The printer is successfully used for prototyping as well as small-scale manufacturing. Some of the examples where it has been tried and tested were print figures, table games, and miniatures.

So, in this article let’s try to find out what makes Fabtop Tech Optimus C1 a printer that can be used for such applications efficiently. We can do that by looking at various aspects of the printer. Ready?


The Optimus C1 is a hybrid machine offering you an affordable and modular three-in-one system that comprises FDM 3D printing technology. It can be used for laser cutting, CNC milling, as well as for desktop 3D printing to fulfill the manufacturing needs of individual makers.

Amazing Print Quality

As mentioned above, the Optimus C1 3D printer is an FDM 3D printer that can print layers of 50 microns height. Using it you can produce parts with amazingly smooth exterior surfaces.

The printer’s rugged structure is responsible for providing great accuracy and, also clarity of details. As a 3D printer, Optimus C1 can produce big parts with a maximum layer height of 0.6mm or a build area of 280 mm * 280 mm * 280 mm.

Switching Between 3D Printer Head and Laser Head in Five Minutes

This is a very important feature of FabTop Tech Optimus C1! It lets you change from one technology to the other for producing parts and functional prototypes within minutes.

The printer manufacturer FabTop has kept the arrangement in such a manner. The complete construction of Optimus C1 is made of a customized mold of Aluminum profiles that are light in weight and yet as strong as a tank.

You can transform your C1 into a Laser engraver/cutter for engraving beautiful gray photos on wood, and even steel surfaces with the printer manufacturer’s 7 Watt laser head.

The point to be noted that the operator’s safety is firstly kept in mind by the manufacturer even when working with a laser!

CNC Milling

By switching from either laser engraving or 3D printing to the milling head, you can start engraving a variety of materials. Its 16 millimeters in diameter light bar ensures high processing accuracy.

The printer’s independent Z-axis drive system and CNC cutting space provide you with higher stability and precision than other printers.

The laser tool head completes the Optimus C1 allowing you not only for a stable but also for accurate laser engraving and cutting.

Printing with Various Materials

Overall, Optimus C1 can be termed as a multi-purpose, multiple-technology using as well as multiple-materials offering for making objects. It can directly 3D print with PLA, nylon, ABS, resin, wood, metal, and other materials.

Switching from 3D printing to laser engraving can be done on Optimus C1 using a range of different materials, including aluminum, wood, PCB board, and others.

When you have lots of varieties of materials, you can easily make objects for more than one application! And that’s where Optimus C1 is handy like no other.

Modular Design

Optimus C1 has an innovative modular design in the sense that it has only 8 modular parts when you unbox it. All modules of this innovative three-in-one 3D Printer are designed and engineered for an uncomplicated assembly.

Because of this, you can start printing using the 3D printer from the moment you unpack the box in less than an hour! Another benefit of this modular design is that your shipping cost can be dramatically reduced. In a nutshell, the 3D printer is very flexible.

Closed Print Chamber

One of the eccentricities of printers with closed chambers is that it permits you to print with materials that have a higher melting temperature.

As a matter of fact, closed print chambers are known to generate more temperatures than open print chambers, and that too speedily.

So, by offering their 3D printer a closed print chamber, Fabtop wants to grant you the freedom of dealing with more than one 3D printing material.

Not only limiting you to PLA but also allowing you to print with ABS and other materials.


The printer prints objects using FFF i.e. Fused Filament Fabrication also known as Fused Deposition Modeling 3D printing technology. For 3D printing objects, Optimus C1 offers a build volume of 280 mm * 280 mm * 280 mm.

For Laser engraving the area offered is 280 mm * 280 mm, whereas for CNC milling it comes to 280 mm * 240 mm * 280 mm.

Each and every part or functional prototype that you 3D print on the printer has a minimum layer height of 50 microns.

The printer weighs 45 kilograms and hence transporting it from one place to another is not that big of an issue. You get the options of PLA, nylon, ABS, resin, wood, metal, and other materials for 3D printing parts that can be used for various applications.

Optimus C1’s outer dimensions are 574 mm * 504 mm * 612 mm. The maximum extruder temperature that the printer can withstand is 295 degrees Celsius.

The frame of the printer is made from Aluminum which is a material that offers it a considerable amount of stability and not allows it to vibrate with any of the manufacturing processes.

It has a single extruder and can be connected via USB cable for transferring sliced files. The printer comes to your place in a fully assembled model.

First Impressions

Febtop Tech Optimus C1

The front view of Optimus C1 gives you a feel of a compact machine that’s packed with mechanisms to create parts in three different ways i.e. Laser Engraving, 3D printing as well as CNC milling.

The rectangular-shaped machine looks solid at the very first appearance. It stands on four legs each of which is fitted with small steel stands.

As mentioned above, the body is made of Aluminum thereby giving you the required amount of stability needed for producing larger build volume parts.

The print chamber of Optimus C1 can be accessed via the door that can be opened for removing the finished part.

Just beside the door handle, there is a display screen that shows various functions and aspects of the printer.

What makes this printer look stylish is the black color with yellow stripes. The overall design of Optimus C1 makes it ideal for education, digital crafting as well as production.


With the 3D printer, in the box that’s shipped to you, you receive,

  • Parts for setting up the printer
  • 3D printing head
  • CNC milling head
  • Engraving laser Tool kit
  • Power supply and power cable
  • Quick Start Guide

That is apart from the printer itself. It is advisable to read the quick start guide before starting to print with Optimus C1. This will make you comfortable with the functionality of all the parts in the printer.

Apart from that, the printer comes completely assembled, you can start to print with it simply by plugging it into the power supply at your place.

Printing Type/Cost

FFF or FDM 3D printing technology is the mechanism the Optimus C1 applies for creating an object of a particular geometry. Typically, FDM 3D printed parts are made using a solid filament of various materials.

The filament is kept in the filament spool holder which is connected to the extruder and the nozzle system. In the extruder, the filament’s temperature is raised and brought near the glass transition temperature.

The melting filament is then allowed to flow through the nozzle system which lays it over the print bed according to the geometry of the part.

Cost of 3D printing a part using FDM or FFF 3D printing technology is lower compared to other technologies. This is because FDM does not make any use of some specialized source for cooling or solidifying the part as such as laser, UV light, or any other.

However, generally, the cost of 3D printing a part depends on various factors such as the level of infill required in the part, the geometry of the part, the filament material used to make it, and a lot more. So, it depends.

Print Quality
