Description

This video course teaches you how to make a 3D printer for yourself and calibrate and adjust it perfectly. You will get to know how to solve and prevent common problems and discover alternative solutions to tailor your 3D printer to your liking and needs. You will learn how to assemble parts for your 3D printer and build it with ordinary tools and skills. The course starts off with assembling of the Y-Unit and the XZ-Unit before moving on to the extruder and wiring. Next, you will be shown how to execute some simple calibrations and suddenly you're printing in 3D with your very own 3D printer. By the end of the video, you will be a junior 3D printing expert. This 3D printer used for demonstration in this course is especially designed for easy assembly and use, and gives you a head start in building your own 3D-printers for now and for the future.

Building the Y-unit
4 Lectures 11:40

The base of the Y-unit is built with two M10 threaded rods. A number of nuts on these rods will hold the base together.

Mounting the Threaded Rods and Power Supply
03:09

The Y-motor will move the print platform. The front and back plate will hold the linear rods.

Preview 03:04

Setting the belt tension is important to achieve correct movement without wear.

Mounting the Y-carriage and the Timing Belt
03:01

Wondering how to make a perfectly parallel movement? Take a perfectly flat mirror and adjust the linear rods.

Building the XZ-unit
3 Lectures 09:09

The X axis moves the extruder from left to right. You can just slide them together.

Mounting the X Axis
03:00

The Z axis moves the extruder up and down. This is through some simple assembly steps.

Mounting the Z Axis
03:02

Timing belts are the tendons of your 3D printer. The correct tension will ensure proper movement.

Wiring Up the 3D printer
6 Lectures 20:22

The power supply converts the high voltage to a safe 12 Volt working power for the printer. For your own safety, please follow the steps in this video carefully.

Wiring the Power Supply
04:10

The 3D printer has two main units that can be taken apart for easy transport. For the best print results, calibrate them at a perfectly straight angle.

Assembly of the Main Units
03:06

Messy cabling looks ugly and can cause problems. Organize the cables neatly by making them the right length.

Wiring the Y-unit
03:32

The motors of the Z axis run in a series. Cross-link them to make them work.

Wiring the Z-unit
03:14

There are many electrical connections to be made for the extruder. Follow the step-by-step instructions to prepare the extruder.

Wiring the X-unit and the Extruder
03:11

The heatBed needs a decent cable and a well-positioned thermal sensor. Following these special assembly instructions will help you through.

Calibrating the Printer
6 Lectures 22:32

Magnetic endstops have special issues to take into account. This video will show how to glue in the magnets correctly.

Mount the End Stop Magnets and M5 Rods
03:16

Uploading the Marlin firmware to the RUMBA controller is easy with Arduino...if you know how to do it.

Software and Communication
03:20

Mounting the E3D hot end requires some special steps. You will need to heat it up; this is why you had to first finish the wiring and install the software.

Preview 03:40

This special extruder construction requires that you test the grip on the filament. If needed, you have to quickly reassemble the extruder.

Test and Mount the Extruder
03:43

The movements of the printer should be as close as possible to their software values. This is done with some simple measurements.

Calibrating the Movements of the Printer
04:30

The print platform should be perfectly aligned with the nozzle to get a good first layer. This is done by turning the three screws in such a way that a simple piece of paper just fits underneath.

Setting the printer and filament settings is the basic preparation in Slic3r.

Filament and Printer Settings
03:07

Print settings depend on your personal taste and the requirements of the object to be printed.

Print Settings
03:06

The first layer is the most important one. If the nozzle is too high, the print won´t stick, and if it´s too low, you might damage your print platform. Learn what the first layer can tell you about improving the quality of your printer.

First Layer
03:08

Printing in two different materials requires additional workflow. Learn all about it.

Sometimes, extra drivers have to be installed. These are needed for connecting with the Arduino board. Most Linux distributions don't support the default baud rate of 250000. There are three ways to solve this.

Software Issues in Windows, Mac, and Linux
03:06

Layer shift is a nasty problem that causes a non-aligned printed object, which is of no use to you and can be thrown away. The X or Y stepper missed some steps while printing, producing unusable objects. There are three common causes for this problem, which can all be easily solved.
