Advertised equipment pricing starts at $400,000; size, configuration and accessories change the quote. This is not a home construction price.
Owens Crossroads reports lower costs than conventional construction, without a dollar budget or quantified saving on that page.
Availability & limits
Titan can be ordered; advertised deliveries begin in 2027. Existing completed projects do not establish Titan delivery today. Regional availability varies.
Advertises approximately five months from confirmed order to independent operation. Construction enquiries are referred to customers or regional partners.
Public partnership offering; project acceptance, local crew capacity and scope require confirmation.
Project evidence
ICON reports Wolf Ranch’s 100 residences finished in 2025.
Customer portfolio covers housing, commercial buildings and infrastructure.
Published Walmart wall-printing records include Owens Crossroads and Athens.
PERI’s offering uses COBOD equipment. These represent overlapping supply relationships, not seven independent printing technologies. Regional support, quoted scope and project approval need their own confirmation.
02 / INSPECT THE PROJECT RECORD
The figures behind the footage.
Read what the project teams actually disclose. Printing time, onsite operations and total build periods have different scopes; community scale is a different kind of evidence.

Printing operation documented
FMGI records 11 days onsite for the printing operation. This is not the total calendar duration of the addition or the wider store renovation. A complete-project elapsed duration is not disclosed in the reviewed sources.
Printed scope: Walls for a 5,000-square-foot expansion. Seven is the source’s print-day count, not the complete building delivery period.
Project status: Company reports completion in February 2025.
Cost disclosure: Savings claimed; no dollar budget or quantified saving disclosed.
Reported project area: 5,000 sq ft. Area is not a priced scope.
FMGI reports 12 weeks for the total build and 45 printing days. Alquist reports 48 print days. The reviewed sources do not reconcile that difference. Twelve weeks is retained in its reported unit; no exact calendar-day duration is inferred.
Printed scope: Wall printing for an 8,000-square-foot addition. The print-day counts are not the complete building duration; FMGI separately reports a total-build period.
Project status: Company reports completion in fall 2024; its account describes weather and equipment difficulties.
Cost disclosure: No dollar project budget or matched conventional cost disclosed on this case page.
Reported project area: 8,000 sq ft. Area is not a priced scope.
ICON documents the community scale, plan count and finish year. Its project page does not provide a comparable total of print hours, print days or whole-community elapsed days. These project facts replace empty timing tiles; they are not productivity measures.
Printed scope: 100 residences; source identifies Vulcan Block 3–4. Floor plans vary, so no single community area or comparable print duration is assigned.
Project status: ICON’s project page lists the community as finished in 2025.
Cost disclosure: No construction budget disclosed on the project page. Titan equipment pricing is not this project’s cost.
Project-team reports have not been independently audited by StackX. An unavailable figure is explained where it matters; it is never filled with a guessed value. Printing days, onsite days, reported build weeks and community counts must not be ranked as equivalent productivity measures.
03 / BUILD THE MISSING COST BRIDGE
Get a quote you can actually compare.
01
Define the same home
Use the same location, floor area, plans, performance requirements and finish level. Record which drawings and engineering each price follows.
02
Resolve the wall package
Identify printed material, reinforcement, lintels, insulation, testing, penetrations, finishes and connection details. Assign a cost owner to every inclusion and exclusion.
03
Price the printing operation
Record transport, setup, site access, power, water, mixing, crew, consumables, equipment support and weather allowances. Separate one-time project charges from per-home costs.
04
Close the remaining build scope
Include land and site work where relevant, foundations, roof, windows, doors, electrical, plumbing, HVAC, interior work, permits and inspections. Avoid counting an included component twice.
05
Use the full calendar
Keep machine hours, site working days, elapsed construction duration and occupancy milestones distinct. Price holding costs across the duration you actually enter.
06
Verify delivery in this location
Request project-specific engineering, approval status, material availability, crew availability, service support and warranty terms. A completed project elsewhere does not settle these questions.
Enter your own material, labor and remaining-home costs. See the capital tied to ownership, the output assumptions behind its allocation and the difference that elapsed time makes.
This is a curated edition reviewed 2026-09-07. Company selection is not comprehensive. Source pages can change; availability, pricing and system versions require reconfirmation with the provider. Announced equipment and delivery dates are distinct from the technology used on completed projects.
Companies are compared through their own public descriptions and project reports. A claimed saving is not treated as an audited result. No commercial relationship, certification, procurement recommendation or local permit determination is implied. Different materials, wall details and support models cannot be made equivalent by converting the unit price alone.
The calculator uses visitor-entered assumptions and does not import these prices into a finished-home estimate. This edition does not automatically refresh supplier offers. Corrections and new comparable evidence can inform a later reviewed edition.
