Designing a 3d printer that can create a coral reef type structure

Research and Information

Summary

Building a machine capable of creating a coral reef structure involves using large-scale concrete printers as a starting point. The material primarily used is calcium carbonate. Various methods and designs are being explored, including jetted water and clay printing head assemblies.

Key Points

- Material: Calcium carbonate
- Printing method: Jetted water, clay printing head assembly

Building the 3D Printer

Overview

The project involves designing and building a 3D printer capable of creating coral reef structures. The printer uses a clay printing head assembly where a screw presses the material out of a tube, similar to a French press.

Parts

- PVC pipe for casing
- 3D printed screw
- Motor
- Duet3 and power supply
- Various attachments and hardware

Steps

1. Assemble the frame.
2. Print the screw and attach a motor.
3. Test the mud pump with the current setup.
4. Scale the parts larger using Cura program.
5. Install Duet3 and power supply.

Notes

- The objective is to use hardware store available PVC pipe as the casing to reduce printing time and allow for more options.
- Several builds were attempted, and not all reached operational status.
- The journey involves turning an idea into a finished product.

Problem

Attaching the motor and moving the media is challenging.

Solution

Test the current setup and scale the parts larger using the Cura program. Use PVC pipe for the casing to simplify the build and allow for more flexibility.
