Spitfire System

Configurable and fast extruders by WASP

Extractable cartridge
with a simple turn of screw

The idea behind the new Spitfire System is to simply extract and replace a cartridge (consisting of nozzle, barrel and coupler) with a simple spin of screw, depending on the different printing needs and on the materials you want to print.

The New Spitfire System

The innovative WASP Spitfire System leads to a whole new generation of extruders: the modular architecture allows to mount a specific cartridge and nozzle for what’s your need. Decide what you want to print, we give you the right extruder.
Spitfire takes its name from the famous Second World War airplane. It’s an innovative system, that throught several configurations, allows to reply to the several printing needs.
It’s a guarantee of high quality and sturdy printed pieces, it can be heated up to a 350°C temperature and according to the several needs it can be assembled in 3 different sizes: 0,4; 0,7; 1,2 mm. All the exchange or configuration operations are safe and quick thanks to the Spitfire System.

The cartridge (consisting of nozzle, barrel and coupler) is the heart of the Spitfire System and gives the new WASP extrusion system maximum modularity and versatility. From now on, the extruder can be configurable, depending on the different printing needs.

Two different steel cartridges: Spitfire Core LT (cartridge with teflon) for low temperature prints, Spitfire Core HT  (cartridge without teflon) for high temperature prints. To gain long lasting extruders and minimize frictions.

0.4 / 0.7 / 1.2 mm, three nozzle sizes on the same extruder each for a specific need.

Essential and Clean, ZEN Extruder, Double Extruder by WASP


The fast and clean dual extruder

ZEN Extruder is the solution for a faster and accurate double extrusion 3D print. Featuring the configurable Spitfire system and a totally mechanical basculating switch it just condenses all the best of WASP technology.

ZEN EXTRUDER, all the features of the new double extruder by WASP


The exchange system between an extruder and the other is mechanically performed without the need for additional servomechanisms through a variable height tilting solution for a faster and more reliable printing.


The innovative anti-drip flap, when the second extruder is activated, immediately cleans the nozzle that is deactivated without requiring the whole extrusion system to move to the perimeter of the print surface at each extruder change, to allow the dripping of molten material inside the just used nozzle. This innovative solution allows significant time savings during the whole printing process.


Each of the two extruders implements the new configurable Spitfire system, giving you the possibilty to set your cartridge and nozzle at the best for every material.


Mount different nozzles to print with different resolutions at the same time.


The two different cartridges allow to print different materials with different temperatures at the same time.


ZEN extruder is compatible with DeltaWASP 40 70 Industrial and DeltaWASP 20 40 Turbo2.


Led by the new generation boards, ZEN Double Extruder can be attributed to materials with different melting temperature or different drop diameters. ZEN Extruder can be adjusted on DeltaWASP 20 40 Turbo2  and DeltaWASP40 70 Industrial.

Experimental 3D printing architecture

Trabeculae Pavilion at Made Expo 2017


Politecnico di Milano presents a preview of Trabeculae Pavilion at Made Expo 2017, an experimental architecture which fuses 3D Printing with biomimetic research. From the 8th until the 11th of March, within the BSmart! area, in Pavilion 10 of Fiera Milano-Rho, will be introduced an innovative prototype of lightweight architecture which demonstrates the revolutionary potential of computational design and 3D printing for constructions. The project is the synthesis of a research concentrated on the use of Additive Manufacturing to provide novel solutions to the emergent necessity for a reduction in the exploitation of material resources.


New additive manufacturing techniques

The pavilion is a full-scale demonstrator entirely 3D printed with a high-resistance biopolymer developed together with industrial partner Filoalfa, in order to elevate Fused Deposition Modelling (FDM) to construction purposes. The fabrication process of the building components is based on a printing farm of WASP Delta printers (Delta WASP 4070 e Delta WASP 60100), capable of delivering high accuracy within a continuous production process. The use of the new SPITFIRE extruder  is introduced to shape stiff components within a minimized amount of time. The synergy of design, material and manufacturing technologies allowed the conceptualization of an innovative construction technique based on an additive process which builds architectural forms conceived with a load-responsive material organization.


The pavilion is fabricated by ACTLAB - Politecnico di Milano with a production center based on a printer farm of WASP delta robots


The building components are printed with the new SPITFIRE extruder and realized with a high-performance biopolymer developed with Filoalfa

Advanced and efficient architecture

“The last decades have witnessed an exponential growth in the demand of raw materials due to the rapid industrialization of emerging economies and the high consumption of materials. This research looks at biological models and the opportunities offered by the new additive production technologies in order to find sustainable solutions to the exploitation of materials. Our objective is to explore a new type of non-standard architecture: advanced, efficient and sustainable,” declare Roberto Naboni, architect and researcher at Politecnico di Milano, and Ingrid Paoletti, Associate Professor in Building Technology at Politecnico di Milano. “We looked into Nature to understand how lightweight and resistant structures work with a minimized material use. Studying the internal bone microstructure, we have created algorithms which allow us to generate three dimensional cellular structures, varying in topology and sizing, with the precision of a tenth of millimeter”


The cellular structure of the pavilion varies in porosity, orientation and topology to enhance its mechanical behaviour, Following the role model of the internal bone microstructure.

Component generated live at Made Expo

At Made Expo 2017 will be presented the interdisciplinary research process which involved the fields of computational design, biomimetics, advanced manufacturing and material engineering. A full-scale prototype of lightweight skin system will be exhibited accompanied by a production centre with 3D printers generating live the components of the Trabeculae Pavilion, which will be subsequently completed and exposed at Politecnico di Milano.

WASP launches the new professional clay extruder


LDM (liquid deposit modeling) Wasp Extruder is the name of the new extruder for ceramic materials that can be adapted to most of the 3D printers on the market.

WASP’s work has always been focused on the development of systems that allow the use of functional materials like ceramics, porcelain, clay, alumine, zirconium and advanced ceramics, in order to promote digital handicraft and self-production. By launching this new product the group aims to promote the print of fluid-dense materials and advanced ceramics in the world.

In two years of time and after experimenting all the possible combinations of pressure, nozzles and materials WASP has created a model of extruder which is able to interrupt and restart the extrusion flow.

The new LDM Wasp Extruder  can reach a level of precision which is very close to that of plastic polymers extruders thanks to the combination of a screw extruder and a pressure extruder. With this technology it is possible to control with accuracy the flow of material and also to use retraction to interrupt deposition.


-Bubble eliminating extruder, it eliminates air bubbles in the mixture

-Extrusion controlling system with retraction option

-Outward pressure multiplier until 40 bar in the screw extruder

The new WASP Clay Kit includes a 3 kg tank, which can be substituted with a 15 kg one, on demand. The preceding needle experimental models did not allow middle size printing because of the limited amount of mixture they could contain. The tank can be refilled or cleaned simply by opening the caps located at the extremes. Inside, there is a piston with two 4 bar gaskets which pushes the material through the teflon pipe (diameter 12mm) which supplies the extruder. The cap located on the back has a safety valve set at 8 bar.

On the stand of the tank there is a pressure regulator and a return preventing valve. Inside the chamber, the material is funneled toward a screw which pushes it out producing a pressure of 40 bar without damaging the system. It would be impossible to reach such a pressure level with a common pressure extruder. This technology allows the air to outflow upward , eliminating the probability of finding bubbles inside the mixture. Like for a common pressure extruder, if there were bubbles the flow would be interrupted and the print would be damaged. Furthermore, thanks to the screw, the density of the printing materials is higher. This allows to reduce the time for their change of state, from liquid to solid, thus eliminating the risk of collapse of the printed object. In case the screw or the chamber were damaged they can be easily substituted.

Adaptability to other machines

The set was created to be installed on WASP printers, but can be adapted to most of the existing machines. It is very easy to install LDM Wasp Extruder on other machines. Firstly, it is necessary to print the supporting cover (the source files are provided by WASP). Secondly, the extruder must be linked to the wire and the “number of steps per millimeter” must be set to 400.

This configurations are provided by the most common slicing softwares, like Slic3r or Cura.
