Modular FFF-3D Printer

Introduction

Firstly, allow me to share a bit about myself and the motivation behind this project.

From a young age, I have been exceptionally inventive, a trait that has accompanied me into adulthood.

I derive immense satisfaction from conceptualizing new constructions and bringing them to life, be they mechanical or electronic.

The field of mechatronics captivates me the most, offering a broad spectrum of opportunities to learn and discover, including mechanics, electronics, informatics, pneumatics, and hydraulics.

My aim is to inspire others to explore new frontiers and engage in diverse areas.

This project is part of a required project assignment, and I selected the modular FFF 3D printer for practical reasons—I wanted a machine that occupies minimal space yet offers a multitude of possibilities.

Project Overview

Within the framework of my project, I am developing and constructing a Modular FFF, also known as an FDM 3D printer.

Modularity, in this context, implies that its functionality extends beyond 3D printing. The machine can also function as a laser engraver, light duty CNC machine, EDM (Electrical Discharge Machining), and much more. Your imagination knows no bounds. Implementations for producing PCBs (Printed Circuit Boards) are also possible, eliminating limitations for any maker.

Through the later release of source codes and CAD files, anyone can bring this machine to life, contribute to its improvement, or add additional functionalities.

The switch between functions is facilitated by the use of quick-change systems using eccentric clamps. Both the tool for the desired operation and the platform can be easily swapped.

Modularity also denotes the easy assembly of various components, each with a defined place.

Many parts are produced using a 3D printer, reducing costs, and allowing for quick and straightforward replacement of damaged parts.

Project Specifications

The build volume is 350 x 350 x 350 mm—a compromise between sufficient space for larger objects and minimizing the machine's size.

For 3D printing, an E3D Revo Hemera XS Extruder is used. To reduce heating times and ensure even heating, an casted aluminum plate and a 500W silicone heating bed are used.

Some other applications are:

For CNC machining, a 200W spindle is employed for smaller tasks, with an MDF plate serving as the base.

A 10W laser is used for cutting and engraving materials, supported by an aluminum profile substrate.

The linear modules are designed to house all axis components within a casing, protected by a metal band against dust and dirt, reducing maintenance time and costs.

The modules are connected via CAN-Bus to have less wires. The pcb for the linear modules is currently under development.
