How to Add Fans and Lighting to Your RepRap 3D Printer

Fans are widely used with RepRap home 3D printers; they help keep critical parts like the hot-end thermal insulator cool, and can also assist you with a smooth printing process. [more…]

How to Wire Your RepRap 3D Printer

Even with a full, ready-to-build RepRap kit of parts, you will always have to connect various components and devices to the electronics — and sometimes that means crimping connectors or doing a little [more…]

How to Configure the Firmware on Your Prusa i3 3D Printer

Before you can use your RepRap 3D printer, you will need to configure the firmware. Here is a short guide to getting the Marlin firmware running on your RAMPS electronics. [more…]

How to Set the Switches on Your Prusa i3 3D Printer

The Prusa i3 3D printer has switches to let the electronics know when the X, Y, and Z carriages are at the home position. These can very often require an inverted signal for the electronics to understand [more…]

How to Upload the Marlin Firmware to the RAMPS Electronics on Your Prusa i3 3D Printer

You will need to upload the Marlin firmware to the RAMPS electronics on your Prusa i3 3D printer. When you've made your printer-specific setting changes to the file, you can save the file. Then check to [more…]

How to Fix a Blocked Hot-End or Extruder on Your 3D Printer

When you get a hot-end blockage or your extruder's filament drive fails on your 3D printer, the signs are usually obvious: The stream of plastic starts to lessen, and then stops; the printer keeps trying [more…]

How to Cool Extruders with Fans on Your 3D Printer

The golden rule about 3D printing extruders: Use fans. When you start experimenting with printing ultra-tiny objects with fine details or printing objects at great speed, you quickly discover an interesting [more…]

How to Configure Slic3r on Your 3D Printer

When Slic3r has been installed successfully, you can go about configuring it. Before an object can be sliced up into layers for 3D printing, Slic3r has to know a number of key settings for your particular [more…]

How to Level the Print-Bed on Your 3D Printer

The first order of business here is to make sure the hot-end nozzle on your 3D printer is a set distance away from the print surface and that your printing surface is flat and level. [more…]

How to Calibrate the Extruder Distance on Your 3D Printer

You will need to set the extruder calibration on your 3D printer. Before you can calculate the last value, you need to ensure that the correct amount of plastic is extruded for a set extruder distance, [more…]

How to Print a Simple Cube on Your 3D Printer

This is an exciting moment, but don't get overly ambitious for this first 3D object. Instead of jumping in with a complex object at this stage, try printing something easier — like a simple cube. [more…]

10 Ways That Rapid Prototyping Will Disrupt Traditional Manufacturing

Major transitions rarely happen without stress. Additive manufacturing offers exciting new capabilities, but it also abbreviates the production process that underlies modern mass manufacturing — creating [more…]

10 Examples of Direct-Digital Manufacturing and Personalization

Additive manufacturing is not a futuristic technology; it's already in place and in use across many industries from medical implants to aerospace technologies. As material options expand and complexity [more…]

10 Impossible Designs Created Using Additive Manufacturing

Many of the designs made possible through additive manufacturing are “impossible” using traditional manufacturing technologies — or, if they're not outright impossible, they're at least so expensive or [more…]

How to Edit the Marlin Configuration.h File for Your Prusa i3 3D Printer

Editing this file is the heart of the Prusa i3 3D printer configuration process. This section provides an overview and specific recommendations. Keep in mind that there is a text file in computer programming [more…]
