How to manually add a brim in CAD to improve bed adhesion for 3D printing

This is a short how to guide for creating your own brim on a 3D model in CAD to prevent a model from coming loose from the print bed. This can come in handy in case your slicer software does not include a correct brim suitable for your part.
When 3D printing taller objects which are relatively narrow, the printed object can possibly come loose from the bed, resulting in a failed print. The higher the object becomes, the larger the risk, due to to increasing mechanical advantage for larger height to width ratios.

Dobot AI Starter Review

The AI Starter is a Robotic Car based on the well established Arduino architecture. It is primarily intended to be used in education for programming, automation and robotics.
After posting a couple of videos on the Dobot Magician Robot I was contacted by a local Dobot supplier Dobot.nu. They asked me if I would like to have a look at some of the other products Dobot has on offer.

In this article I will have a look at the AI starter kit they sent over for review. I will cover the assembly of the kit, programming and a mini project with a tipping bucket I designed, to demonstrate the expandability of the platform.

How to Make a Vision System for the Dobot Magician with the Pixy 2 Camera

Vision systems and robot arms are used in many modern production lines. With the availability of cheap vison cameras for consumers it has now become possible to make your own vision system controlled robot arm at home.

This article describes how to add a vision system to the Dobot magician robotic arm, allowing it to identify parts automatically and place them in a designated drop off location.

3D Printing with Verbatim Polypropylene: Initial Impressions Review

Polypropylene (PP) is a material that is used in a variety of applications like packaging, automotive industry, furniture, et cetera. For use in 3D printing however, it is not nearly as popular as PLA, ABS or PETG.  This might be because PP filament is not readily available at most resellers. Also, it is difficult to find information online about requirements for the printer and process settings which would be needed for a successful print.

In this article I will share my 3D printing experiences with the 1.75 mm PP filament made by Verbatim and hope to shed some light on how to print this material on a typical 3D printer (heated bed required!). Continue reading “3D Printing with Verbatim Polypropylene: Initial Impressions Review”

Slic3r Prusa Edition Variable Layer Height

Stepped surfaces in 3D prints have been around since the dawn of 3D printing using the FDM process. The question is how to get rid of the unattractive steps them without drastically increasing print time. In this article I will cover a new feature in the Slic3r Prusa Edition that will allow you to tackle this problem in an interesting way. This also works for 3D printers which are not made by Prusa. I will test the feature with my Flashforge Dreamer. Continue reading “Slic3r Prusa Edition Variable Layer Height”

Dobot Magician First Impressions Review

Dobot Magician First Impressions

Dobot has recently released the second version of their robotic arm. The Dobot Magician can actually be considered a learning platform for robotics, programming and manufacturing methods for makers. It includes end effectors for pick and place operations, 3D printing and laser engraving. It is positioned as a robotic arm for educational purposes, light industrial use and hobby projects at home.

Z-Wave: Controlling Light with a motion sensor

Fibaro Motion Sensor

 

Z-wave modules offer great flexibility and a relatively inexpensive way for automating just about anything in your home, from lights to the garage door. In this article the installation process for a light operated by a motion sensor is covered. This is one of the most basic applications of Z-wave automation and might be a good project to if you are considering to start with Z-wave. Continue reading “Z-Wave: Controlling Light with a motion sensor”

Dual Nozzle X and Y offset calibration on Flashforge Dreamer

When using a dual extrusion printer it is important to calibrate the distance between the nozzles in X and Y direction. A properly calibrated printer will produce parts without a visible shift between sections printed with the left and the right extruder. In this article I wil discuss the use of a calibration program to find the offset between the nozzles on the Flashforge Dreamer.
