Welcome to the Fab@Home Catalog

Here you can select which model of Fab@Home unit you would like to build.

Model 2

Model II

The Fab@Home Model 2 was designed from the ground up for ease of construction and maintenance, simplicity, cost reduction, and better print performance compared to the Model 1.

The public release of the Model 2 is currently underway. CAD files and basic assembly instructions are available, see more information here:

Fab@Home: Model 2 Overview

Model 1

The Model 1 is the original Fab@Home fabber.
It consists of:

Model 1 Chassis
Model 1 1-Syringe Tool
Model 1 4-Axis Electronics
Model 1 Firmware
Model 1 Application
Model 1 USB Drivers
Model 1 Style options

The Model 1 is the first Fab@Home system. It includes everything necessary for basic, multimaterial desktop fabrication. It makes use of a basic "syringe pump" material dispensing tool, with disposable syringes to enable dispensing of a wide variety of materials. It uses "linear stepper motors" - stepper motors with lead screws attached - as the actuators, and has 4 axes of control - 1 for the syringe tool plunger, 1 for the Z axis (the vertical motion of the table on which parts are built), and 1 each for the X and Y axes to move the syringe tool along the paths required to build up a part layer by layer. The Model 1 Electronics include a 4-axis amplifier for the 4 stepper motors, an LPC-H2148 ARM7 microcontroller with USB interface, limit switches to sense when the X, Y, and Z axes are at the end of their motion ranges, and some (passive) interface components (a breakout board and cables). The cost of the materials required for the Model 1 is about US$2300 before shipping, using the current known lowest cost vendors, and placing all of the orders yourself. It is now possible to order a full kit of parts from a single source, at a slightly higher price than if you place individual orders yourself. Please see below:
