3D PRINTING REVIEW – CCTREE CARBON FIBRE PLA FILAMENT AND 3D PRINTER UPGRADES

IMG_7750

The CCTREE Carbon Fibre PLA filament is a 1.75mm PLA filament infused with Carbon Fibre, resulting in a filament that can produce prints that are much stronger than standard PLA. This filament is thus ideal for high-wear and load-bearing prints.

This higher durability does come at two significant tradeoffs. Firstly CCTREE Carbon Fibre filament costs approximately double what CCTREE standard PLA filament costs. Secondly and probably the largest problem with this filament is that it experiences significant bowing as it cools compared to standard PLA filament.

This bowing can result in prints separating from the print bed, which occurred more than once during my testing, and below is a picture of the consequences of one of these bed adhesion failures.

I found that the Carbon Fibre filament worked best when printing smaller items as the bowing occurred much less on a small surface area.

Here is a picture of some items I printed using the Carbon Fibre filament to upgrade my Wanhao Duplicator i3 Mini.

On the left in the image is a filament guide that prevents the filament from grazing against the printer body and ensures smooth filament movement. On the right are bed stabilizers that prevent unwanted bed movements that result from slight shifts in the bed leveling springs.

I also printed a tool caddy using the Carbon Fibre filament, and this was the largest item I printed successfully using the filament. Here are some photos of the tool caddy.

As can be seen in the Wanhao logo on the tool caddy a good level of detail is possible using the CTREE Carbon Fibre filament. Also note that all prints required minimal cleanup, with little to no stringing occurring.

Here are a few pictures of the upgrades installed.

The CCTREE Carbon Fibre PLA filament is a very useful filament for printing functional parts that require a level of robustness not offered by PLA, but it does require more care and tweaking to print successfully. It is an excellent filament, just not one for beginners.

On a side note, I recently installed a silicon sock on my printer’s hot end. This is a simple and inexpensive upgrade that offer numerous benefits such as helping to keep the hot end temperature constant and keeping the hot end clean. It also a safety measure and prevents burns from accidentally touching the hot end. It is definitely a worthwhile upgrade considering the minimal investment required.

3D PRINTING REVIEW – CCTREE CARBON FIBRE PLA FILAMENT AND 3D PRINTER UPGRADES

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.
