.

I am quite interested in the development of 3D printers, but I have to admit, that I never dived deeper into the functioning.

Your post was a nice read and now I know some more about this technology.

I don't have 3D printer but I had watched it functioning on television.So I am aware of this technology

I would like to print or sample model of any machinery or machinery part. Due to which I will able to know how the finished product will look like

Will the cost of 3D printer will be lower in future and those it require licence to own it?

This type of article are very informative and also giving full information of the products

Thank you Silvestr for this interesting post. I am quite interested in the development of 3D printers, but I have to admit, that I never dived deeper into the functioning. Your post was a nice read and now I know some more about this technology. Is you will understand, I never owned one and also never have seen one live in action.

I think at the moment 3D printers are mostly used to quite cheaply build industrial prototypes, yes well and there are the enthusiasts who use them for fun. I can not see an actual usecase for the moment and I don't believe in the previsions, that 3D printers will be in every home and people will print out their stuff instead of having them mass produced in factories. I think you share this view as well, since you described the momentary available technologies quite well.

Looking forward to your post next week, lets see if I am wrong, assuming 3D printers can produce only low quality plastic stuff.

  • Do you own a 3D printer?

No, I don't have a 3D printer


  •  If no, have you seen this technology?

Yeah, I have seen it but the technology I saw was been developed by a group of student.


  • If you could create anything on the printer, what would you make?

Well, I don't know because the technology which the student developed didnt interest me at all as they created an ear which was really hard and it will very unreal. So I would make anything that looks more real like make a mask to have some fun around.


  • Do you have some questions about 3D printing you would like to get answered?

As in the movies, like Mission Impossible, that they create different stuff from the 3d printer is it possible if yes what kind of material did they use to make everything real like human skin?


  • Does this format of articles interests you?

Technology is the core of my heart and always amaze me, as did this article. 


Also why I liked this article is because it was short and to the point. 

2 weeks ago

You can print with rubber but I'm not sure how well it simulates real skin. Also, real skin is so complex that even with printing in multiple colors, it would look very 'flat'. You can print masks but not as well as in the movies :) Or maybe there is some military technology that allows this! But not available to public, no.

2 weeks ago

Well no can you tell me what is the main reason for the 3d printer?
I know that for some 3d design that we want to present to people as in offices is an example but how good is the 3d printer for household use.

1. No ido not have 3D printer. Yes i have oportunity to see how 3D printer can makee his own spare parts.

2.I think it will be usefull in medicine. maybe some parts for install in humans like femur, ribs, tibia, patela.

3. I have question: is it posibble to mix materials for printing?

4. yes i love new tehnology

2 weeks ago

Some bones probably could technically be created but I am not so sure with the long terms uses of them. With the bone marrow creating blood cells, I am not sure if there is a viable alternative to bones. But I am sure that this is only a matter of time and in a few years the technology will be here.

2 weeks ago

Also, you can mix colors of the material but not materials themselves. They don't usually share the same temperature they need to be printed with so they might not stick together. There are however already mixed materials with wood and plastic and others.

2 weeks ago

To the first questions, unfortunately, the answer is No. And neither have I seen it except on videos in youtube.

and if I could create anything on the 3D printer, well, presently I think experimenting with a little mid-finger ring to present to my fiance will do the magic.

Well, will it be economical to 3D print a durable house than to use a reinforced concrete for same project?

And as for the format of the article, well it looks natural and very informal. Makes me think that I am communicating with an actual human with feelings and not a machine..

Looking forward to reading more from you.

2 weeks ago

Hmmm, hard to say about the durability. For some small houses, I think it doesn't matter but some big need to have reinforcement by steel wires and those unfortunately cannot be printed.

All You Touch And All You See Is All Your Life Will Ever Be!

Amazing technology, we need to push for this technology to be priority in the world,

WHY ?

-Because its uses are limitless but most importantly "WE CAN SAVE THE WORLD",

HOW?

-Recycling plastic trash that we throw everyday in the world especially oceans, if we monetize this on grand scale, people will start collecting trash just to sell it at the same time cleaning the planet while reusing it in Medical industry, Engineering industry, Art industry, etc. 

1.No I don't and haven't owned 3D printer but I plan to invest in that world. I've seen the technology and its amazing...

2.I would make things that could serve humanity...

3.I have simple question 😊 How can I make money by investing in 3D printing ?

4.This format of article amazes me thank you !

 

2 weeks ago

Exactly! Having recyclable plastic and people using it over and over again for different purposes could help the planet.
Yes, you can definitely make money by 3D printing. You could make a model that people need and sell it. You can sell the final print or the model only, both totally possible.

Just going and buying property to later use a printer to build home would save so much human labor! Hopefully in the future this will be possible.

Like living creatures? Unfortunately, you cannot create living things and be a god basically :D But there is no limit to what models you can print.

I am a very hands on must know how why when details kinda person

No I unfortinutley do not have a 3d printer but sure know what they can produce..even tho I dont have a 3d printer I am definitely curious to want to make a miniature escape plaza and or model engines for learning them and the way the components all fit together and work in sequence to complete the task they were made for doing.. I have heard about and seen this technology start to grow and more interest showed with the printer...one question I have is...Does anything printed with a 3d printer does it in fact move and function or is it just a model basically like a small replica to use as a visual aid? Some things I would create are models to use in real world every day task or trials . First thing I wanna make though is a 3d spit wad shoot gun..

3 weeks ago

You can definitely print a movable parts straight from the printer... Or you can print multiple parts and put them together like a real thing! Because of this, I think it creates a safe enviroment to learn many things and if anything messes up, just print a new thing.
Good luck on your spit wad shotgun, haha!

Why would you print a cup? Such a unique answer!
While there are some materials with the addition of metals that share similar atributes with them, no, printing in metal is not available for a general customer. You can print in solid metal thanks to CNC. Or, you can 3D print a mold and cast the metal yourself.

  1. I do not own a 3d printer but I have had experience using one at my old job. My boss bought a 3d printer for us to play with and we all had fun making different things that interest us.
  2. I was able to print an ocorina from zelda and was actually able to play some of the songs with it. If I could print anything I would print a desktop computer case. I don't know if it would be good for transfering heat but you can't know until you try.
  3. One question that I have about 3d printing is how you can make money printing things with them. How does the legalities work of finding printing files online?
  4. This article was interesting to read and I would be interested in more.

3 weeks ago

That boss sounds nice!
I have the ocarina as well :) I'd be careful with the case, exactly because of the heat. Many materials soften from 60-100 Celsius.
Making money is quite simple. If you are creative and create your own models, you are the owner of them and can do whatever it is you want with them. Some people do this if they can't afford regular plastic molding or don't have skills with other techniques. If you print already made model by someone else, it is fine for your own use. Many of them are however shared under the Creative Commons licence and users can explicitly disallow commercial use of their models. Hope this clears it up!

I dont have a 3d printer but have read quite a lot about them ranging from small printers to those used in building sky scrappers, i wil say that i find the articles very interesting, because it showed more light on what i knew before. i will say that i will want to know more. i also like the fact that article is given in smal bit and not a very long material, i will say that this format is also very good since persons can get really boed from reading very long articles.

3 weeks ago

Yeah, I feel the same, having small bits of articles divided into different categories to keep readers engaged is the way to go. Those giant building printers basically work same as the FDM printers, but instead of pushing molten plastic through nozzle, it pushes concrete. Very interesting nevertheless.

There are a few companies that make custom prosthetics for children, which is absolutely amazing because some families might not afford a regular one and this helps them a lot.
Well, some custom made printers have basically limit of your own need but I think that the biggest printer you can commercially buy is 300x300x400mm.

A 3D printer is cool and gaining popularity. Although it's not my cup of tea but I do strongly agree that nowaday everything or everyone was looking for perfection especially art work. To use this 3D printer it echoes most on creativity which not all of us had. Anyway good headstart and looking forward to know and learn more about it

I know someone who does model trains and such and I always thought a 3d printer would be an excellent way to create models.  I have been watching how you can create plastic models for concrete stepping Stones and I assume you can do it for gargoyles and such so I find it fascinating.  I don't own or participate in a business where I use one though, I just enjoy watching the possibilities.

No but I've seen this technology my classmates assembled a 3d printer so pretty cool I want to make the little version of me.I want to ask what is the main heart of a 3d printer and how can achieve a great quality of artwork in 3d printer. Yes so cool and interesting.

3 weeks ago

If you're interested in printing a mini model of you, definitely check out photogrammetry ;)

I'm not sure if I understand the main heart question. There is a not too complex circuit and it follows the commands where should motors move in order to print the model (it basically says 'move left 8 cm','move up 5.3 cm' and so on

Having a great quality artwork is a bit hard. There are MANY factors (just to name a few of them: not correct printing temperature, tightness of different belts, moist material...) that influence the overall quality. But if you follow the guides on the internet, it's not hard to have amazing quality. Plus the 3D printing community is really helpful and friendly.

No, I don't own a 3D printer but I have had a school logo printed on one. I think the technology is amazing and there are lots of scopes to bring to life characters in stories for children and concepts in less visual subjects. 

I would definitely use it in education to enhance the learning skills and creativity of students; imagine their excitement knowing that printing their designs was a possibility in class. I would print crystal shapes in chemistry for their beauty

The article is good, a little technical but I guess that's required to give us a bit more insight into the project. I like the honesty in the pros and cons. I would like to follow this project and hope to learn more about 3D printing before buying one.

I am trying to make the articles a bit beginner friendly but hopefully next articles will bring something new to you.
Having a reusable plastic would be awesome. Printing often generates a waste made of support, unsuccessful prints and having the ability to grind it and reuse would make it extra cool. Some attempts are made for this but the results are not satisfactory yet. Impressive, but not the necessary quality.

I am excited about the future of all crypto currency.

I use to have a da vinci printer which broke every other week. I would print kayak fishing accessories. I would like to invest in a cnc machine. I would like to print or cut a compound bow. Do you think you'll get involved in construction 3d printing? I think everyone will own a 3d printer soon. We need more 3d printing articles like this.

I'm sorry about the unpleasant experience with the previous printer...
While I've seen people make some miniature compound bow, scaling it to regular size might be dangerous, because as far as I understand, bows are ofter strengthened with fiberglass right? Especially compound bows create such a force that I would be scared to pull the string.
I am not sure if I'll get involved in 3D printing construction though :D

3D Printing is an AWESOME technology!!!

I do not have a 3D printer, it would be awesome if i can have the opportunity to have one, so i'll make projections till one day i gather enough to buy one for me. 

If i could create anything on the printer i'll be creating toys for my son...but not every kind of toys else toys of my choice mainly created by mi imagination, toys you never gonna find in a common store.

Questions about 3D printing coming now to my mind are several but i let you with one in specific: is there a way to improve TIME spent in printing objects? I've heard time is the main problem qhen refering to 3D printers nowadays.

...and finally: YES, i like this format of articles. It's informative, entertainig and fun to read...i hope this kind of article keep  appearing from day to day at Crowdholding...as long as they aren't about jokes or something like that.

Good luck, and nice article!!!!

Thank you!
Some parents are indeed making custom toys for their kids based on their drawings and making them reality.

There is no way around it, 3D printing takes time. Several hours. There are however ways so you don't have to print all day and night. Where smoothness doesn't matter, you can have a thick layer height and it dramatically changes the speed of print. What most people also don't know is that prints are to some percentage hollow, with multiple choices of inside infill patterns to guarantee strength. You can set the percentage for example 15% and it is still surprisingly strong. Or you could go even lower and thicken the walls. Many possibilities, but yeah, it still takes a fair amount of time.

Don't listen to me because of who I am, I'm nobody like everone else.

Yes this was an interesting article, I had never heard of the use of resin like that, only the plastic type.

I have looked at 3D printing superficially before, but never really got interested because I don't really know what the material is suitable for making, and also because I get the impression many things cost more to 3D print than to buy so you would end up with a more expensive and also inferior product. I get the impression it is mainly for industrial prototyping and hobbyists creating ornaments for the love of the art of it.

I think CNC machines are much more interesting if they can become more versatile and easy to use, purely because plastic is not a particularly nice or useful material for the type of things you would want to make in the home, but wood and metal are much better. If 3D printing ever fulfills the technophile visions of people manufacturing products to use in their own homes it is much more likely to be from some kind of CNC machine than an actual 3D printer.

I guess my only questions would be about the nature of the material for the extrusion ones, as in what is it actually suitable for in making useable products rather than just ornaments or prototypes?

I really don't want to go too deep regarding the materials but I actually think that 3D printing is a bit cheaper. 1 kg roll of material can cost as low as $20 and you can print a lot of stuff with 1 kg.

You are correct with the prototyping and hobbyist part. As I described the layer height, the smoother you want the model, the more time it is going to take. Because of this, I consider a '3D printed product' just a buzz word. It is a great tool for hobbyists but very uneffective tool for massive manufactures.

I have to disagree with the strength. There are many materials you can print out of and all of them have different atributes, be it strength, temperature resistance, solubility and many more. Although yes, plastic is plastic and will never be as strong as wood or metal, I truly think it can be better than some plastic products you can buy. The beauty of 3D printing is that it also allows you to reinforce the model in many ways, even without changing how the model actually looks with outer supports.

As for the usability, you can use some 3D printed parts to fix broken things for a few cents. Say something you own uses a plastic gear and it breaks. You really don't want to buy the whole thing again, so you print just the gear. Since the 1 kg roll costs $20 and the gear can weight around 5 grams, you've repaired the thing for just a $0.1. This guy did exactly this: https://www.reddit.com/r/functionalprint/comments/butjhn/replacem...

Or, I once wanted to try playing ukulele without putting too much money in it, so I printed one, haha.

I first started reading about 3D printing in my local newspaper. There is a 3D printer company in my area called exone. I actually bought some of their stock.. I do not own a 3D printer but my stepson does and I have watched him print. It's fascinating to see basically plastic string/filament turn into an object! If I could make anything, it would be new discs for my neck as mine are deteriorating with age & causing me pain. I've read that in the future, all schools & possibly homes will have a 3D printer. When do you think that may be? I am very interested in your arricles. I want more people to learn about 3D printing. Body parts, food, airplane parts! Unbelievable! Yet true. It's crazy what people can think of and create!  hopefully my stock will make me some money

Biosafe prints that help people would be awesome. I've read an article about 3D printing custom beak for eagle that suffers with some illness, so I really think something like this for humans is just a matter of few years.
Some schools already have 3D printers but from what I've heard, many public libraries have some and their users can reserve a printing time to print whatever they want.

I have actually seen news stories about body parts, like a leg or hand so as time goes, there will be more. I also heard about libraries having printers too.
