Delta WASP: 3D Printed Furniture With Beauty & Form

Delta WASP 3D Printing Case Study: How a Guatemalan architect creates stunningly intricate furniture designs achievable only with a large format 3D printer.

A sculpture machine – this is how an artist sees a 3D printer. To furniture designer, architect, and artist Alejandro Estrada, his 3D printer is a tool on par with a hammer and chisel. He didn’t choose this method because it was faster, cheaper, or easier. He creates with a 3D printer because it expands what’s possible in design and challenges his imagination.

“When you know how to draw a line it’s completely unimportant if it’s with a stick, with your hand, with a pencil, or with a computer,” he says. “And when you know how to draw a line and you find much more accurate ways of doing so, then you take this new way of doing to create a work of art.”

Estrada’s art includes contemporary furniture design through additive manufacturing, specifically with the technology of Italian printer manufacturer WASP.

Art Meets Technology in Unique and Beautiful Ways

Estrada’s 3D printed furniture isn’t just an expression of art, it’s an expression of additive manufacturing technology itself because he only produces pieces that can’t be made any other way. “If it looks like you can do it with your hands or it can be done with another machine, then I think it doesn’t make any sense to 3D print it,” he says.

Some designers might imagine a chair then look for a unique way to produce it. Instead, Estrada begins with the method – the 3D printer – and then, with an intimate understanding of its capabilities, imagines what type of chair only it could produce.

And with this approach the Truss line of outdoor furniture was born. Retailing in exclusive designer furniture galleries in New York, Miami, and Los Angeles, each piece of Estrada’s furniture created by his company, Piegatto, is a solid, intricate object of art that is as beautiful as it is comfortable. Printed from biodegradable and weatherproof PLA with openings that create transparency, the chair stretches in some parts and stays sturdy in others.

Not many 3D printers are capable of producing prints at this level of complexity and size, and finding the right printer took Estrada time and testing.

Choosing the Right Printer and Material

Dozens of printer manufacturers display their machines at the IDTechEx Show in California every year. Estrada spoke with several and narrowed the companies to one that appeared to have the quality and scale he needed to create unique outdoor furniture. He traveled to Germany, conducted printing tests, and was very close to buying a machine, he says. “But the big problem was that we could only buy the material through them and, for the material alone, one chair was around $700. For what we wanted to do, it didn’t make any sense.”

The material had to be less expensive. Spools of filament, which start at $20 per kilogram, were out of the question for making a full-size chair. Instead, Estrada looked at thermoplastic materials in pellet form, which can run as low as $2.50 per kilogram.

More commonly used in injection molding, pellets are not only less expensive but come in a wider range of materials than filament, including a long list of recycled and sustainable products. Plus, because a high volume of pellet material is fed via a hopper into the extruder, pellet-based 3D printers typically can print large objects quicker than filament-based printers.

Sustainability is an important aspect of Piegatto’s designs. Not only should the furniture be made of sustainable materials but the process should create little waste, which is a hallmark of additive manufacturing.

For Estrada, 3D printing is a way to add even more beauty to an object. “We realized that we needed to do wise objects without waste, as the beauty of an object not only resides in what you see as a final product, but what … you practice in achieving that beauty.”

An Innovative Artist Meets an Innovative Printer

Material, size, and quality needs led Estrada to Italian printer manufacturer WASP (World’s Advanced Savings Project).

Known for its mission to 3D print clay houses to solve the world’s housing issues, WASP has grown over the years to offer a wide range of industrial printers for construction, architecture and design, art and culture, energy, medical devices, and food.

Test prints on the Delta WASP 3MT INDUSTRIAL 4.0 printer convinced Estrada to make the investment. Although WASP offers a printing service, purchasing the printer at $40,000 with accessories, made more sense, he says, not only because his design company is located in Guatemala City, Guatemala, some 10,000 miles away from WASP, but because his creative process required multiple iterations and testing

“Imagine all the trials and errors that we make,” says Estrada, “it would be impossible to do it with an outsource service.”

Piegatto’s two WASP printers (he also owns the Delta WASP 40100 Clay) run almost every day when there aren’t electricity blackouts, which are common in Guatemala. It takes six days to print one Truss chair and customer demand is high.

“We’re working on some modular benches for a shopping center, as well as some small pieces and vases,” says Estrada. “And the other thing is testing and more testing.”

Bikechair

3D printed postural sitting

The Eni Versalis project, in collaboration with WASP, highlights the possibilities that the large scale-3D printing offers.
For this project, materials optimized for pellet printing, thermoplastic material in grains supplied by Eni Versalis have been printed with the Delta WASP 3MT INDUSTRIAL.
A joint experimentation that gave birth to Bikechair, a postural sitting for passive gymnastics signed “Gurioli Design“, printed in ABS. The installation combines it to a table 3D printed in HDPE .
The use of these performing materials and the dedicated design confirm that 3D printing is  the digital manufacturing heart, as it’s able to  transform  a design project into a finished product in scale 1:1
During PLAST fair 2018 in Milan, the Bikechairs were presented in Eni stand.

3DiTALY and WASP reward the young design-talents

The  contest “Una seduta per 3DiTALY” , promoted by 3DiTALY Pescara in collaboration with WASP,  ended with the victory of  Vincenzo Fantini -  The joined projects were more than one hundred, seven were the  finalists who attended  the 3D printing- intensive laboratory  performed with  Delta WASP 3MT.

“Mould” is the name of a resistant, elegant, flexible and ergonomic chair, realised just in one single  PLA block by Vincenzo Fantini, young winner of the contest “A seat for 3DiTALY". Thanks to his creation, Vincenzo has won a 3D Delta WASP 2040 printer, with whom he will be able to shape his future projects.

A call for a new design concept

Aim of the contest for dreamers and designers, was the projecting of a seat to be entirely 3D printed – or realized with 3d printed parts to be assembled the one with the other or with other material parts,  to form a chair;   an easily printable shape chair but above all  functional, intelligent, usable:   the purpose, shared by WASP,  is to promote new technology-use in the standard projecting process to obtain, independently, original objects which can be integrated in every day life.

It's a big change: thanks to 3Dprinting, you can create by your own – your personal furniture, you can think and bring forth to new, more effective and sustainable living solutions.

One hundred projects and seven finalists for a 3d printing full-immersion

The proposal has triggered a big interest: more than 100 projects of any kind and shape, have arrived, many strange but clever, accurated and practical, from a chair for children that if upsidedown can become a rocking, to  the mono-block chair for outdoors that solves the water stagnation in case of rain. The seven selected finals have attended a two days full-immersion performing with our Delta WASP 3MT:  on 11th and 12th November the designers have been driven to the modelling and finalisation of the project for the chair 3D printing in real size; a unique opportunity which allowed the participants to experience the innovative technology of the pellet extruder developed by WASP.


Delta WASP 3MT : contest protagonist

The meeting has engaged and excited the audience, with its live 3D printing performed with a big size Delta WASP (3m. high), a surprising  multi tools machine, speed and versatile, able to bring forth to furniture, furniture parts or any other kind of objects under everybody's eyes . With this stimulating contest opportunity, WASP has contributed to promote self-production culture  in the furniture components field – moving a little more onward  the borders of 3Dprinting world.

As further confirmation, during the 13th November award-ceremony, occured during the new 3DiTALY headquarter inauguration in Pescara, one of the biggest decorating element ever printed in Italy,  has been realised.
