DELTAWASP 3D Printer Review: Ducati DELTA 3D Printer

By | June 6, 2021

Any 3D printer is a construction robot, but any 3D printer, regardless of the technology involved, looks more like a bot built using the Delta architecture. The first Delta 3D printer I’ve had the opportunity to test and play with for a while is the DeltaWASP 20×40, manufactured by Imola, Bologna-based WASP.

This is the company whose founder, Massimo Moretti, is working on a giant, 12-meter Delta 3D printer capable of building small, earthy, habitable structures.

And, apparently, all the challenges it faced when tackling this extra-large project have paid off in the smaller Delta machines produced by WASP: both because by selling the smaller machines it is funding its dream and Because the DeltaWASP 2040 really makes 3D printing small objects seem as easy as children’s play.

The numbers in the printer’s name represent the size of its manufacturing volume: a cylinder with a diameter of 20 cm and a height of 40 cm. I have to admit that I haven’t tested this machine to its full potential, but since I went to pick it up at WASP’s factory, it’s practically non-stop 3D printing. And, apart from a few errors in Cura’s automatic support settings and some difficulties 3D printing large parts into flexible filament, it’s never given me any problems.

Since I organized a 3D print party on the occasion and showed it to an art bar owned by friends who lived in Milan, I did about fifty keychain designs and 3D prints in many colors, materials and sizes. I mainly used colored PLA and rubber filament supplied by Plasticink, as well as excellent wood filament by my friend Simone Fontana (from youtube tech channel FNTSMN), purchased from Filamentum. We also experimented with some generic ABS.

In addition to the kitchen, I used the printer for a number of personal projects, as I’m remodeling my home this winter break. Knowing that the 3D printer would be able to create anything I could design and download, I played with Autodesk’s Tinkercad and Shapeshifter, discovering that basic 3D design could be much more intuitive than I could have imagined. is.

Coming back to 3D printers, one immediately surprising quality of the DeltaWASP (and other Delta 3D printer manufacturers have confirmed it) is the elegance of its design. The plate basically sits directly on the floor, giving it more stability. It can be heated to 100 °C and is easily controlled with three side wheels. And the plexiglass enclosed printing space assures better temperature control.

Curiously enough, the strangest looking DeltaWASP feature was the filament pull motor that literally hangs over the extruder held in place by three green, elastic wires. It is also the one that contributes the most to the quality of production. It may be paradoxical, the more the motor is free to dance around, the less vibration is transmitted to the extruder. Another example of quality Italian craftsmanship.

The body of the machine is aluminum and polycarbonate with a glass plate. It has a relatively light weight of 20 kilograms, which means it’s not too hard to carry around. WASP’s Delta print head is very accurate and it has gotten better over the years. Even at a layer thickness of 200 microns, vertical surfaces appeared almost perfectly smooth and errors were extremely rare in everything I printed. I mainly used Cura to cut and download all the software settings from the download page on WASP’s website.

I put it to the test with Nervous Systems’ iconic bracelet, which I printed at 100 microns, and also with a few other test models, including the bland iPad amplifier, which I 3D printed in Timberfoil – I thought – Improved acoustics. In the end, I used it to 3D print a “dog” on commission for a contest on my Italian website.

I think the impressive thing about DeltaWASP is how easy it is to use. The on-board computer, with a single-color LCD display, is very similar to any other open source 3D printer and yet, the firmware is optimized and updated regularly. In fact, the latest update introduced a very useful resurrection feature.

I didn’t realize how useful it was until I turned on the dryer and oven simultaneously while the DeltaWASP was about halfway through the 2.5 hour Bold amplifier. All I had to do – after turning Lifesaver back on – was simply find the “resurrected” file on the SD card and hit start. Printing started right where I left off.

DeltaWASP is a distinctive example of Italian artisan craftsmanship applied to 3D printing. Although the attention to detail, care and passion that each member of the WASP team puts into their work is evident, the assembly process is not industrialized and not easy to scale up.
