The Complete Clay & Ceramic 3D Printer Buyer’s Guide
At 3DSourced we’ve covered everything 3D printing and 3D since 2017. Our team has interviewed the most innovative 3D printing experts, tested and reviewed more than 20 of the most popular 3D printers and 3D scanners to give our honest recommendations, and written more than 500 3D printing guides over the last 5 years.
Whereas most 3D printing involves plastics or metals, a growing area is in ceramic 3D printing, especially 3D printing clay. Ceramic 3D printers can create intricate and precise clay 3D models, including vases, bowls, plates and even medical instruments.
Now a fast-growing sector, ceramic 3D printing is predicted to become a $3.6bn industry by 2028, across 3D printed jewelry production, vases, 3D printed medical instruments, and even in aerospace.
This feature story covers how the ceramic 3D printing process works, the applications in each industry, and the available consumer and industrial clay 3D printers.
How ceramic 3D printing works
Ceramic 3D printers print “green” parts, unfinished clay parts that require post-print treatment, usually by firing them in a kiln.
Creating ceramic or porcelain 3D prints is the same as with standard plastic 3D printing, requiring a 3D model like an STL file or G-code. Ceramic 3D printers then print the part – the green object – with most clay 3D printing done through either FDM, Binder Jetting, Selective Laser Sintering or SLA 3D printers. Once printed, the part usually needs to be glazed and then fired in a kiln to give the part its finished properties.
You can 3D print ceramics using a variety of different 3D printing technologies, including:
FDM Clay 3D printing
Some specially-designed clay 3D printers – mostly delta 3D printers – can print ceramic materials with adapted extruders for these tougher materials. They extrude paste-like ceramics.
For example, Italian 3D printer manufacturer WASP’s clay 3D printer range, such as their Delta 2040, use air-compressed cylinders to extrude melted clay material using their Liquid Deposition Modeling (LDM) technology. As well as ceramic paste, the same technologies can print porcelain, aluminium, zirconium, and advanced ceramics.
Chinese manufacturer Cerambot have also released a number of low cost clay 3D printers. In addition to selling the printers, they have also developed custom ceramic extruders which can turn your standard desktop 3D printer into a ceramic printer. They claim this works well on printers such as the Prusa i3, and Ultimaker printers.
Binder Jetting Ceramic 3D printing
3D printer manufacturers such as Voxeljet offer Binder Jetting 3D printers to print accurate and large ceramics. Binder Jetting is favored for its ability to print ceramic parts with precise details, as well as not having any of the shrinkage during sintering associated with other forms of ceramic 3D printing.
Resin ceramic 3D printing: SLA / DLP
Resin 3D printers are not thought of as ceramic 3D printers, but Formlabs recently introduced a ceramic resin for use with their Form 3D printers. However, the resin is still considered experimental. 3DCeram also use DLP 3D printing methods within their industrial ceramic 3D printers.
Ceramic 3D printing applications
Currently, ceramic 3D prints are used in niche areas of automotive and aerospace production due to these parts’ light weight, strength, and temperature resistance in hot areas. Ceramic parts also have uses in aviation for their durability, such as in fuel nozzles.
In the future, it is thought that ceramic 3D printing applications will include medical implants, which can be made quickly and accurately on future ceramic SLA or DLP printers. Binder jetting is thought to be a good candidate for ceramic 3D printed prosthetics of the future.
Artists have also taken advantage of ceramic 3D printing and its boundless options to design some of the most beautiful 3D printed vases and other ceramics.
These include Oliver van Herpt, who has been involved in clay 3D printing since before it was easily accessible. Seeking a way to accurately create intricate ceramics, he found there were not any clay 3D printer extruders available at the time, and set out to create his own. Having designed his own custom clay 3D printer, he now creates some of the most precise and intricately detailed ceramics and has exhibits all across Europe.
How much do ceramic 3D printers cost?
Most ceramic 3D printers cost upwards of $10,000, and are reserved only for industrial applications and the construction industries. However, there are a few cheaper emerging clay 3D printers, some of which are very highly rated by hobbyists and makers worldwide.

- Company based: Italy
Fast and reliable.
Compatible with all major 3D slicers.
The clay and LDM extruders make for accurate and fast ceramic printing.
Post-processing of parts is difficult due to the enclosed print chamber.
Italian 3D printer manufacturer WASP make some of the fastest 3D printers in the world, and are known for high quality delta 3D printers, as well as for their entries into clay 3D printing. The Delta 2040 can print at speeds in excess of 300 mm/s, using WASP’s clay and LDM (Liquid Deposition Modeling) extruders for accurate and fast ceramic printing.
As well as their standard clays, the clay printer is versatile enough to print any soft paste material that can be extruded under 4-6 bar pressure. The printer uses a 1mm nozzle for precise clay 3D printing.
To get you started, the WASP 2040 comes with a small amount of white porcelain material that you can print with. The printer is compatible with all major 3D slicers, including Cura, Slic3r, and Simplify3D. WASP have a strong reputation for making workhorse 3D printers that print at phenomenal speeds, with the Delta 2040 no different.

Formlabs Form 3 with Ceramic Resin
- Price: $3,499 – Available on Dynamism here
- Build volume: 145 x 145 x 185 mm
- Company based: USA
Durable and precise.
Makes for precise ceramic 3D printing.
Not good for industrial-level ceramic production.
The Formlabs Form 3 builds on the Form 2’s success, with key durability and precision improvements that make it further stand out in SLA 3D printing. Originally released in 2018, Formlab’s Ceramic Resin allows you to 3D print fully ceramic parts that can be fired and turned into finished ceramics.
Originally brought out for the Form 2, these cartridges should be fully compatible with the Form 3, with the Ceramic Resin compatible with 50- and 100-micron print resolutions.
SLA 3D printers can print more intricate and accurate parts than delta FDM 3D prints will ever be capable of, so for experimental, precise ceramic 3D printing, this is a great option. However, Formlabs do state that this is an experimental resin, and that it has a lower print success rate than other Formlabs products, so consider this good for experimenting, but less suited to industrial-level ceramic production.
