GETTING STARTED IN 3D PRINTING

Over the last few years various 3D printers have entered the market at significantly lower price points than ever seen before, making 3D printing more accessible to a much larger group of people. One of the companies producing these lower cost 3D printers is Wanhao and I have been using one of their printers, the Wanhao Duplicator i3 Mini, over the last two months.

The Duplicator i3 Mini is a compact PLA optimized 3D printer, weighing just 7kg, with a print volume of 120mmx135mmx100mm. The i3 Mini is extremely easy to get up and running and setup, it comes completely assembled and all the user needs to do to start printing is plug it in and manually level its print bed which takes a few minutes following the included instructions.

The printer ships with an included 1GB SD card with various printable models preloaded on it, so the user can simply insert the SD card and print as soon as the printer is setup. Below are a few photos of one of these models, a little dragon.

The little dragon was printed using CCTree 1.75mm PLA filament.

I use Cura for 3D print slicing, which is the process of converting 3D models into 3D printable formats. Configuring your slicing application correctly for your 3D printer is extremely important and getting this wrong will result in failed prints. Configuring your slicing application involves setting values inside the slicing application that relates to the characteristics of your 3D Printer, for example print volume, nozzle size, filament diameter, print speed and so on. The values for these settings can be found in the printers’ documentation or by simply googling the printer in question and the splicing application that needs to be configured.

Here are some lessons I have learnt so far in 3D printing which might help anyone new to the process:

– Make sure filament diameter is configured correctly, getting this wrong will result in prints failing rather spectacularly.

– Infill is important, but far less is required than most people think, reducing the infill percentage of a print not only reduces the amount of filament used, but also drastically reduces print times.

– When orientating a model for printing in a splicing application, experiment with different orientations and support configurations, sometimes much better results can be achieved with a few minor changes.

– 3D printing is a slow process and takes much longer than most people think.

– Don’t be scared of getting things wrong and having prints fail, it is inevitable and great learnings can be gained from failures.

I will be posting more in the future about my experiences and learnings in 3D printing, but for now I will leave you with a few photos of something else I printed, a USB\SD card holder, which came out great.

REVIEW – X-RITE COLORMUNKI SMILE

The ColorMunki Smile is a basic monitor calibration tool that works with both LCD and LED monitors. Most monitors do not show colors accurately with their out of the box settings and this tool is used to configure monitors so that the colors shown on the display is as accurate as possible.

This is very important for people who work professionally with photos and video, such as professional photographers and video editors, as they need know exactly what the content they are working on looks like.

My interest in the ColorMunki Smile is for a slightly different reason, I use two 27-inch Dell monitors on my computer, the S2716DG and the SE2717H, and as they are positioned right next to each other the difference in their color calibration was very apparent and abrasive to look at.

Using the ColorMunki Smile is very simple, you plug the device’s cable into a USB port and then start the included software that guides you through the configuration process. The device has sensors on its one side that need to be placed in an area in the center of the screen (as indicated by the ColorMunki Software) and the USB cable is long enough and equipped with a counter weight, so it can easily be hung over the top of the screen and positioned correctly. The software will then start the calibration process that takes several minutes to complete and when done a reference image will be shown comparing the before and after results. This comparison showed me that one of my monitors leaned more into the yellow spectrum while the other leaned into the blue spectrum. This process completely rectified the color discrepancy between my monitors.

At the time of this post the ColorMunki Smile costs $85(USD), making it one of the least expensive monitor calibration tools. It is however a very basic and entry level solution that is most probably not appropriate for professionals who are extremely dependent on their monitors being perfectly calibrated, but for everyone else it greatly improves the color accuracy for most monitors compared to their default configuration.
