Robotic Arm 3D Printer, also known as Robot Additive Manufacturing (RAM), is a form of robotic arm manufacturing. In this innovative process, an industrial articulated robotic arm is employed to move a printhead, facilitating the additive manufacturing of components.

Unlike traditional gantry-based 3D printing methods, RAM utilizes established techniques such as Fused Deposition Modeling (FDM) or Directed Energy Deposition (DED). However, the distinct feature is that the robotic arm dynamically moves and positions the feed material throughout the printing process. Let’s not waste time, below are the guide to Robotic Arm 3D Printer.

Advantages of Robotic Arm 3D Printing:

1. No Supports Needed: Printed parts do not require additional supports, increasing design freedom and saving on material costs.

2. Overhangs and Reorientation: Some manufacturers have overcome the limitation of overhanging designs by reorienting the building platform, allowing the extrusion layer to act as support.

3. Elimination of Slicing Software: Unlike fixed-axis printers, robotic arm 3D printers use multi-axis toolpaths programmed with specialized 3D printing software, reducing the need for traditional slicing software.

4. Customization Potential: Build-your-own approach enables companies to tailor the robot arm 3d printer to their specific requirements, especially in industrial manufacturing settings.

5. Growing Availability: While there are currently few ready-made systems, the technology is becoming more common, particularly in industrial manufacturing where existing robotic arms can be upgraded with new equipment.

6. Broader Reach: Companies facing barriers in building their own systems can turn to bundled solutions offered by distributors like Evo3D, which includes training, support, and essential components for robotic arm 3D printing.

Cheaper, Sustainable Materials

The 3D printer arm uses polymer material in pellet or chip form, along with other materials like metal, clay, and concrete. Using pellets allows for cheaper, sustainable options, including the use of recycled plastic. This method also enables faster printing compared to conventional filament-based 3D printers.

Robotic Arms for Metal & Concrete

Robotic arm 3D printers, also known as 3D printing robot, are versatile, handling materials like metal and concrete. They find applications in construction and architecture, with companies like Vertico and Twente AM offering custom configurations for various projects.

Manufacturers Of Robot 3d Printer

The market for robot-assisted 3D printing is niche, resulting in limited printer manufacturers. Currently, it involves mix-and-match options, where robotic arms and extruder end-of-arm tools may be purchased separately. Many companies offer customizable packages, known as cells, to cater to specific printing requirements. As a result, more companies offer robotic arm 3D printing as a service using their own proprietary printers. However, this trend is expected to change as the benefits of robotic arm additive manufacturing become more apparent.
