How to commission a bespoke piece from a designer (and what it costs)
At Blacksand you commission a piece in five steps: share your idea, meet up to three designers from the collective, design it together, approve the final render, then it is produced and delivered. The price is a design fee, quoted upfront, plus the piece by weight at €158 per kilogram. There is no minimum: one piece or a full series.

Commissioning a piece used to mean finding a designer, then finding someone who could make it, then hoping the two agreed. At Blacksand both sit in one place: a collective of designers working in one material, and the production that turns their drawings into finished pieces in black quartz sand.
The five steps
- Share your idea. A sketch, a reference image or a full brief. Brands often arrive with a brief, private clients with a feeling.
- Meet your designer. Pick up to three designers from the collective, or we build the team for you.
- Design it together. The designer develops a 3D model with you, with revisions. The design fee is quoted upfront.
- Approve the design. A final render, size and finish. Nothing is produced until you say yes.
- Produced and delivered. The piece goes into production, then it is assembled and shipped from Valencia.
What it costs
Price = design fee + the piece by weight.
- Design fee: quoted with your brief, before any design work starts.
- The piece: its weight in kilograms × €158, including VAT, plus any second material such as glass, metal or a light kit, each at its own price.
- Trade clients (architects, interior designers, studios) have their own reduced rate per kilogram.
Because price follows weight, a hollow form or an open lattice costs less than a solid block of the same size. Detail adds nothing. See How much does sand 3D printing cost? for real examples.

Who commissions
- Brands and companies: signature pieces, product lines and limited series, developed with one designer or a team from the collective.
- Architects, interiors and hospitality: lighting, furniture and wall pieces for a specific project, from one room to a whole hotel. A typical brief: a lobby light about 1.2 m tall, twelve of them.
- Private clients: a piece you can picture but not draw. You bring the idea, we bring the designer.
Already have a design?
Skip the matching. Send the drawing or 3D file (STEP, OBJ, STL or 3DM) through Production: we check it for sand printing, flag anything that needs a tweak and come back with size, finish and a price by weight. Read Designing for sand 3D printing first.
