With a small footprint, it offers individuals great ease of use, when working from home or having limited space. The machine will easily sit comfortably on your work desk, without occupying too much space.

Automatic Calibration

Unlike budget-friendly machines that aren’t equipped with automated bed leveling features, this one allows users to sit back and let the printer do the job. Its automatic calibration allows users to print right away, without engaging in machine adjustment every time printing a new model.

Dual extruder

With two extruders, users can print using different colors. In addition, one can also make use of soluble supports when printing with one color. This helps in creating finer details with a smoother surface finish.

Support for Multiple Filament

Although being a budget-friendly 3D printer, the Rostock Mini G2s works with an array of different filaments. You can use PLA, ABS, Nylon, PVA, and more. Hence, making it simpler for individuals to accomplish projects involving different needs.

Heated Print Bed

As you might expect, with support for flexible filament, the printer ensures strong bed adhesion by making use of a heated build plate. Its laser-cut aluminum and acrylic heated print bed helps in improving the overall quality of the 3D models.

The thoughtfully designed build plate creates a smooth surface. Therefore, enhancing accuracy as well as 3D printing speed.

High Extruder Temperature

Rostock Mini G2s is a versatile printer. It easily supports printing with stubborn materials such as Nylon and wood filaments. Thanks to its extruder that can withstand a temperature of about 240 degrees Celsius.

Upgraded Control System

The manufacturer of the machine has done an exemplary job of ensuring high-quality prints. By upgrading over a lot of features, the company has come up with this absolute precise 3D printer. And, one such notable upgrade is its newly designed control system.

With support for two extruders, the design eliminates the problem persisting with complicated wiring, often visible in its predecessors. Hence, saving a lot of space for printing.

Stand-Alone Printing

Using the SD card, users do not need to connect the printer with a desktop throughout the printing process. On the contrary, the Rostock Mini G2S can work as a stand-alone device.

Enhanced Speed along with Positioning Accuracy

The main advantages of delta 3D printers, in general, are high-speed printing coupled with precise positioning. Using the lightweight print head which is driven by three motors, these printers allow for faster extruder movements.

And, Rostock Mini G2S with speedier steppers and controller, has taken the print speed to an altogether new level. Also, you will experience highly accurate positioning at the center of the print bed. All of these perks ensure high-quality 3D printing, and at a much faster rate.

Robust Design

With a sturdy body and robust design, this 3D printer is able to print without vibrations, even at a higher speed. Hence, offering users accurate models.

First Impressions

Geeetech Delta Rostock Mini G2s

The printer looks very much similar to the usual delta 3D printers. Safely snuggled inside the package, the Rostock Mini G2s comes as a kit. The different components are perfectly labeled and separately wrapped for secure delivery.

After assembly, the machine stands tall with filament holders on the top, feeding the two different extruders. In addition, with an upgraded LCD control panel, now it is possible to complete printer settings in no time. One can have an eye on the real-time progress of the 3D projects. Thanks to the intuitive control panel that provides entire details with ease.


Unlike plug-and-play design, a kit needs a lot of effort for completing the setup. From verifying if all the components are present in the shipped package to final cable tidying, you will require a lot of work before starting to print.

Do not forget to read the complete assembly manual before you start putting the components together, even if you have prior experience of working with DIY kits. You can also check the photos available in the manual for a better understanding of the build process.

Remember, you will be handing a lot of small pieces throughout the assembly. So, keep a white plate or cloth handy to hold all the tiny components. This way, you won’t miss any piece, necessary to complete the assembly.

Also, you will rarely require too much pressure for adjusting screws and bolts. Ensure to read the assembly tips carefully, or else, the extra force can lead to broken parts. For instance, over-tightening the M3 square nuts can break the acrylic.

Those finding it difficult to fully seat the acrylic pieces into its socket, can lightly sand the socket as well as the corners of those pieces and make sure these fit correctly and tightly.

Printing Type/Cost

Geeetech Delta Rostock Mini G2s specs

Rostock Mini G2s 3D printer is based on FDM technology. In this printing process, the extruder heats the filament above the melting point to deposit it on the build plate.

Each time, one layer is deposited and is let to cool partially. Later, the bed moves and prepares the space for the next layer. This process repeats until the complete model is prepared.

FDM technology is the most accessible of all AM processes. In addition, it is also simpler to learn and accomplish.

When it comes to the printing cost, making objects on an FDM 3D printer happens to be cheaper when compared to other 3D printing technologies. However, you must consider the different variables that constitute the overall cost of the parts. For instance, the filament cost, amount of filament used, part infill, layer height, and more.

Print Quality
