Lore #8 - You don't need to be an engineer to 3D Print

There's a new poster coming to create a series of 'talking points' based around 3D Printing in the Classroom and while its from the perspective of our small rural school in South Taranaki New Zealand - we've already posted a series of talking points about this - which you can click on the link below about each topic for further information or details about how it applies to us.

#1 You don't need more than one printer at your school to print your student projects.

#2 All of your 3D Printing projects don't need to be 3D Printed - there are other options!

#3 There's a range of non-standard filaments that are available to enhance your prints

#4 Juniors can create, design and develop a range of 3D Projects 

#5 The teacher doesn't need to be an expert in 3D Printing

#6 You have options to enhance your printing projects with options

#7 Engage with the wider community with your projects and resources

#8 - You don't need to be an engineer to troubleshoot 3D Printing projects.

We've been tracking our 3D Printing over a number of years with the first printer at our school operating in 2014.   The early machines that we had were complex and 'relatively' reliable.   When we had problems with the printing with the machines (when they would print incorrectly) it could at times require significant teacher input to correct the machines.

Following our early machines we went to a series of other branded machines that were significantly more reliable Ultimakers (2015-2022) in various version and updates.  We went to Snapmakers in 2022 and then last year 2025 we switched to (primarily) Bambu.

It has never been our intention to endorse any particular products or processes via this site - however we would like to point out that everything here is created by students and staff (where noted) and the intention is simply to share what we do so that other people can get inspired and have a think about how that might apply to themselves or their school.

With that in mind the Bambu H2D that we are using has taken things to another level.   Since August last year essentially everything on this blog has been printed off the one machine.   The machine itself has had to be greased (the axel) however this was relatively simple.   The inbuilt protection against a miss print has stopped it a handful of times.   The changing of the filament etc is extremely simple.  We have yet after seven months to have any significant issues with the use of the machine with prints ranging from 30 minutes to forty hours.

The print shown with this post took forty minutes but crucially the print itself is how it came off the machine - the sunk in lettering that is visible was completed without any support or material needed to be removed.  If you note the smallest name, Penelope, this has been completed and is currently 3mm in height.   This is something that we have seen with this machine.   It is also noticeable that the amount of rafting or support plastic with this machine for general prints (such as the cow) this has been greatly reduced.

As the technology has evolved with the 3D Printing the scope, accuracy, reliability and potential has continued to improve the outcome for students using the tools available.
