Features

What makes any 3D printer efficiently functional is the set of features that differentiate it from others. And below mentioned are some of such features of Atom 2.5 EX and their explanation that separates it from other printers in the same price range.

Sort of making it special than its competitors. We will go one by one decoding the printer so that you get to know why it’s actually worth buying this printer.

Two in one Dual Extruder 

Being an FDM 3D printer, it’s rare to get one with a dual extruder in the price range that Atom 2.5 EX is offered. So, hats off to Layer One for their efforts.

Now, coming to what does a dual extrusion system do that makes a printer so appealing? Well, normally dual extrusion systems are known to print in different modes such as Mirror, Duplicate, etc.

Atom 2.5 EX also allows you to print with two different filaments. This actually means that the work done by a 3D printer that has a single extruder can be done in half the time by Atom 2.5 EX.

So, if you purchase this printer for mass production of parts and functional prototypes you would be able to finish a product in half the time than other manufacturers with a single extruder. Isn’t that magical?

The dual extruder can also work the other way round. It can build a single object in half the time than single extruder 3D printers.

Talking specifically about Atom 2.5 EX, it features a single nozzle design that allows the use of dedicated, dissolvable supporting material which is very useful while making intricate geometries.

The printer also permits two-color printing. Imagine! All the beautiful geometries that you have observed in more than one color can be 3D printed. How wonderful, isn’t it?

No Manual Leveling

Atom 2.5 EX has an automatic bed leveling system. So, as soon as you feed the printer with a sliced 3D printed file, it will adjust the height of the nozzle system from the print bed automatically.

Meaning that you will not have to open the screws and adjust the height manually. Manual leveling of the print bed according to the part’s geometry is a bit of a hassle especially if you haven’t done it before.

Additionally, automatic bed leveling will ensure that you have got the first layer of your print correct. The first layer of any part is said to be it’s fundamental.

If that is not laid correctly, the complete part can fail or has higher chances of failing when put into application. Thanks to Atom 2.5 EX’s manufacturers, you as its users will never have to face such an issue.

No Oozing, no Scraping

Though there are more intricacies while printing Atom 2.5 EX than normal single extruder 3D printers, it does not ooze out. Additionally, you require no scraping or fuss while removing parts that are already 3D printed.

If the nozzle oozes out, the melt flow rate increases and there is more amount of melted material on the print bed than needed.

This will decrease the overall print quality of the part. But unlike other 3D printers, Atom 2.5 EX does not let the nozzles ooze out.

We suggest taking a look at our 3D Printing Tips: How to Fix & Prevent 3D Print Ooze for more information.

A Quick-Release Heated Glass Build Plate

For decreasing the overall print time, Atom 2.5 EX has installed a heated build plate. And it does not take a lot of time to get it heated.

On the other hand, because of heating up the build plate, you can print with filaments that have a higher glass transition temperature.

Also, the build plate is made of glass material which will mean that your 3D printed parts will easily be stuck on it. And you would require no painting tape or other glues for good bed adhesion. This will also lead to a decrease in the overall cost of printing a part with the printer.

Hot End Lined with Thicker PTFE Tubing

Nozzle system is the heart of a 3D printer. So, if you have a nozzle that can withstand high temperatures and can reach those temperatures within a short time, your complete process of 3D printing will expedite.

That’s exactly the case with Atom 2.5 EX. Its hot end can reach even high temperatures within a short span of time, thereby letting you start 3D printing instantly.

Thick PTFE tubing safeguards the transfer of melted hot filament from the nozzle to the print bed. This is essential because if the transfer material is not good, the complete 3D printing process can fail at the very start.

But PTFE is a trustworthy and reliable material that will ensure that even the material with highest melting point will be easily transferred using it.

Customized Spool Holder

Atom 2.5 EX is a dual extruder 3D printer, meaning that you can print using two different filament spools at a time. Therefore, you will definitely need an extra safe arrangement that you do not necessarily need with single extruder 3D printers. And this involves more intricacy.

Customized spool holder, like the one in Atom 2.5 EX safely ensures that the complete material is made to pass through and connected with the nozzle system and the extruder.

You can rely on its calculation which will never fail and stop the 3D printing process in the middle. It’s a tried, tested, and proven arrangement for safe 3D printing of parts and functional prototypes.

Specifications

Atom 2.5 EX is a plug-and-play 3D printer. You can simply take the printer out from the box in which you receive it, connect to the power supply, turn the printer on, initiate the setup, upload the file using one of the modes of connection and start printing.

However, you do get a manual with the printer which you are advised to read before starting to 3D print.

Print Type/Cost

FDM 3D printing is a simple process to manufacture parts and functional prototypes. It is easy to understand especially for beginners in the field.

Herein, a solid filament spool of material is fixed on the filament spool holder which is connected to the extruder and the nozzle system.

After that, the material’s glass transition temperature is known and the extruder’s temperature is made to reach the same.

Once the temperature is reached and the filament has melted, it is allowed to flow from the nozzle to the print bed. The flow is regulated via the geometry of the part that is fed to the printer.

One by one layer is laid until the geometry of the part is completed. Then, the 3D printed part is cooled down and sent for post-processing.

FDM 3D printing is a simple process that sometimes needs the help of support structures as well.

The cost of 3D printing a part via FDM 3D printing technology is lesser than that with other 3D printing technologies.

Although the cost depends on various factors such as the geometry of the part, the geometry of the support structures, level of infill, the type of filament you are 3D printing with and its cost, etc, it’s relatively lower.
