One of the novelties in the Russian market at the end of 2016 was the 3D printer Raise3D N2 Dual. This is a newcomer to our country, and his appearance created some intrigue. The printer has a memorable appearance that distinguishes it from another similar technique. Appearance is certainly good, but does it have any advantages over other similar machines to become a popular model?
What Does the producer offer us?
First of all, a rather large print area attracts attention: 305 x 305 x 305 mm. This is more than the standard 200 x 200 x 200 mm area that most other additive manufacturers have.
The Raise3D N2 Dual model, as seen from the designation "Dual", has two extruders, which makes it possible to print complex models with supports from soluble materials For example PVA). This combination – a large print area and two extruders, is not common.
- The material used for 3D printing: PLA, ABS, Filaflex, PVA, PC, Hips, Nylon, Rubber, Flex (Thread diameter 1.75 mm ).
- Printable area: 305 х 305 х 305 mm;
- The height of the layer along the Z axis: from 10 to 200 microns (0.01 to 0.2 mm)
- Diameter of the nozzle: 0,4 mm;
- The presence of a closed camera 3D printing: Yes;
- Heated table: Yes, up to 110 ° C;
- Extruder temperature: up to 300 ° C;
- Number of printheads: 2;
- Presence of touch screen control: Yes
The appearance of the 3D printer leaves the impression that not only engineers but also designers worked on its appearance … Unfortunately this is not common. Basically, big companies are serious about this, they are the main players on the market. Let's write in a plus.
The abundance of transparent panels leaves a feeling of lightness and openwork design. This is achieved by the fact that transparent areas are located, including in the corners of the body.
Original design and design solution.
At the same time, the printer has a rigid frame made of aluminum, which has a positive effect on the quality of the print.
The quality of manufacturing and assembly at height. This can be seen from the photo below.
The coils with plastic are installed side by side one above the other and closed with a transparent door. Thanks to this decision, we can monitor the amount of remaining plastic. In this case, the coils do not protrude beyond the frame. And the plastic itself is protected from dust and moisture (due to being inside the chamber, where there is no moisture from the heating of the table and the extruder, and the plastic itself dries up if it was previously stored without a ZIP package).
Let us dwell in more detail on the features of 3D printer mechanics.
Two guide shafts and ball screws are installed on each side of the table. The working table moves along the four guides, which makes it possible to achieve the stability of the movement and to avoid this phenomenon wobbling (literally "oscillation" – stepped side surface).
View of the guide rolls from the coils .
All wires in the 3D printer are hidden in special boxes. No screeds and other signs of handicraft production. All this improves the appearance and adds reliability. Again, the feeling of factory assembly and complete completeness of the design.
The case has a completely closed structure. This allows us to create a favorable temperature regime for high-quality printing, plastics with high shrinkage. For example, for high-quality printing, the most popular material is ABS, a closed case is one of the most important conditions, after a heated table.
The heated table in the printer is also present. Recently, many manufacturers have a tendency to refuse heating. But it crosses out the list of available materials, the popular ABS, and creates problems with printing some other materials. The creators of Raise 3D decided not to limit their customers, by any frame. And so the printer can use any available materials for printing.
The glass on the working surface is removable, which makes it very comfortable to work. The table itself can be heated to 110 ° C. This is sufficient for all materials used in 3D printers. Heating the table to operating temperature takes very little time.
Literally 5-7 minutes. That compared to 10-15 minutes for many other printers, it looks like a serious advantage.
The table calibration is as much as possible automated. It will cope with an absolute beginner in 3D printing. Additional knowledge is not required. The printer is designed for a wide range of users. It can be seen that the manufacturer proceeded from the principle of "3D printing immediately out of the box."
At the inner edge of the 3D printer, LED work area lighting is installed. This allows you to monitor the printing process and monitor it without having to open the working chamber.
The printer in the process of printing.
Kinematics of the printer is based on the scheme used in 3D printers Ultimaker. Just look at this photo below.
The same guides that simultaneously act as axles for the drives of the extruder. What gives such a decision? The maximum simplification and simplification of the design. This positively affects the print quality and reliability of the printer. Plus this design is compact enough that allows to use the internal space of the printer as much as possible effectively. Here we see a large print area of 305 x 305 x 305 mm, with a fairly small size of Raise 3D.
In contrast to Ultimaker, the Raise3D printer uses a direct-extruder with two nozzles of the original design.
In order to preserve the size of the print area, the extruder drives were not placed side by side , As is usually practiced. In this 3D printer, the motors are placed vertically above each other. This allowed to create a very compact design. In contrast to other 3D printers, the two-extruder and single-extruder versions of 3D printers Raise3D have the same print area. In addition, I want to note the important advantage of direct-extruders – this is the possibility of problem-free printing with flexible materials.
The picture below shows how it was realized.
Extruder maintenance, thanks to transparent panels and simple construction, does not present difficulties.
The 3D printer Raise3D N2 Dual has a default nozzle diameter of 0.4 mm. It is possible to replace the nozzle with a different diameter. But there are no other diameters in the delivery set. They are offered by the manufacturer separately. Available in sizes from 0.2mm to 0.8mm
The extruder provides heating up to 300C. This allows you to print all available materials for 3D printing (ie printing without restrictions on materials).
It is possible to operate the 3D printer both from a computer and using an autonomous touch-screen color display.
The menu is intuitive. The management of the printer will not cause difficulties.
A large list of settings that will satisfy the needs of both beginners and advanced users.
In the upper corner of the screen you can see the battery icon. The display (and this is a full-fledged tablet computer) has an autonomous power source. With its help, a function is implemented that does not occur in other 3D printers, but is very convenient.
When the power is turned off, the printer enters standby mode and stops printing. However, the current status of 3D printing with all parameters remains in the memory of the standalone computer.
The introduction of this function will save a lot of nerves for users of the 3D printer, especially when printing large models in 20-30 hours. Moreover, this solution is used only for 3D printers Raise3D series N2. Other manufacturers can not pamper users with this functionality.
The internal electronics of the printer (display / tablet) is based on the processor * Freescale imx6, Quad core 1Ghz ARM processor *, RAM – * 1GB *.
The built-in flash drive has a capacity of * 8GB *. Operating system OS: * Embedded Linux *.
Recently, there has been a trend towards the use of more efficient solutions to standard Arduino to help or instead, in 3D printers. This positively affects both the quality of the press and the comfort of managing such equipment. The monochrome screen from the Arduino package is of course hardcore, and by Meiker. But we live in the 21st century and the touch screens and remote device management are already tightly integrated into our lives.
To manage 3D the printer has the following interfaces:
– 4 USB ports for connecting Flash-cards and web-cameras
– 1 Ethernet – to connect to the network for remote control
– 1 port for SD card
Raise3D N2 Dual has the ability to connect a web camera for remote printing control.
Panel of external interfaces
WiFi and Ethernet provide an opportunity to place Raise 3D in a convenient location of the office, regardless of the location of the computer operator's 3D printer. This enables remote control and printing control via a web camera. The thing is necessary and useful for the professional use of such equipment.
About the technical merits of the 3D printer we told. But in what form will it be delivered to the buyer? We all know about the quality of transportation of goods across Russia …
3D printer Raise3D N2 Dual has reliable packaging. This allows to avoid damage during transportation.
Inside the printer, all mobile elements are fixed with special plastic clips. Moving 3D printer nodes inside is excluded. This moment is very important.
Complete set of 3D printer standard: instruction manual in Russian, set of tools for 3D printing, flash card, USB cable, fittings, clips. In addition to the tools, two coils of the proprietary PLA are supplied in the kit.
The printer is equipped with its own slicer, called ** ideamaker **. It can be downloaded for free on the manufacturer's website.
Slicer is a universal solution. It has the ability to configure other printers, except Raise 3D.
The software has a large number of settings and extensive tuning capabilities. It is possible to prepare for printing a complex model.
For example, in this slicer (the general name of programs for preparing a model for printing), there is the possibility of manual installation of supports. This function is present literally in a couple of other programs, despite all their diversity.
The model can even be cut to pieces. Carry out a verification of the correctness of the 3D model and correct any errors and shortcomings.
Additionally there are functions of remote control of 3D printer. You can create a "farm" of 3D printers and manage them using a single computer. The ideamaker software runs under Win, Mac and Linux. Full set, for every taste.
Operation of the
The design and capabilities of the printer are reviewed. And how does he end up working?
After turning on, you can only hear the rustling of the cooling fans. We start printing, and the moment of truth comes.
What is the noise level from a 3D printer when printing? Usually a 3D printer starts filling the neighborhood with different sounds. From quiet rustling and funny melodies to metal clang.
Raise 3D on the background of other 3D printers practically does not make a noise. Rustling motion along the guides and a small hum of the fan. Looking at the printing area it is clear that printing large models will take a long time. And here a comfortable, low noise level adds a big fat plus to the printer's characteristics.
The noise level is, of course, an important factor. But the main thing is how the printer prints.
The 3D printer Raise3D N2 Dual prints very well, all the same affects the quality of components, kinematics, and high-performance control electronics.
Examples of products printed on the printer:
The height of the layer is 150 microns (0.15 mm), without treatment
The height of the layer is 200 microns (0.2 mm), without treatment
Print speed at height. 80-100 mm / sec the printer produces without reducing the quality.
According to the manufacturer, it can print a layer of 10 microns (0.01 mm). This is not surprising, since very high-quality components are used in the mechanics of the 3D printer.
As you know, you can say anything. But the real value is only the result. And we can see it in the photo. And it's very impressive.
It's easy to work on Raise 3D. Intuitive touch screen control and advanced software make it possible to obtain excellent results when printing.
Maintenance of the printer, thanks to a thoughtful design, does not present a problem for any user.
