About WASP

WASP stands for World's Advanced Saving Project. The company was founded in 2012 by Massimo Moretti, an electronic technician with more than 20 years of experience in open-source product development. WASP is a bold experiment where science, economy, and politics are intertwined in order to add economic value to useful knowledge, reinforce social responsibility, and establish equal opportunities for everyone.


The WASP team is going to invest the revenue obtained from the selling of 3D printing machines in projects that aim to spread advanced technologies all over the world and make them accessible to everyone.

"We're not so crazy to think we can save the world, but we're crazy enough to work for it”, — Massimo Moretti, the CEO of WASP.



Product line


Delta WASP 40100 Clay


In 2018, the company’s product line was replenished with a brand new model — Delta WASP 40100 Clay. The device creates objects using WASP’s proprietary technology called LDM (Liquid Deposition Modeling). One of its undeniable advantages is that the technology can be easily adapted for most 3D printers currently available on the market. WASP has always strived for developing optimal solutions for digital 3D printing systems that use ceramics (including polymeric and zirconium), clay, porcelain, and aluminum. After two years of research, WASP has finally created an outstanding extruder model with the ability to abort and restart the extrusion of such difficult materials in an extremely accurate way.

The material under pressure is delivered to the print head and then extruded with the help of a transport screw from a stepper motor. Since the printing bed doesn’t move, no vibrations occur during the printing process, and the piece is not subject to deformation.


The Delta WASP 40100 Clay prints with various materials including porcelain, ceramics, refractory materials, clay, and many others. The print volume is impressive — Ø 400 mm × h 1000 mm. The accuracy of the finished parts is also great, while the layer height starts from 0.5 mm.

The WASP Clay is equipped with a 3 L (0.8 gal) tank which can be replaced with a 5 L (1 gal) one. The tank can be easily refilled or cleaned by opening two caps located on the top. Inside the container, the piston with two gaskets creates the pressure of 4 bar (58 psi) and pushes the material down the 12 mm (0.5 in.) teflon pipe. On the back of the tank, there is another cap with a safety valve set at 8 bar (116 psi).


The device is made of aluminum and steel, ensuring stability and accuracy even when printing with exceptionally dense materials. The configuration provides the maximum printing speed of 150 mm/s. The standard nozzle diameters are 1.2 and 2 mm, which can be altered to 4, 6, and 8 mm with an optional LDM WASP Extruder XL 3.0.


Useful features

The Delta WASP 40100 Clay boasts a handy feature — a recovery system called Resurrection. This function easily resumes the printing process if the device shuts down due to a sudden blackout, for example. The extrusion data is saved on the SD card in the "resurrection.g" file, which allows the user to resume printing once the printer is turned back on.

If the Resurrection system has failed, or you are not satisfied with the final result after resuming the printing process, there is the Free Zed function. It allows for the launch of printing from a certain height, specified in millimeters (along the Z-axis). After you’ve set the height, the printer is waiting, while the printing process is shown on the display, until the set height is reached — and the extruder resumes printing.


Unlike the previous model, the Delta WASP 2040 Clay, the Delta WASP 40100 Clay allows printing on a removable printing platform made from stainless steel, or even directly on the floor. Once the part is finished, you can continue printing without waiting for it to dry, simply by moving the printer from one platform to another, or by replacing the platform.

If the 5L (1.3 gal) material supply tank is topped up, the operation time of an hour and a half is guaranteed while printing with a 4 mm extruder.

Printer setup

Since the printer is delivered fully assembled, you will not have to tinker with a preliminary setup. If you are planning to print on the original printing platform, you will need to run calibration before the first use. If you want to use a printing platform of another manufacturer, you will have to adjust the height along the Z-axis to match the thickness of the platform.



You can use any available slicers to work with the printer, including Cura, Slic3r, or Simplify3D. The printer supports .stl, .obj, .gcode file formats. You can use an SD card to import the finished g-code to the 3D printer's memory to reproduce a piece in standalone mode.




Cura is one of the most popular slicing software solutions for 3D printing. Even though it is currently owned by Ultimaker, the platform remains open-source and can be accessed with LGPLv3 license.

Use cases

“Ikebana Rock'n'Roll”: a collection of 3D-printed ceramic vases from a famous sculptor Andrea Salvatori


Andrea Salvatori is a virtuoso of contemporary ceramic art. Representing Italian informalism and abstractionism, the master presented a number of various ikebana vases during his personal “Ikebana Rock'n'Roll” exhibition held in New York from April to May, 2019. Every piece of art was printed with the Delta WASP 40100 Clay.


Andrea explains: “The search for balance between all the elements also passes through the container. There are numerous schools of Ikebana and each one opts for a particular arrangement. Some use tall vases and vertical lines, others use shallow containers. I decided to add digital technologies into the mix”.



Salvatori created a number of asymmetrical masterpieces for the exhibition. The vases were encrusted with pink-colored spheres of various shades that represent musical notes, highlighting Eastern spirituality and the calmness of nature combined. In order to create compositions of astonishing beauty, the artist uses flowers, branches and other natural elements.
