Artist Spotlight: Ricardo Martinez

3Doodler is delighted to work with a range of artists this year to invite curiosity and spark the imagination as we design and create in 3D.

Each month, the 3Doodler team shares ideas and tutorials to help kick-start the design process. We were curious to see what our artist community would create with the same inspiration.

Last week, we explored the artistry of ice castles. 3Doodler shared a version that is easy to replicate with our free stencil and tutorial. This week, guest artist Ricardo Martinez (riikc) shared his version of an ice castle. See where he found his inspiration and how the sculpture came together.

Creating with riikc

Ricardo is a sculpture artist, painter, and photographer who explores a variety of materials and techniques in his work. Ricardo has extensive experience creating art with 3D pens and often shares his approach with the 3Doodler community.

Ricardo’s latest installation, Memento Vivere, gained worldwide attention as an interactive multi-disciplinary project using light, technology, and science to express an idea. This larger-than-life exhibit consists of a series of electroluminescent cables arranged in a skull structure that Ricardo designed with a 3D pen. The sectors of the installation light up as people interact with the display.

Ricardo lives in Brussels and travels extensively. He takes inspiration from nature, landscapes, geography, architecture, and much more. We were delighted to connect with him about his experience creating an ice castle in 3D.

3D Design Approach

Ricardo had an idea for this design and took inspiration from fantasy video games he’s played over the years, like Final Fantasy. From his home in Brussels, he looks at a large church with a castle-like appearance and eight pillars. Mixing these concepts, he began to sketch the design on paper.

“It seems like a different part of your brain kicks in and starts working as you start building,” said Ricardo. “The design evolves as you go. The castle resembles the sketch but evolved as I sculpted it in 3D.”

Ricardo used existing shapes to begin the sculpture and found it easy to keep adding material to get the form he wanted for the design. For example, he used a glass cylinder to create the pillars’ base. He could continue this process to get the length he wanted for the towers.

To design the castle, Ricardo used the 3Doodler PRO+ 3D pen and PLA, nylon, wood, and bronze filament.

“I love the smell of the wood while I’m creating. It makes me feel like I’m in a woodshop,” said Ricardo. “For this design, the wood and bronze add texture and stand in contrast to the rest of the design, which is the effect I was hoping to achieve.”

Advice for the Community

Ricardo is an experienced artist who shares his success tips freely to encourage others to pick up a pen, paintbrush, or other tool and begin creating.

“It’s important to share that you don’t need to create shapes out of thin air,” said Ricardo. “I recommend starting by using existing shapes. Then, you can find inspiration and doodle anything with objects around you.”

For new 3D pen artists, Ricardo recommends starting with a speed setting of three and gradually working up to faster settings. In this design, Ricardo found he could work effectively with a speed setting of seven or nine.

“I was impressed with the speed settings on the pen. It’s incredible how adjusting those settings can change things and make the experience much more enjoyable, given how quickly you can cover a large surface,” said Ricardo. “The PRO+ pen is much more comfortable and easier to use over long periods.”

Ricardo notes that the PRO+ makes it easier to swap materials and see what’s happening, which saves a great deal of time. He was especially pleased with how the wood detail came out on the ice castle and enjoyed adding contrast with different materials.

When working in bronze, Ricardo recommends keeping a bit of distance from the tip to the surface as the material smudges easily.

“Working in 3D evolves whatever idea you think you have, and it goes into many different directions that you can’t experience with just 2D drawing. It opens your mind to new possibilities and thinking in ways you’ve never thought before,” said Ricardo.

It’s incredible to see creators at work and watch designs come to life in 3D. Expect more artist and creator collaborations in the months ahead. Share your ideas with us. What would you like to see 3Doodler and our collaborators create? Tag 3Doodler or use #3Doodler #WhatWillYouCreate.

A Winter Wonderland: 3D Ice Castle

Ice sculptures, castles, and palaces are wonderfully artistic and inspire the imagination just as the temperatures begin to drop.

3Doodler took inspiration from the wintry weather and the long history of icy architecture to create a stunning 3D ice castle. See where we found our inspiration and design an ice castle with our latest stencil!

Ice-Inspired Architecture

Ice castles and palaces have popped up in all sorts of cold-weather locations around the world, from Montreal to Switzerland and even St. Paul.

Montreal has a long history of ice castle creations. Before modern technology, people cut ice blocks from the frozen St. Lawrence river. Montreal’s first ice palace was designed for the Winter Carnival of 1884. In addition to the ice palace, the Winter Carnival featured snowshoe races, toboggan slides, and sleigh rides.

Seeking to attract tourists and following Montreals’ lead, organizers in St. Paul, Minnesota, built an ice castle in 1885. In fact, the city has created 37 ice palaces of all different shapes and sizes to date. Today, the ice palaces appear less frequently. In fact, they are often organized to coincide with significant events, like the Super Bowl in 2018. The city of St. Paul features a video explaining how the project came together with a stunning result.

In the 1930s, mountain guides in Switzerland carved corridors and hallways with picks and saws in the center of the Jungfraujoch Ice Palace. Today, artists continue to astound visitors with eagles, bears, and penguins carved in ice. Beautiful as it may be, bundle up if you plan to visit. The temperature is a frosty -3 degrees celsius.

Designing an Ice Castle in 3D

The 3Doodler team took inspiration from traditional ice castles created with blocks of ice and more modern interpretations, like the ice palace from Disney’s Frozen. The 3Doodler ice castle stencil offers a series of easily made shapes. You can create a small or large castle by attaching the pieces together.

In the 3Doodler version, we used four large sides, two medium sides, and two small sides. Attaching these shapes together, we created alternating sides for the ice castle. If you wanted to create a larger castle, you could continue to make the side shapes to build out the castle design. Follow the process step-by-step in the ice castle tutorial.

Stay tuned for more ice-inspired designs by a guest artist. The possibilities are endless. Share your designs with us by tagging #3Doodler #WhatWillYouCreate.
