Material
Everything you need to know about 3D printing mortar.
What is the cost of 3D printing materials?
Depends on performance and additives. Standard mixes are cheaper than fibered or ultra-high-performance ones. Additives (accelerators, superplasticizers) vary in cost share.
What material is used to print a 3D house?
Mainly specially formulated mortars: pumpable, extrudable, quick-setting. Fibered or not. Adaptable to local resources via custom formulations. Our Termix-3D 'Albert' material is produced in our plant in northern France.
What materials are compatible with 3D printing?
Printers accept many materials: special mortars, micro-concretes, fibered concretes, local formulations. Both MaxiPrinter and MiniPrinter handle aggregates up to 10 mm.
What is the carbon footprint of a 3D-printed house?
Varies by formulation. Traditional concretes are clinker-rich, while our mixes use low-carbon binders. An Environmental and Health Declaration Sheet (FDES) must still be made for precise evaluation.
What is the setting time of 3D printing concrete?
Fresh structuring occurs within minutes for layer stacking. Initial set: ~1 hour. Strength gain continues for 28 days. Times vary with composition, humidity, temperature.
What is the impact of humidity and temperature?
Low humidity can cause fast surface drying and cracks. High heat may accelerate setting or cause cracking. We recommend following supplier guidelines. For Termix-3D 'Albert', use in 5–25°C and 50–90% RH.
What is the durability of 3D-printed concrete?
Like traditional concretes, it lasts decades. Durability depends on formulation (fibers, additives, binders) and proper application.
What materials has Constructions-3D developed?
We develop specific printable mortars adapted to local conditions and project needs, combining pumpability, fast setting, strength, and durability.
Can local materials be used to print a house?
Yes. We help clients formulate mixes with local sand, cement, aggregates. This reduces costs, carbon footprint, and simplifies supply.
What services does Constructions-3D provide for material support?
We provide full assistance: formulation help, compatibility tests, and on-site technical follow-up to ensure materials meet performance and local constraints.
