FAQ

General questions


#01. What materials can I print with?

While we recommend to print with stoneware clay, you can print virtually all clay pastes as long as they are smooth and without particles or fibers. We are testing a system that can handle grogged (chamotte) clay but for now its not reliable enough for commercial use.

More information on clay can be found here

#02. Is there any pre or post processing possible?

All Pre and Post processing follow the standard pottery process. After printing you can still shape or work the clay like any other conventional produced work

#03. How fast can I print?

Printspeed depends on many variables:

- the type of clay you use.
- the softness (viscosity) of the clay.
- layer width and height you choose.
- the design of the print.

Best printspeeds are between 15 and 20 mm per second for any layer height or nozzle width

#04. What the precision or resolution of the printer?

Best practice is a ratio of 1 to 3, 1mm layer height is best print with a 3mm nozzle.
Very fine and soft clay can go as low as 0.4mm layer with our 0.8mm nozzle.
Best results are with layer heights between 0.5 and 1.5mm and larger nozles. However, the print output is still clay and will deform while drying. Solid or multiple layered walls are not recommended unless there is a large degree of stability or heavy postprocessing (like sculpting) needed.

#05. Does the printer come with a warrenty?

Our warranty covers mechanical and electronic parts only. You can find more information about this topic in the sales condition you receive with our pro-forma, invoice or quote

#06. Is it safe to print with clay?

Printing with clay is safe. There is no difference to the clay you print with and the material used in any potter shop around the world. However, always keep your safety in mind when using dry clay powder, compressed air and glazes.

#07. Is there a web shop?

Yes we have LUTUM® Store !

#08. Do you have a reseller in my country?

We do not work with resellers, That way we can keep our prices relatively low.
To see one in action locally check with us and we might be able to connect you with someone near you.

Techincal questions


#01. Is there a maintenance schedule?

Yes, there is, you will receive it with your printer.
As any machine, it's best to clean your LUTUM® after every print day. Use a damp cloth to remove clay from he base, aluminium and steel parts.
Grease any of the guides and rails after cleaning.
Every month or so check of the belts are still tight, clean and grease the Spindle and nut and remove dust and clay between the rear rails.

not good.

#02. What material is the printer made of?

The printer base is made of CNC cut melamine coated plywood, this material is one of the few materials that can withstand exposure to clay and gypsum (plaster).
Aluminium is used for the moving parts as the low weight ratio per part is essential.
The extruder parts are 3D printed steel or (gold plated) cast bronze for the high end models. Our cartridges are made from Pressure grade PVC.

#03. Why is the LUTUM® DUAL an experimental machine and what does that mean if I purchase it?

Dual color printing with wet clay is difficult and we do not have the time to experiment lots with this setup. Therefor we can't advice much and the print technique necessary still need to be explored.
It's experimental

#04. Is your hardware opensource?

You can adjust and tinker with our printer as much as you like. It's CPU is based on the opensource Arduino mega + ramps 1.4 setup. Unfortunately we cant give extensive warranty in such cases

#05. What current does it run on?

The printer uses a standard PSU working with voltages between 110 and 250V and 50 to 60Hz
For peripherals like the ultrasonic cleaner or the compressor we need to know what your local current is.

#06. What more do I need after I have the LUTUM® installed?

If you are going to use our printer to print clay it's advisable to setup a small pottery workshop around it.
You will need compressed air, and a potters kiln the size of your build volume. If you plan on high production volumes it wise to obtain a pugmill to fill cartridges. A wet and and drying area is also advisable.

3dPrinting Food


#01. Is it possible to print Food with the LUTUM® 3dprinter?

While it's possible to print food with our regular extruder we advice to use the brass or gold plated variant with our special food Auger.

#02. What types of foodstuff can I print with?

Any foodpaste with the correct viscosity and without hard , stringy or fibrous bits can be printed.

#03. Why is the food printer not on sale in your web store?

When attaching the gold extruder on our standard LUTUM® you can print food. Extensions like a heated extruder barrel are available on request

#04. Where can I order one?

You can order via our LUTUM® STORE or send us an email with your particular request.

#04. How about hygiene and safety?

While it's safe to use our printer with various food pastes, its not a food grade machine and can only be used for experimental and demonstrational purposes. we do not advise to use our standard clay extruder as the material used for that is slightly porous. Food particles could remain in the material and pose serious safety risks.
Our brass and gold plated extruders are food safe but must be cleaned thoroughly before and after use. We advise to use our sonic cleaner along for cleaning.
The PVC we use to construct the microcartridges is food grade and safe to use.
