What delivery service will you use?

To reduce the waiting time and improve the user experience for our users, we have been working with reputable logistics companies such as FEDEX, UPS and DHL. For this campaign, depending on backers’ countries, we will use different shipping carriers for faster and safer logistics services.

What program we would use to design the pot and how that interacts with the ceramic 3D printer?
Eazao is very suitable for making ceramic products such as flower pots. You can use 3D modeling software such as fusion 360 (there is a free version), as long as they can export to STL format.
 
First, you need to use 3D modeling software to generate the model, then import the model into Cura (free) slicing software to generate gcode code, then import the gcode code into the SD card, and finally put the SD card into the printer to work.
 
What software can I use?
Modeling software: Fusion 360, 123D, Meshmixer, SolidWorks

Slice software: Cura, Slic3r
Other software: Repetier host, Notepad++

What is the correct viscosity of the clay slurry? How do you check it?

The hardness of the clay obtained from different sources is different, so it is necessary to add water to make it soft. Usually, you need to add about 12% by weight of water to the clay. Of course, you can also add ethanol. The evaporation of ethanol helps the model to dry. It can be compared with the softness of toothpaste by contrast method, such as crest toothpaste, clay. It needs to be harder than toothpaste.

 
How long must the print remain on the bed before it can be removed?

It can be taken out immediately after printing. For some thin-walled models, you can use hot air heater to helps the model to dry more quickly.

 
Is a kiln required? Or will a regular kitchen oven do (for some clays)?

For ordinary clay, it needs to be fired in the kiln. The temperature depends on your needs. Generally, the pottery needs about 800 °C, and the porcelain needs about 1200 °C.

We have developed a kiln using a regular kitchen oven, allowing you to burn ceramics at home. The microwave kiln developed by us can heat up to over 1000℃ in about half an hour, the longer the temperature, the higher the temperature.

 
What bed surface is used? What alternatives are recommended?

The printed model is directly on a square wooden board of 170 mm*170mm.

 
Warranty of Eazao.

The warranty period is 180 days. As for the quality issues (non-human damage) of your Eazao during the warranty period, we provide replacement parts free of charge. Customers only need to pay the shipment fee. If the quality issues are caused due to improper use or beyond the warranty period, the replacement part and shipment will be charged from customers’ side. Since Eazao is a modular design, the shipping fee will be relatively less and is also a money saver.

What type of food can Eazao print?

We do not recommend printing food. The main materials of Eazao are PVC, nylon and  stainless steel. It can print any food paste with the correct viscosity and no hard, sticky or fibrous.

 
Is it safe to print with clay?

Printing with clay is safe. The clay you use is no different from the materials used in ceramic  stores around the world.

 
What is the accuracy or resolution of the printer?

The best practice is a ratio of 1 to 2, and a layer height of 0.8 mm is best printed with a 1.6 mm nozzle. With our 0.6 mm nozzle, very fine and soft clay can be as low as 0.3 mm per layer.

The best result is a layer height between 0.4 and 1.5 mm and a larger nozzle. However, the printout is still clay and will deform when dry. Solid or multi-walls are not recommended unless a large degree of stability or heavy post-processing (such as engraving) is required.

For better printing parameters, we can’t provide much advice and still need to explore the necessary printing techniques.

How fast can Eazao print?

The print speed depends on many variables:

The type of clay you use.
The hardness of the clay.
The height and line width you have chosen.
Printed model.

For any layer height or nozzle width, the best printing speed is 15 to 25 mm per second.

What materials can I print?

We recommend using clay to print, but as long as they are smooth and free of particles or fibers, you can print almost any viscous fluid. Any clay can be used with the Eazao extruder. After the clay is mixed, it is necessary to mix the printed shape with water according to the nozzle size. You can use a wide variety of clay blends while using a hair dryer for accelerated drying while printing.

We offer standard clay mud powder. The clay mud powder is ground from high white mud. The quality ratio of clay and water: clay: water = 100:25 (±3).

What is it the voltage currently running?

The printer’s operating voltage is DC 12V 10A.

 
Is your hardware open source?

You can adjust and modify our printer as needed. Its CPU is based on the open source Arduino mega + ramps 1.4 setup. However, in this case we are unable to provide a wide warranty. We have opened some of the source code and can download it from here.

If I forgot to clean the extruder, now it is stuck?

Disconnect the extruder from the printer and place it in a glass filled with water.
Make sure it is not submerged in the middle of the flexible coupling under the motor and gearbox! Let it soak for about an hour.

 
How to clean and maintain the extruder?
Follow the steps below to fully repair the extruder. If it only needs some clay or some hardware  needs to be removed, just brush with water.
 
How to maintain Eazao?
As with any machine, it is best to clean your Eazao after each print. Use a damp cloth to remove the clay from the base, aluminum and steel parts. You need to clean and lubricate the linear guides. At the same time, the belt is still tight every month and the dust and clay on the rails are removed.
