3D Printing Application - Automated Feeder

Autonomous Chicken Feeder is a project I was commissioned to have as inputs limited in scope and the ability to easily add feed. So I would like to tell you about such a project now. But before starting, I would like to suggest subscribing so as not to miss new materials.

You can watch the video, or by scrolling below there will be a text version of the material.

Problem statement

The beginning of this project was rather classic. I was approached by a person with a request to develop a project for an autonomous chicken feeder. I was given an electric feed dispenser, which, by the way, greatly facilitated the development of the project itself, since it remains only to make the feeder itself in which the feed will be distributed, as well as a container in which grain is stored and a valve for the possibility of removing the tank.

The following requirements were put forward as technical tasks:

• The height of the entire structure must be no more than 1m.
• Everything must be attached to the wall.
• Possibility to remove the grain container.
• Easy to install.

The tasks were set and I started developing

Development of autonomous chicken feeder

I started by thinking about what is better to print and what can be bought as a finished product. The result was that the valve, all brackets, the feed distributor would be printed, and the feed container would be purchased.

And this container was an ordinary 18 liter trash can.

Future feed storage tank.

The choice was in the direction of the bucket due to the fact that this bucket has a valve cover, thus no garbage will get into the feed, and it will be more difficult for chickens to get into the tank. Also, the cost of a finished tank is much cheaper than printing a similar one from scratch.

Simulation

I then proceeded to the modeling process itself. I decided to start by modeling the electric dispenser itself. Since it already exists and all subsequent geometry will be built from it.

A bracket for fixing the dispenser to the wall was also made right away.

Electric feed dispenser.

Next, the wall and floor were added, with the maximum dimensions possible.

The factory version of the feeder was taken as a model for the feeder with distribution. Only unlike the factory version, it was split in half to fit snugly against the wall, and the dimensions were adjusted to the size of the printer table.

Feeder model.

By this time a bucket had arrived from OZON, and I made a dimensional model to understand it throughout the project. And he began to develop a valve that is attached to the tank and inserted into the dispenser.

Valve model.

The valve itself is quite simple in design, a hole is cut out in the tank, the side of the valve that is adjacent to the tank and has a cone, and in order to prevent the feed from spilling, a plate and grooves are made into which it is inserted.

Valve model top view.

Well, how the finish was modeled for the bracket for the tank itself, its essence is simple, it is simply made in the form of an inverted letter P, and the tank simply clings to the side of this bracket.

Tank bracket model.

The result is a 3D model of an autonomous chicken feeder.

Seal of autonomous chicken feeder

The printing process itself was quite easy.

Brackets were printed from ABC plastic, as static rigidity was needed.

Tank bracket.

The valve was printed from PETG plastic.

Printed valve

The feeder itself was printed out of PLA plastic, and the reasons for choosing PLA were that it is quite durable, and it is also safe in contact with food, to be honest I don’t know how relevant this is for chickens, but still. The disadvantage of PLA is the low operating temperature, but since this feeder will be in the chicken coop, there will be no strong heating.

Printed feeder and cover.

Installation

General view of the installation kit.

Freestanding Chicken Feeder has been unsealed and fitted. I came to the customer.

The customer examined everything and started the installation process, how the process went can be seen in the video.

Mounted independent chicken feeder

But I can definitely say that the installation process went quickly (about 15-20 minutes).

As a result, the height of the finished structure was 60 cm, and therefore it was decided to place the feeder on the outside of the chicken coop for the summer period.

Total

This is how the project turned out, and this project shows the possibilities of 3D printing, namely, obtaining those forms that cannot be bought in the factory video, for example, a feeder, no matter how much I searched, but I could not find a half version of this feeder. Of the minuses, I can only say that the mounting ears at the feeder broke off, but this happened because I foresaw that the feeder would stand on the floor, and the fasteners are needed so that the feeder does not crawl, but during installation you can see that the feeder was attached only to the wall and quite high above the ground. As a result, the chicken decided to sit on this feeder and broke off the fasteners.

Write in the comments what you think about this project, or suggest your own. Also subscribe to the channel so as not to miss new videos, and like it, it helps the channel a lot.

Metal 3D Printing - The Essential Guide

There is no hotter trend in 3D printing today than metal. We will talk about metal printing at home, how it is done on an industrial scale, about technologies, applications, printers, processes, prices and materials.


Metal 3D printing has grown in popularity over the past few years. And this is quite natural: each material offers a unique combination of practical and aesthetic qualities, can be suitable for a wide range of products, prototypes, miniatures, decorations, functional details and even kitchen utensils.

The reason metal 3D printing has become so popular is because the printed objects can be mass-produced. In fact, some of the printed parts are just as good (if not better) than those made with traditional methods.

In traditional production, working with plastic and metal can be quite wasteful - there is a lot of waste, a lot of excess material is used. When an aircraft manufacturer makes metal parts, up to 90% of the material is simply cut off. 3D printed metal parts require less energy and waste is reduced to a minimum. It is also important that the final 3D printed product is up to 60% lighter than a traditional part. Billions of dollars could be saved in the aviation industry alone—mainly through weight savings and fuel savings.

So, what do we need to know about metal 3D printing?

Metal 3D printing at home

If you want to make objects at home that will look like metal, your best bet is to look at metalized PLA filaments (Photo: colorFabb)

Where to start if you want to print metal objects at home ? Given the extreme heat required for true metal 3D printing, a conventional FDM 3D printer will not be able to do this.

It is unlikely that in this decade it will be possible to print with liquid metal at home. Until 2020, you probably will not have a printer specialized for this purpose at home. But in a few years, as nanotechnology advances, we may see significant developments in new applications. This can be 3D printed with conductive silver, which will emit in much the same way as it does in 2D home printers. It will even be possible to mix different materials like plastic and metal in one object.

Materials for metal 3D printing at home

Even though you can't print actual metal objects at home, you can turn to plastic filament that has metal powders added to it. ColorFabb, ProtoPasta and TreeD Filaments all offer interesting metal-PLA composite filaments. These filaments, containing a significant percentage of metal powders, remain pliable enough to be printed at low temperatures (200 to 300 Celsius) on virtually any 3D printer. At the same time, they contain enough metal to make the final object look, feel, and even weigh like metal. Iron-based filaments even rust under certain conditions.

But you can go further. Typically, up to 50 percent metal powder is added to 3D printing filament. Dutch company Formfutura says they have achieved 85 percent metal powder with 15 percent PLA. These filaments are called MetalFil Ancient Bronze and Metalfil Classic Copper. They can be printed even at "moderate" temperatures from 190 to 200 degrees Celsius.

Here are the key points about metal printing at home

• Gets a unique metal surface and look
• Ideal for jewelry, figurines, housewares, replicas
• Durability
• Objects are not flexible (structure dependent)
• Objects do not dissolve
• Not considered food safe
• Typical print temperature: 195 - 220°C
• Extremely low shrinkage on cooling
• No table heating required
• Printing complexity is high, requires fine tuning of nozzle temperature, feed rate, post-processing

Preparing your home printer for metal 3D printing

Since getting metal 3D prints is more difficult than usual, you may need to upgrade your 3D printer nozzle, especially if you are an entry-level printer. The metal filament wears it out quickly. There are hard-wearing hot-ends (like the E3D V6) that are themselves made of metal. They can withstand high temperatures and fit most printers. Be prepared for the fact that the nozzles will have to be changed frequently, because the metal filament is very abrasive.

You will also need to take care of the final finishing of the surface (cleaning, grinding, oiling, waxing or priming) so that the printed metal object shines as it should.

How much does metal filament for 3D printing cost?

And what about metal filament for 3D printing? - you ask. Here are a few examples:

• ColorFabb's 750 gram Bronzefill spool is $56.36
• ColorFabb 750g Copperfill Coil $56.36
• Protopasta's Polishable Stainless Steel PLA Composite is $56 for 56 grams of
• Rustable Magnetic Iron PLA Composite from Protopasta is $34.99 for 500 grams of

Industrial Metal 3D Printing

But what if you want better results or even full metal 3D printing? Should a real "metal" 3D printer be purchased for business needs? We wouldn't recommend it - unless you're going to be doing it every day. A professional metal 3D printer is expensive: EOS or Stratasys devices will cost you 100-500 thousand dollars. In addition, the costs will be even greater, since you will have to hire an operator, a worker to maintain the machine, as well as to finalize the printouts (polishing, for example). Just a note: In 2016, an affordable metal 3D printer didn't exist.

Lowering Metal 3D Printing Costs

If you are not going to start a metal 3D printing business, but still need a professionally 3D printed metal part, it is best to contact the appropriate company that provides such services. 3D printing services like Shapeways, Sculpteo and iMaterialise offer direct metal printing.

They currently work with the following metal materials in 3D printing:

• aluminum
• steel
• brass
• copper
• bronze
• sterling silver
• gold
• platinum
• titanium

If you are a jeweler, you can also order wax models for casting in precious metals.

If we talk about wax models, then in most cases they (with subsequent melting) are used when printing with metals (including gold and silver). Not all orders are carried out directly by these firms. They usually turn to other metal 3D printing companies to complete the order. However, the number of such services around the world is growing rapidly. In addition, metal 3D printing techniques are becoming more and more common in companies that offer such services.

The reason big companies love 3D printing so much is that it can be used to build fully automated lines that produce "topologically optimized" parts. This means that it is possible to fine-tune the raw materials and make the components thicker only if they must withstand heavy loads. In general, the mass of parts is significantly reduced, while their structural integrity is preserved. And this is not the only advantage of this technology. In some cases, the product turns out to be significantly cheaper and affordable for almost everyone.

Please note that metal 3D printing requires special CAD programs for modeling. It is worth paying attention to the recommendations of Shapeways - 3D printing metal guidelines. To delve further into the topic, check out Statasys’ information on related 3D printers and the nuances of metal 3D printing.

Here are some examples of Benchy test model prices for metal 3D printing:

• Metal plastic: $22.44 (former alumide, PLA with aluminium)
• Stainless steel: $83.75 (plated, polished)
• Bronze: $299.91 (solid, polished)
• Silver: $713.47 (solid, mirror polished)
• Gold: $87.75 (gold plated, polished)
• Gold: $12,540 (solid, 18K gold)
• Platinum: $27,314 (solid, polished)

As you might expect, the prices for solid metal 3D printing are quite high.

Metallic 3D printing. Applications

GE LEAP aircraft engine parts 3D printed at Avio Aero (Photo: GE)

There are several industries already using 3D printers to make everyday objects - you may not even know that these objects are printed.

• The most common case is surgical and dental implants, which are considered the best option for patients today. Reason: they can be tailored to individual needs.
• Another industry is jewelry. Here, most manufacturers have abandoned resin 3D printing and wax casting, switching directly to metal 3D printing.
• In addition, the aerospace industry is becoming more and more dependent on 3D printed metal objects. The Italian company Ge-AvioAero was the first to do all-metal 3D printing. It manufactures components for LEAP aircraft engines.
• Another industry targeting metal 3D printing is the automotive industry. BMW, Audi, FCA are seriously considering this technology, not only for prototyping (3D printing has been used for this for quite some time), but also for making real parts.

Before metal 3D printing really takes off, however, there are some hurdles to overcome. And first of all, this is a high price, which cannot be made lower than during molding. Another problem is the low production speed.

Metal 3D printing.

Technologies

Most metal 3D printing processes start with an “atomized” powder

You can talk a lot about “metal” 3D printers, but their main problems remain the same as any other 3D – printers: software and hardware limitations, material optimization and multimateriality. We won't talk too much about the software, we'll just say that most of the major specialized software companies, such as Autodesk, SolidWorks and solidThinking, try to emphasize as much as possible the fact that as a result of the 3D metal printing process, you can get any shape you want.

In general, printed metal parts can be as strong as parts made by traditional processes. Parts made using DMLS technology have mechanical properties equivalent to casting. In addition, the porosity of objects made on a good "metal" 3D printer can reach 99.5%. In fact, manufacturer Stratasys claims that 3D printed metal parts perform above industry standards when tested for density.

3D printed metal can have different resolutions. At the highest resolution, layer thickness is 0.0008 - 0.0012" and X/Y resolution is 0.012 - 0.016". The minimum hole diameter is 0.035 - 0.045". formed layer)

The metal 3D printing process used by most relevant large companies today is called Powder Bed Fusion. This name indicates that some source of energy (a laser or other energy beam) melts an "atomized" powder (i.e., a metal powder that is carefully ground into spherical particles), resulting in layers of a printed object.

There are eight major manufacturers of metal 3D printers in the world that already use this technology; while we are talking here, there are more and more such companies. Most of them are in Germany. Their technologies are called SLM (Selective Laser Melting - selective laser fusion) or DMLS (Direct Metal Laser Sintering - direct metal laser sintering).

Metal 3D-printing process No. 2:




binder Jetting (spraying the binder)

in 3DP-technology EXONE PROTECTIONS PROTECTIONS PROTECTIONS PROTECTIONS OF THE RIGHT : ExOne)

Another professional approach that also uses a powder base is called Binder Jetting. In this case, the layers are formed by gluing metal particles together and then sintering (or fusing) them in a high-temperature furnace, just like it is done with ceramics.

Another option, which is similar to working with ceramics, is mixing metal powder into metal paste. A pneumatically extruded 3D printer (similar to a syringe bioprinter or an inexpensive food printer) forms 3D objects. When the required shape is reached, the object is sent to the furnace, i. e. in the mountains

This approach is used in the Mini Metal Maker, apparently the only inexpensive "metal" 3D printer.

Metal 3D printing process #3: 9Metal Deposition This is not entirely true. Of course, on some desktop device, simply fusing metal threads onto the base will not work. However, very large steel companies can do it. And they do. There are two options for working with "metal surfacing".

One is called DED (Directed Energy Deposition) or Laser Cladding. Here, a laser beam is used to melt the metal powder, which is slowly released and solidifies as a layer, and the powder is fed using a robotic arm.

Normally the whole process takes place in a closed chamber, but the MX3D project used conventional 3D printing techniques to build a full-size bridge. Another option for metal fusion is called EBAM (Electron Beam Additive Manufacturing - additive electron beam technology), which is essentially soldering, in which a very powerful electron beam is used to melt 3 mm titanium wire, and the molten metal forms very large finished structures. As for this technology, its details are known so far only to the military.

Metal 3D printing. Metals

3D Printing Metal #1: Titanium

Pure titanium (Ti64 or TiAl4V) is one of the most commonly used metals for 3D printing and is definitely one of the most versatile, strong and lightweight. Titanium is used both in the melting process in a preformed layer and in the process of spraying the binder and is used mainly in the medical industry (for the manufacture of personal prostheses), as well as in the aerospace industry, automotive and machine tools (for the manufacture of parts and prototypes). But there is one problem. Titanium is very reactive and explodes easily in powder form. Therefore, it is necessary that titanium 3D printing takes place in a vacuum or in an argon environment.

3D printing metal #2: Stainless steel

Stainless steel is one of the cheapest 3D printing metals. At the same time, it is very durable and can be used in a wide range of manufacturing and even artistic and design applications. The type of steel alloy used also contains cobalt and nickel, is very difficult to break, and has a very high elasticity. Stainless steel is used almost exclusively in industry.

3D Printing Metal #3: Inconel

Inconel is a superalloy manufactured by Special Metals Corporation, its registered trademark. The alloy consists mainly of nickel and chromium and is very heat resistant. Therefore, it is used in the oil, chemical and aerospace (for black boxes) industries.

3D Printing Metal #4: Aluminum

Due to its lightness and versatility, aluminum is very popular in 3D printing. Aluminum alloys are commonly used.

3D Printing Metal #5: Cobalt Chrome

gap). It is most commonly used in the manufacture of turbines, dental and orthopedic implants, where 3D printing has become the dominant technology.

3D printing metal #5. Copper and bronze

With some exceptions, copper and bronze are used in wax melting processes, rarely in layer melting. The fact is that these metals are not very suitable for industry, they are more often used in the manufacture of works of art and crafts. ColorFabb offers both metals as the basis for a special metal filament.

3D printing metal #6. Iron

Iron, incl. magnetic, also mainly used as an additive to PLA-based filaments, which are produced, for example, by ProtoPasta and TreeD.

3D printing metal #7. Gold, Silver and Other Precious Metals

Most preformed melt process companies can 3D print precious metals such as gold, silver and platinum. Here, along with the preservation of the aesthetic properties of materials, it is important to achieve optimization of work with expensive starting powder. Precious metal 3D printing is required for jewelry, medical applications and electronics.

Metal 3D printing. Printers

Do not even hesitate - the purchase of a metal 3D printer will not pass without a trace on your budget. It will cost at least 100-250 thousand dollars. Here is a list of a variety of "metal" printers, some of which can be found in firms providing 3D printing services.

Metal 3D Printer #1:




Sciaky EBAM 300 - metal filament printing

If you need to print really large metal structures, Sciaky's EBAM technology is your best bet. By order, the device can be built in almost any size. This technique is used mainly in the aerospace industry and the military.

Sciaky's largest production printer is the EBAM 300. It prints objects in a volume of 5791 x 1219 x 1219 mm.

The company claims the EBAM 300 is also one of the fastest industrial 3D printers on the market. A three-meter-sized titanium part for an aircraft is printed on it in 48 hours, while the material consumption is about 7 kg per hour. In general, forged parts that usually take 6-12 months to complete can be made in 2 days with this 3D printer.

The metal layers are first cut and then ultrasonically welded. The largest Fabrisonic 7200 printer operates in a volume of 2 x 2 x 1.5 m. The metal powder 3D printer is the Concept Laser XLine 1000. It has a modeling volume of 630 x 400 x 500 mm and is the size of a house.

Its German company, one of the main suppliers of 3D printers for aerospace giants like Airbus, recently introduced a new machine, the Xline 2000.

This machine uses two lasers and has a working volume of 800 x 400 x 500 mm. Uses LaserCUSING laser technology (a variant of selective laser fusion) from Concept Laser, which allows you to print alloys of steel, aluminum, nickel, titanium, precious metals and even some pure substances (titanium and stainless steel).
