The Art of 3D Printing: Crafting the Fortune Chair by Heller Furniture

The Fortune Chair by Heller Furniture is priced at $1,175, prompting the speaker to consider the feasibility of 3D printing it instead.

The speaker reflects on their previous experience with 3D printing designer furniture, specifically mentioning the Magic Spun Chair, which, despite its imperfections, demonstrated the potential of 3D printing.

To create a 3D model of the Fortune Chair, the speaker had to start from scratch due to the lack of available designs. They utilized drawings and measurements taken from a high-end furniture store to aid in the modeling process.

The speaker describes the Fortune Chair's design as resembling an elongated fortune cookie, which they found simpler to model than initially anticipated. They encountered difficulties with their usual 3D modeling software, leading them to explore iPad apps for organic sculpting.

The speaker learned to use Nomad Sculpt, an iPad app costing $20, which they found intuitive for 3D sculpting after following YouTube tutorials for a few hours.

After struggling with their initial approach, the speaker switched to manipulating a sphere, akin to working with clay, and restarted the modeling process seven times over the course of a week to achieve a satisfactory design.

Once the model was created, the speaker used Fusion 3D software to refine the seat profile, making subtle adjustments until it resembled a comfortable Fortune Chair, ultimately confirming its similarity to the original design through reference photos.

The speaker noted that while their previous project required splitting the Magic Spun Chair into 63 pieces for printing, the Fortune Chair only needed to be divided into 21 larger sections, thanks to the capabilities of the Sovel SV08 3D printer.

The Sovel SV08 3D printer, which boasts a large build volume and fast printing capabilities, was instrumental in the project. The first print took nine and a half hours, but the speaker discovered that including voids in the model actually increased filament usage.

Due to the SV08's loud operation, the speaker moved it to their balcony for printing until they could relocate to a new studio. They acknowledged the risks of outdoor printing, particularly in cold weather, but utilized an enclosure provided by Sovel to maintain a suitable environment.

The speaker's outdoor printing was cut short by the onset of the rainy season, but they were relieved to finally gain access to their new studio, which would provide a more controlled environment for their 3D printing projects.

The speaker dedicated a month to full-time 3D printing, utilizing the Silvel SVO-8 printer, which features Wi-Fi connectivity and automatic bed leveling. The printer is highlighted as fast, capable, affordable, and open-source, with a recommendation to check it out via a provided link. Additionally, the speaker mentions using color-changing PLA from Silvel.

Initially, the chair was designed with 21 printable pieces, but the speaker admits to splitting some awkwardly-shaped pieces to avoid support material and to expedite the printing process. Some pieces were printed in parallel on smaller printers. Alignment holes were modeled into the pieces, which were assembled using 3D-printed dowels for alignment, while the actual strength came from a 3D glue that melts PLA, creating a strong bond.

The assembly of the chair required 17 spools of filament, resulting in a total material cost of $306. The speaker expresses skepticism about whether all pieces are accounted for during assembly.

The speaker refrains from sharing the 3D printing files for the chair online, citing concerns about potential intellectual property violations with Heller Furniture. They emphasize that the project is a fun experiment rather than a commercial threat, hoping it will promote interest in the original chair rather than undermine it.

While sanding the chair, the speaker acknowledges the environmental impact of microplastics and uses a new dust extractor to minimize airborne dust. They wear a respirator for safety and explain the dual process of sanding down high spots and filling low spots to achieve a uniform appearance. The body filler used is similar to that employed in automotive repairs, and the speaker admits to initially poor technique but anticipates improvement.

The speaker reflects on the design flaw of a curved front edge that could lead to tipping, indicating a need for adjustments before proceeding with the priming and final finishing of the chair.

The speaker discusses the modification of a chair, noting the addition of 3D-printed feet designed to counteract stability issues. After six weeks of work, the first coat of filler primer is applied, marking a significant moment in the project. The speaker expresses excitement about seeing the chair as a single, homogenous object, despite knowing that further filling and sanding will be necessary.

The speaker uses filler primer, a thick spray paint intended to fill surface inconsistencies, applying a total of seven cans throughout the project, which brings the material cost to $358. Initially, the primed chair appears smooth, but upon closer inspection with angled light, surface blemishes become visible, revealing areas needing further attention. This technique is likened to methods used by square board makers.

After two coats of primer, the speaker finds the surface satisfactory but not uniform enough, leading to a third round of body filler application. Approximately one pound of bondo is used, increasing the material costs to $373. The speaker also notes the use of two 4-ounce containers of 3D gloop, raising the total material costs to $443. Despite initial dread about the filling and sanding process, the speaker finds it satisfying, and after the third coat of primer, the chair is nearly perfect.

The speaker applies a color coat, specifically Rustic Orange, which initially appears brighter than expected. Despite initial doubts about the color choice, the speaker finds that as additional coats are applied, the color begins to fit the chair's post-modern aesthetic. The speaker eagerly anticipates the reaction of their wife, Eden, who has not seen the chair since its initial printing.

Eden's reaction to the finished chair is overwhelmingly positive, expressing excitement and affection for its handcrafted appearance. Her enthusiastic response includes multiple affirmations of love for the chair, highlighting the success of the project and the satisfaction it brings to both the speaker and Eden.

The speaker concludes the discussion by thanking top supporters on Patreon and YouTube memberships, specifically mentioning Paige Arlts, Luis Armendariz, and their mother, Kathy Curt, expressing love and appreciation for their support.
