PUR2526028 Rev. 06/12/2025

The Louisiana Tech University Oﬃce of Purchasing is now accepting Sealed Bid solicitations for the Purchase of a Concrete

3D Printer and Auger for the College of Engineering and Science. This solicitation seeks bids for the purchase of a 3DPotter

SCARA V4 3D Printer with an Auger HP24 Extruder or equivalent.

The requested 3D concrete printing system is a robotic arm-based, rotary 3D printer designed for printing cementitious

materials, including concrete, highly viscous and packed concrete such as ultra-high-performance concrete, ﬁber-

reinforced mortars, and clay-based mixtures. The system shall be capable of printing full-scale elements such as beams,

walls, and architectural or structural components. The requested printer and auger shall meet the following minimum

speciﬁcations:

Power and Electrical Requirements:

• 110-220 VAC, 50/60 Hz, 4A.

• Standard single-phase operation suitable for laboratory use.

Control and Software:

• Full control through web interface. Machine control shall require no software installation.

• Real-time printing monitoring and control: The system shall provide real-time monitoring of print progress, layer

timing, and estimated time remaining, and shall allow real-time adjustment of extrusion and movement

parameters through the control interface.

• Compatible with standard CAD modeling software (e.g., Fusion 360, SolidWorks).

• Compatible with standard slicing software such as Simplify3D or Cura.

• Connectivity: The printer should be fully controllable via Wi-Fi or local network connection. The printer shall be

Wi-Fi enabled, capable of broadcasting its own network or connecting to an existing local network.

Printing Capability

• 360-degree robotic arm with a unique circular print envelope.

• Capable of printing multiple objects sequentially within the envelope

• Adjustable printing speed: 30–100 mm/s (1.2–3.9 in/s).

• Printing with clay and a wide range of cementitious materials

• Ability to print high-viscosity, high-packing-density cementitious materials such as ultra high performance

concrete, as well as ﬁber-reinforced concrete.

• Compatible with aggregates < 3-4 mm

• Direct-extrusion system, no air compressor required.

• Suitable for printing walls/beams approximately 1 ft deep and up to ~5 ft long, and any conﬁgurations ﬁtting

within printing envelope

Mechanical Design and Construction

• Heavy-duty industrial construction, primarily CNC-machined cast aluminum components.

• Printer weight: approximately 85 lb (transportable by two people).

• Mounting: ﬂoor or tabletop mounting using bolts/anchors for stability.

• Hybrid closed-loop stepper motors with computers with telemetry for position correction.

• Harmonic drive units for high-precision motion (fraction-of-degree accuracy).

• Low-noise operation suitable for indoor laboratory environments.

Required space

PUR2526028 Rev. 06/12/2025

• The printer requires approximately 6-12 in of clearance beyond the nominal print area. The required space will

vary based on the size of the model being printed. The printer will be installed in a dedicated space sized for

partial or full use of the print envelope. Print area is shown in gray in Figure 1.

Figure 1.Print area

Auger/ Extrusion System

• The printer shall be compatible with various pumps/extruders.

• The requested auger (Auger HP) is constructed of aluminum/composite material compatible with cementitious

mixtures not reactive with aluminum or ABS plastic.

• Auger volume (Auger HP): 3.5–4 L; must allow continuous reﬁll without print interruption.

• Auger size and weight: ~14 in diameter, ~28 in height, weight ≈ 12 lb (5.4 kg), Attachment sleeve outside

diameter ≈ 3.5–4 in, height ≈ 5 in.

• Includes three interchangeable nozzles: 1 in, ¾ in, and ⅝ in diameters.

• Auger may be manually fed or connected directly to a pump.

• Designed for quick disassembly and cleaning suitable for lab use.

Accessories and Deliverables

• All tools required for assembly and maintenance shall be included.

• Printed and video (or online) assembly instructions shall be provided.

• One-year minimum warranty against manufacturing defects.

• Shipping to the destination shall be included in vendor’s quote.

• Transportation and installation must require no special utilities or site modiﬁcations beyond standard supply.
