Review: Sainsmart Coreception 300 – Everything You Need To Know

The Sainsmart Coreception 300 is a welcome new CoreXY-style 3D printer from the Chinese company who are well-known for their high-spec budget models.

CoreXY 3D Printers are popular amongst enthusiasts, as they can offer faster print speeds and are simpler, some would say, a more elegant design where the bed only moves in Z and all the motors remain stationary. This can allow a large print volume in a smaller overall frame size and more accurate prints as the weight of the motor isn’t being moved around.

The Coreception (I’m pretty sure it’s supposed to be pronounced Core-ception, not co-reception!) offers an array of features in addition to its CoreXY design.

To keep bedroom users happy, it features a color-changing RGB LED lighting feature that allows you to remotely control 7 colors as 3 patterns of in-built LED lighting.

The Sainsmart Coreception 300 is designed to offer you excellent value for money. It’s an ideal choice for creators or hobbyists who want a large volume printer.

In this post, I’ll be looking at some of its key features, its overall quality, and any things that may make it unsuitable for your application. In the end I hope you will be able to decide whether the Corecption 300 is the right 3D printer for you.

The Sainsmart Coreception 300 comes loaded with most of the features you could reasonably need, each designed to help you maximize the benefits of this 3D printer. Here are some of the more notable highlights:

  • Large build volume, measuring 300 mm x 300 mm x 330 mm. This makes it ideal for printing relatively large objects like cosplay or gaming terrain with ease.
  • The printer also comes equipped with innovative CoreXY architecture. The design features a 370 mm linear guide, a 350 mm Y-axis, and a double Z-axis. This innovative frame structure enhances print stability and quality significantly.
  • The Sainsmart Coreception 300 also got an upgrade in its height. As a result, the printer is capable of printing objects as high as 13 inches without any issues.
  • The innovative design allows creators to print a wide variety of objects, making the unit the perfect choice for professionals and hobbyists.
  • The Coreception 300 also has an auto-resume feature. The feature protects you from any interruptions in printing and ensures you can resume right where you were in case the printing is stopped abruptly by a power outage.
  • The unit also features a customized TMC2208 silent module that makes the printer one of the quieter units in its category.
  • The printer can support various types of filament thanks to its direct drive feeding design. The design also enhances print speed while maintaining high levels of accuracy and print quality.
  • The Sainsmart Coreception 300 comes with an upgraded extrusion nozzle that offers excellent heat dissipation, smooth discharge, and fast heating.  The hotbed will easily reach up to 100 Degrees in Maximum Temperature in a matter of minutes.
  • The Sainsmart Coreception 300 is partly assembled from the factory. The manufacturer offers a simple assembly kit that allows users to assemble the unit in less than 15 minutes.
  • The unit also features RGB LED lights attached for aesthetic purposes. The lights offer 3 different modes including monochrome, flashing, and speed control. The lights offer up to seven different colors and they add a little fun in the whole printing process.
  • The Sainsmart Coreception 300 also offers an improved carbon crystal glass platform. The platform is far more durable, easier to use, and offers excellent print accuracy.
  • You also get a 3.5 inch HD Touch screen to control the printer and its operation. The screen feels intuitive and highly interactive as well.


  • Comes with a relatively large build volume that offers excellent versatility in printing
  • The unit is partly assembled making it easier to set up for the first time
  • Can support different types of filament materials including ABS, PLA, TPU, and others 
  • Features an auto-resume printing feature that protects you against abrupt interruptions in printing
  • Silent operation thanks to its customized TMC 2208 Modules


  • The user manuals provided by the manufacturer are too technical for some people to follow
  • Users have also had issues getting the source code for the Marlin Open Source firmware used by the printer
  • Does not have an auto-leveling feature for the bed, which may be an issue for some people

Unboxing and Box Content

The Sainsmart Coreception 300 is shipped in a sleek and durable package that should be easy to open once the product arrives. The manufacturer also includes a few things in the box for you. First, you will get the printer. Secondly, there will be an assortment of tools, all of which will be needed to assemble the printer and set it up for first-time use.


The Sainsmart Coreception 300 comes partly assembled from the factory. The manufacturer says that it should take fifteen minutes to get the printer up and running. Most experienced users seem to have an easy time based on the reviews we saw on Amazon but there were several challenges pointed out.

First of all, the setup manual provided by the manufacturer is too technical. A beginner would have a hard time getting past it. There is also no information on the user guide on extruder assembly. We also did not see any guidance on using the filament detector.

While it’s possible to set up the printer in 15 minutes as suggested by the manufacturer, if you are new to 3D printing or perhaps you are not the handiest person out there, it may take relatively longer to get the unit up and running.


As for the slicers, the printer can use an array of slicing software solutions. It ships with an outdated version of Cura, but you can easily download the latest version from the Cura website for free. CURA and Simplify3D are however some of the more commonly used slicers that are compatible with the Coreception. In terms of Firmware, the Coreception uses Marlin running on an MKS Robin Nano board.

In Use

In general, the experience of users using the Sainsmart Coreception 300 has been quite good. The printer is relatively fast when it comes to printing speeds compared to other printers in its category due to its CoreXY design. Additionally, the printer is also very quiet, making it an ideal choice for bedroom use or classrooms. As you’d expect from a CoreXY, the stability of the prints and lack of associated artifacts in your prints is excellent.  

The Sainsmart Coreception 300 is very stable and it’s no surprise based on its sturdy construction and innovative structure. Additionally, the print quality looks great. But one thing that sets this unit apart from other printers in its category is the relatively large build volume and height. This simply means that the Sainsmart Coreception 300 can print a wide range of objects, including larger and taller ones like cosplay helmets or gaming terrain.


The Sainsmart Coreception 300 is a solid 3D printer that offers excellent value for money. It features an innovative construction, designed to enhance durability and print stability. The printer is quick and relatively quieter compared to other units in its category.

I also loved the large build volume which makes the Sainsmart Coreception 300 an ideal choice for people wishing to print larger objects.  Additionally, the unit also features an auto-resume feature to guard against interruptions in printing and can support multiple filament materials as well. 

The Sainsmart Coreception 300 is quite a large 3D printer. You will need a lot of floor or countertop space to place it. You don’t also get an auto-leveling feature for the bed, which can be an issue for some people but personally I wouldn’t let this put you off as auto-leveling is never as reliable as it sounds!

Overall, the Sainsmart Coreception 300 remains a solid 3D printing unit. It offers an array of features for a very affordable price and is especially worth it if you’ve been looking out for a budget CoreXY 3D printer. Overall it’s highly recommended!
