At 3DPI, our mission is to deliver high-quality journalism, technical insight, and industry intelligence to professionals across the additive manufacturing (AM) ecosystem. Whether you’re designing aerospace parts, building dental workflows, investing in next-generation materials, or shaping national AM strategy, you’re part of the reason we do this. But we want to go further. And that means hearing from you. 📋 Take the 3DPI Reader Survey We’re launching a short, focused reader survey to help us understand: What you value most in our content What’s missing How we can better serve your professional goals This is your chance to tell us: What kinds of stories or tools would help you do your job better Whether you want more technical explainers, market trend analysis, procurement tools, or vendor insights How 3DPI can improve your daily workflow—whether you’re in R&D, strategy, production, investment, or academia It takes less than 5 minutes. Your input directly informs editorial priorities and platform features. Why It Matters There’s a lot of noise in the AM space: press release churn, hype, and recycled headlines. At 3DPI, we aim to cut through that and bring you reporting, insight, and tools that actually move the needle. But to do that well, we need clarity on what you actually use, trust, and want more of. This survey helps us align what we publish with what you actually need; whether that’s: In-depth coverage of standards and regulations Real-world case studies that go beyond the brochure Technical deep dives Trend briefings or expert interviews Your voice shapes that roadmap. Thanks in advance for sharing your time and insight. We’re committed to keeping 3DPI the trusted source for professionals building the future of manufacturing.

Casa De Blas | © Hisao Suzuki Set on a hillside in Sevilla la Nueva, a town southwest of Madrid, Casa De Blas is a distilled expression of the architectural dialectic between weight and lightness, earth and sky. Designed in 2000 by Spanish architect Alberto Campo Baeza, the house is both an act of landscape intervention and a metaphysical construct, a spatial meditation on essential form and material logic. Casa De Blas Technical Information Architects1-3: Alberto Campo Baeza Location: Sevilla la Nueva, Madrid, Spain Area: 250 m2 | 2,690 Sq. Ft. Project Year: 2000 Photographs: © Hisao Suzuki This house aims to be a literal translation of the idea of the tectonic box upon the stereotomic box. Like a distillation of the most essential in architecture. Once again, more with less. – Alberto Campo Baeza Casa De Blas Photographs © Hisao Suzuki © Hisao Suzuki © Hisao Suzuki © Hisao Suzuki © Hisao Suzuki © Hisao Suzuki The Architecture of Duality: Ground and Sky Campo Baeza’s work consistently revolves around a search for architectural clarity. In Casa De Blas, this clarity manifests as two boxes: a grounded concrete volume that holds the domestic program and a glass pavilion above that elevates the act of looking. The house is not merely built on the landscape; it is in dialogue with it. The conceptual strategy of Casa De Blas is rooted in a tectonic-syntactic opposition between the stereotomic base and the tectonic roof. The lower portion consists of a robust concrete platform embedded in the earth like a carved podium. This base supports a lighter glass structure above, where steel elements define the enclosure with minimal mass. The house engages the site with careful restraint. Rather than dominate the hilltop, it accepts the slope and turns its attention to the northern view of the Sierra de Guadarrama. This orientation informs light and shadow’s spatial organization and phenomenological qualities. Inside the concrete base, the architecture follows a precise logic. A service band is located toward the rear, while primary living spaces occupy the front, facing the landscape. Square window openings, deeply set into the thick walls, frame views with the intentionality of a camera obscura. These apertures do not merely let in light; they shape perception, creating a sense of distance and inwardness. The Pavilion as Apparatus for Contemplation Above this grounded core, the transparent upper volume serves as a lookout. Reached from the interior by ascending stairs, the glass box sits lightly on the podium, offering a counterpoint to the cave-like enclosure below. There is no visible carpentry, just frameless glazing and a white steel canopy, which shades the upper level while preserving its airy, open quality. The north-facing glass stretches toward the edge, embracing the panoramic view. On the southern side, the volume recedes to create a shaded void, regulating solar gain. This sectional asymmetry allows the architecture to perform environmentally without compromising its compositional purity. Campo Baeza describes the house as a literal translation of the idea of a tectonic box upon a stereotomic box. The reference is not metaphorical but structural and spatial. The upper pavilion is not a symbol of transparency but a mechanism for perception. In this way, the house operates as a philosophical instrument as much as a dwelling. Casa De Blas Proportion and Compositional Rigour The power of the project lies in the spatial sequence from the heavy to the light, from the shaded to the luminous. The contrast between these two atmospheres creates a duality of experience: shelter and openness, introspection and projection. The structural order contributes to this sense of serenity. Steel supports are arranged in double symmetry, reinforcing the composition’s static quality. Nothing feels arbitrary. Every gesture is reduced to its essential nature. The palette is limited to concrete, glass, and steel, yet the result is rich in meaning. The interior is equally restrained, avoiding superfluous detailing. It is architecture as a frame, a backdrop for landscape and thought. Campo Baeza’s work here touches the territory of the poetic, not through expressionism but through control and abstraction.

Renowned for his minimalist and essentialist approach, he emphasizes the interplay of light, gravity, and proportion in his designs. His notable works include the Casa Turégano, Casa de Blas, and the Caja de Granada headquarters. Campo Baeza was a full-time design professor at the Escuela Técnica Superior de Arquitectura de Madrid (ETSAM) from 1986 until his retirement in 2017. He has received numerous accolades throughout his career, such as the RIBA International Fellowship and the Heinrich Tessenow Gold Medal, recognizing his contributions to contemporary architecture.
