Omni3D Factory 2.0 3D Printer Review

Specifications

GENERAL

The Omni3D Factory 2.0 is simple and reliable large format 3D printer. Omni3D not only worked on the kinematics of the printer, but also successfully applied solutions from the field of industrial design.

The printer can handle a wide range of plastics, including ABS. Check the video below:

For easy access, the printer has two large openings with viewing windows, and all its doors have magnetic catches. During operations or when the extruders and the table are moving, the doors stay locked.

This printer comes with HIWIN precision guides and threaded screws, which are reliable and provide the required rigidity. If PEEK or similar nuts are used on the screws, the unit can achieve printing at speeds of over 100 mm/s.

The kinematics of the printer inspire confidence. Everything is neat and beautiful, except for a few uneven surfaces.

The table is mounted on three single-thread screws and precision rail guides with independent stepper motors, which improve the leveling accuracy. The printer automatically autolevels and adjusts the extruder heights. You cannot adjust the table manually. Moreover, you cannot build a table map to compensate for unevenness is not provided.

The printer has a large build volume of 500 x 500 x 500 mm. The build plate has a heating element and heats up to 130°C.

Other features of the Omni3D Factory 2.0 include an insulated heated chamber, a separate filament storage chamber, and a closed compartment that houses the electronics. Two power connectors are responsible for the electronics and the heating elements.

A smooth glass is installed on the desktop in the printer. We glued Kapton tape on the glass bed during our testing activities to improve adhesion of complex engineering plastics, i.e., nylon, PC, PEEK.

The chamber camera heats up to 70°C. To control the temperature, a thermal sensor is installed inside the chamber. There is also an impeller enclosed in a casing on the lower part of the chamber. The impeller distributes hot air over the entire volume of the working area.

Additional fans are installed in the upper part of the chamber to avoid overheating.

The filament storage compartment is separated from the main working chamber by a solid metal wall with thermal insulation. The compartment has two reel holders that can easily accommodate two 2kg reels of REC plastic.

There is also a pair of mechanical encoders installed there. These two monitor the availability and supply of filament and count the amount of plastic used in meters.

In the uppermost part, there is an expansion tank for the SVO thermal barriers of extruders. This tank is divided into two circuits.

Finally, there is a radiator at the bottom of the case.

Omni3D Factory 2.0 has two independently suspended extruders. The extruders are E3D Volcano with an original design feeder and a thermoblock for cooling the thermal barrier.

Many 3D printers have problems printing flex filaments because, generally, the softer the fiber, the harder it is to print. Factory 2.0 eliminates this through its specially-shaped brass head holder that prevents tangling and winding of the filament around the extruder teeth.

This solution has been proven many times

The only difficulty that arises is when the filament is loaded into the extruder. Flex must be loaded into the extruder manually, i.e. – after unscrewing the filament clamp, insert the bar into the brass head holder, then close the extruder clamping lever. After this, you can start printing. ”

The extruders are mounted on a massive mounting plate. For movement, precision rail guides and multi-thread screws driven by stepper motors are used.

With the help of independent servo drives, the extruders are positioned in the Z-axis, for high-quality printing in two materials (with soluble supports or materials of different colors). The height of the extruders is adjusted automatically.

The extruders have thermoblocks operating at temperatures up to 360°C. Optional thermoblocks that can heat up to 420°C are also available.

The thermal barrier of each extruder is equipped with a water block and is effectively cooled when working in an environment with an elevated temperature, up to 70°C. The printed models are cooled using a turbine with split ventilation ducts.

Controls & Slicer Software

The controls are minimalistic. The panel mounted at the top of the printer at a 45° angle contains an ON/OFF button (separate), an emergency shutdown button (large and red) and a 6.8-inch touchscreen display.

The software interface is simple and intuitive. There are four main tabs in the menu. These are:

• Overview: This tab is divided into 2 blocks. The first block displays the temperature of the extruders, the table and the chamber, the name of the file selected for printing and the amount of filament used. The second block contains the button for selecting the control program file, START/STOP and PAUSE/RESUME printing.
• Temperature: In this section, you can set the temperature of the extruders, chamber and table. You can also enable forced cooling of the chamber and blowing of the part in the cooling submenu.
• Mechanics: This is responsible for controlling the movement of the extruder and the table, loading/unloading filament, leveling the table and calibrating the extruders along the Z axis relative to each other. You can run the extruder cleaning program and park the head unit in the far left corner of the camera.
• Other: This displays settings and information about the printer: model, serial number, software version and date, working hours and printing times. There are also additional tabs for setting the distance of the relative offset of the extruders along the X and Y axes and updating the printer’s firmware.

During printing, only Overview and Temperature are available. This prevents accidental change in the settings during the printing process from spoiling the quality of the printed model. Remember, this is an industrial use printer and quality is expected for any jobs sent.

Pausing the printer provides functions of positioning the extruder and loading/unloading filament. Also, the printer automatically pauses printing if the plastic has run out or the extruder is clogged.

In case of a complete power outage, printing cannot be continued. You will have to restart it.

What’s in the Box?

The Omni3D Factor 2.0 printer comes with:

• heat resistant gloves,
• protective glasses,
• wire cutters and
• putty knife.

The spatula supplied by the manufacturer is not very convenient. We prefer a slightly wider, thinner and more flexible one.

However, the quality of all the products is good.

Quality of Print

ABS Test Print

An art model was chosen as the first test sample to evaluate the overall print quality of the two extruders. We used ABS material.

On this model, you can see both overhanging elements and complex relief surfaces.

All the complex details of the model are printed well. The inactive extruder almost does not “snot”, even when fully heated. Cheaper printers often suffer from this.

Taking a closer look at the finished model, we can see that all layers are well sintered. Even the smallest channels and indentations were printed.

ABS/HIPS Test Print

Our next test was printing an impeller. This is what was printed:

The impeller was printed with ABS plastic with HIPS supports. The surface quality is high.

Next, we moved to a complex configuration cyclone. The cyclone is a system for cleaning air from mechanical impurities. The printed cyclone will be used in the chip removal system of the Solidcraft CNC 6090 router to separate large chips and dust.

The optimal material for the cyclone is ABS, because it is durable and durable. Moreover, the HIPS printed supports are easy to remove from it.

Due to its complex geometry, impressive dimensions and many threaded connections, the model is excellent for a comprehensive assessment of parameters such as overall print quality, surface quality, print accuracy and stability.

The total printing time was about 160-170 hours, for objects with a total volume of 1627 cc. excluding supports. The printer was exceptionally stable in printing.

Onmi3D Factory 2.0 demonstrated high quality print quality. All threaded connections came together without additional machining, and the HIPS supports were easily removed without leaving a trace.

Basic print parameters:

• Extruder temperature: 235°C (temperature is the same for both extruders)
• Table temperature: 100°C
• Chamber temperature: 70°C
• Nozzle: 0.4mm
• Layer: 0.2mm
• Print speed: 80 mm/s outer perimeter, 90 mm/s inner perimeter, 160 mm/s infill
• The control program was prepared in IdeaMaker from Raise3D

Of the negative aspects, the first layers laid on the supports were slightly warped. However, this did not affect the final result in any way.

You can decrease the speed of the lower dense layers to reduce this effect.

PEI Test Print (Ultem 1010)

Printing from PEI (Ultem 1010). The test model is very solid.

PET-G Test Print

A large PET-G part was printed. The print quality and speed left positive impressions.

Pros and Cons

Pros

• Large print area;
• Heated table and chamber, warm air circulation system;
• Reliable kinematics;
• Easy to operate, ready to work out of the box;
• Automatic leveling, automatic adjustment of the height of the nozzles;
• Nozzle cleaning system with waste storage container;
• Encoders that monitor the presence and movement of filament, automatic pause of printing at the end of filament or clogged extruder.

Cons:

• You cannot print large objects with refractory plastics, despite the large camera and the presence of thermoregulation;
• Minimal automation;
• To warm up the extruder to 420 degrees, flashing is required. This is officially allowed and the manufacturer even provides the necessary firmware and instructions;
• High price.

Conclusion

The Omni3D Factory 2.0 3D printer is very simple to operate and intuitive. Due to the heated chamber, it prints well with ABS and similar plastics at speeds of 100 mm/s for walls and 160 mm/s for filling.

Another advantage of the printer is its high-quality printing with two extruders. There are no material leakages from the inactive extruder. And the HIPS supports can be removed from the ABS part easily and naturally. The device also prints PET-G plastic well.

You can experimentally print small parts with materials such as PEKK and ULTEM. However, the 70°C chamber temperature is not enough for full-fledged work with them.

During testing, we achieved high-quality printing of only small elements from materials with a simple geometry, at a speed of 20 mm/s. For geometrically complex parts, the speed must be reduced to 10-15 mm/s. Large parts made from refractory structural filaments will most likely not be able to print, due to material warping during shrinkage, since 70°C is not enough for them.
