Crazy3DPrint CZ-300 review – useful tips for choosing electronics


The Crazy3DPrint CZ-300 is undeniably a cheap 3D printer, but with decent specs and a huge 300x300x300mm build platform, it’s worth it.

There are a lot of printers at this price and I have checked quite a few. The only feature that seems to be compatible with everything in this price range is the construction and the basic features.

3D printers in this price range are usually based on designs and software available for free, then mass produced to make them cheap.

It’s basically the CZ-300, but what stands out is the amount of extra work the company has done. Crazy3DPrint has taken care to ensure that if the feature set is basic, it is balanced with decent pieces, and investments have been made in the places where it matters; including the control panel and hotend.

It’s no surprise that buying the CZ-300 is cheaper than buying the parts to build your own 3D printer, and of course, you don’t have to bother to understand how all of these parts go together .

Design

Like almost all FFF (Fused Filament Fabrication) 3D printers, the CZ-300 is a Cartesian type, with moving axes X, Y and Z.

For home use, this means that if something goes wrong it is usually quick and easy to fix.

The design of the printer is simplistic with linear extruded aluminum rails with a basic T-slot forming the frame. Everything is bolted to that with brackets and plates giving it a real look and feel of DIY, even if it isn’t.

This printer style reflects the open-source community. It will appeal to anyone who wants to learn how a basic 3D printer works but does not want to spend hours or even days building one from a kit, or who wants to spend too much money.

Almost all components, from motors to belts, are exposed, although a nice touch of Crazy3DPrint is that all cables are neatly stored inside the cable storage and the power unit is contained in a case appropriate command.

In terms of design for such a simple 3D printer, the use, maintenance and security of the printer have been well thought out. It is one of the few printers at this price that comes with CE, LVD and FCC safety certificates.

features

3D printers have evolved, and at the TCT 2019 show at the NEC, the latest batch of consumers, as well as industrial printers, were on display.

There have been many innovations; even simple 3D printers were starting to offer some of the more advanced capabilities such as automatic platform leveling and filament recognition.

The CZ-300, however, gets back to basics but impresses in other ways.

The printer has one of the largest print areas of all printers at this price at 300x300x300 mm and offers a layer resolution of 0.1-0.4 mm with an X / Y alignment accuracy of 0 , 0125 mm.

Technical sheet

These are the full specifications of the Crazy3DPrint CZ-300:

Construction volume: 300x300x300mm

Memory: SD card

Nozzle size: 0.4 mm

Layer height: 0.1 – 0.4 mm

Bed: Heated

Printing area: Glass

Software: Cura / Slic3r

Materials: Multi-material support

Material included: PLA

AC input voltage range: 100 ~ 120V / 200 ~ 240VAC; 115V / 230

The large print size means that the size of the printer is considerable. However, due to the open design of the frame, the printer does not appear so large.

The external dimensions are 534x503x582mm, which means that it sits roughly on a standard work surface of 600mm, but it is waterproof. You should also consider that the control box is located outside the main printer.

In terms of weight, surprisingly, despite the size, the machine weighs 14.5 kg, which, all things considered, is not much.

The CZ-300 has broad print compatibility supporting PLA, ABS, PETG and many other materials as standard. It uses a 1.75 mm filament as standard.

Material compatibility is essential and should top the list when it comes to purchasing considerations.

What sets the CZ-300 apart is that it goes beyond many other inexpensive 3D printers by offering you options.

In addition to the standard printhead, you can purchase a second printhead designed for specialty materials such as carbon fiber PLA and metallic PLA.

The design of the print head is very neat with a quick release head which allows you to exchange the standard head for the specialized head.

While removing the machine head can be done in seconds, rewiring takes about five minutes. The process is simple and should not be too much of a problem for someone who has just started as there is no solder involved.

The hotend also allows you to exchange the nozzles from brass to steel according to your preferences.

The standard nozzle is a 0.4 mm with a maximum temperature of 260º.

Crazy3DPrint has also made some effort to provide a list of spare parts for the machine, so if something goes wrong in the future, then everything you need to repair and possibly upgrade the machine is available on crazy3DPrint’s website.

The controller card allows several ways to transfer gcode to the printer; SD or USB.

As the basic configuration is open source, it is fully compatible with Mac OS, Windows and Linux, although the profiles provided are only for PC.

Another important feature of the CZ-300 is that it has passed all the safety certificates of CE, LVD and FFC.

Configuration overview

When the printer arrives, everything is carefully packed, and using a printed instruction sheet, it takes about 20 minutes to bolt together.

The majority of the construction was done for you, so it is not a difficult task, but some of the images in the instructions are not as clear as they could have been.

Once everything is tight, it’s time to power up.

After a short boot sequence, the ready-to-use printers and Crazy3DPrint include a preloaded SD card with a selection of models to help you get started.

The first thing to do before printing is to pass the filament through the system. This is a manual task as there is no automatic charger. A metal level on the side of the extruder allows you to pass the filament through the system until it reaches the print head.

The Crazy3DPrint provision profiles for the PC version of CURA and Slic3r, Mac and Linux users will have to fend for themselves, but in applications and Simplify3D, this process was not complicated.

Once you’ve selected your software, it’s time to calibrate the machine; the most important process is the leveling of the bed. It’s quite simple with the hotend moving to the four corners of the platform so that you can adjust the height using the screws under the bed.

Ensuring that the bed level is perfect is essential to the success of this printer. Placing a thin sheet of paper between the nozzle and the bed and making sure there is a little drag ensures that the print head is at the correct height.

Too high and the filament will not stick to the bed, too low and the filament can go up in the head, which can be a real problem.

When finished, you are ready to print.
