Regolith composition, material properties, and power restrictions pushed the 3DP’s design to maintain the initial processing Standard Operating Temperature (SOT) just above 1,600 °C to melt both SiO2 and FeO in preparation for printing and more intensive material processing and refining. The silicate, being good in compression, will be fused together and work as a “concrete substitute” using leftover materials as it’s agregate. The iron, being good in tension,

will be used as a “rebar substitute” and form strong tension straps.

The 3D Printer/Processor (3DP) is the exterior workhorse of the Ansile-Hab. It is the delivery point for all collected resources. It is designed to have a modular evolvable chassis which will accommodate material storage and processor augmentations.

After landing it is connected to the power plant and moved into position by the Multi-Purpose Shoe Bots (MPSBs). Once positioned, the 3DP will lock its primary struts and release the MPSBs. The size of the boom provides access across a large work area. This insures that one habitat can be printed to completion without having to adjust the 3DP’s position nor

stop the material collection or printing processes.

Once the Pressure Vessel and Protective Mound have been printed to completion, the MPSBs will reconnect to the 3DP and relocate it to the site of its next print. From there, the print process will repeat and a colony will form. As the mission continues, new technologies and devices will be attached to the 3DP allowing it to print objects in better detail with a larger variety of materials.

Ancile-Hab Floor Plans

Level 3 (left) is a 46.86 m^2 mix of public and private spaces. Crew quarters, the galley, wardroom, gathering area, exercise, recreational, and auxiliary command are all located here. The floor offers a combination of open and enclosed areas that can be modified according to the crew preferences and necessity. Some elements can fold or lift out of the way, such as the table and beds, providing alternate paths or spaces.

Level 2 (right) is 27.69 m^2 and the primary work space and is outfitted for all lab missions. There are multiple lab

spaces to provide for the needs of the multiple missions at the same time.

Storage and flexible work areas fill the spaces between labs. The internal 3D

printer arm will primarily reside here after it has printed the interior of the habitat.

Here it can change its head to participate in science, maintenance, or repairs.

Level 1 (left) is the PUC, a 25.45 m^2 service floor where pre-integrated ECLSS, hygiene, and other essential functions are located. It has an airlock (with two EVA suits) and two suitlocks (two additional EVA suits) for egress operations of the four crew members. There are two hatches that can accommodate connecting inflatable tunnels to other Habs and facilities for future expansion.

Ancile-Hab Section Perspective

Design Advantages• Flexibility in design is critical and all elements are created to enable printing of a multitude of shapes and sizes. • “Ancile” architecture ensures protection and capabilities for adjustment of the equipment to correspond with mission evolution• The MPSBs work simultaneously with construction operations by constantly sweep-mining regolith dunes continuous printing. • The process of sweep-mining regolith does not require complex digging machinery or advanced low-gravity mining equipment. • The 3DP’s modular and evolvable framework allows augmentation to keep up with mission demands and ensure economical expansion.• The PUC modules are “turn-key” habitats with ready-to-run systems integration and zero assembly required after their initial fabrication.
