It is always a fan to create something new. To use what was already developed and is close to you, available for free or at low costs and improve the rest to create something new. This is what we did. We re-designed the 3D-printer – to prove that you can do that by yourself. The result – a new 3D-eVo printer… look below at the design.
It was in winter of 2018. The weather was not a perfect – with a lot of rain, cold – so it was not to go type of wether. Of course, you can spend time using your rolling machine or bike trainer – but it is not developing your imagination or improving your skills. You can play games with your family. Spend time with children… unless they are not sleeping already. You can as well design something new… This is what I decided to do.
I wanted to build a printer, based on Hypercube Evolution (I own one and it is great) – but reducing some costs – still keeping high quality and perfect results for printing. Standard Hypercube costs are around 900 Euros – if you want to use 32-bit motherboard with touchscreen and good quality components – with printing size 300x300x350 (mm) – it is medium cost. You can easily go to 1200 Euros.
The idea was to replace the frame (normally aluminium type) with something less expensive – making the printer looking perfect for a room – even a living room. And reduce costs. I was searching on the Internet for some ideas and found that you can actually use the IKEA table as a frame. In 2017 I have created a prototype – using my old Geeetech printer – designing parts, connectors etc. This was fun but I made some mistakes – which I identified. The second round was to fix those issues.
Creating something new is always valuable thing. Making things better – as well. Sometimes it is more important to improve something – than create something new what would not work as designed or expected.
Look around – maybe there is something to improve…
The initial design was build using extra aluminium frame elements (leftovers from the previous build) – the idea was to build a printer with closed chamber – to be able to print in more harmful plastics – like ABS. It was important as well to control humidity inside and as well to keep a stable temperature. This is why the printer chamber was closed with plexiglass. As of firmware for printing engine, I decided to use open-source Klipper firmware – which was perfectly fitting Geeetech hardware. It is working well… – maybe not perfect – but good enough. Of course – there were some issues with elements to create a frame – I did use mostly standard Hypercube elements for moving parts. Those parts fit aluminium frame – 30×30 – but not really Ikea table. In the end, I was satisfied with the final result – but I was looking for improvements. And I wanted to build something that would look better. This is whe it all started.
First – change of the printing material.
Initial printer parts were printed mostly in PETG and ASA. Good and strong materials – but not really elastic. The printer should be stable but as well it should be able to limit printing noise – it should as well allow for some micro misalignments. Still – parts which should be strong and stiff – should use PETG, but the rest should use something more flexible. I decided to use Flex PLA from REAL – and this was a very good decision. This plastic is strong, really strong. It is elastic – but not too much. It is very easy to print and all the printouts were very accurate. It is great plastic – one of the best if you need something that is looking like a normal mass product. All frame connectors were printed using this plastic. It is really reducing vibrations. Additionally – motor holders for XY were as well isolated with elements printed in flex. This reduced the noise level. And this was the first good decision.
All parts were designed keeping in mind the type of plastic. As I have mentioned – not everything was designed from scratch. I have found many parts already on the Internet – shared with the community. This is what you normally do – you design and you share. I have designed the box for electronics – which you can find on Thingiverse at THIS address. If you look at the account there – you can find as well some other interesting items developed.
It is important to have good electronics. In this situation, it was decided to use Lerdge X motherboard with some extensions. To the mainboard, I have added a heated bed module (very good – able to support up to 300W at 12V), a very accurate sensor for bed levelling, power module to prevent loss of work when power is down and as well steered LED Light. All electronics were placed in the box. I have designed as well a new way to feed the printing head – so it is easy now to remove whole printing head – just disconnecting two 10 PIN connectors.
All that was closed in nice IKEA design – as you can see in photos – it is very compact, not very noisy and it is printing smoothly all parts. Calibrated with the calibration tool.
What is importan – it is all managed by the colourful touchscreen – and the way of management is very easy and basic. You can easily start printing from memory stick or memory card, you can adjust the height during the start with one or two clicks – so your printed products would stick perfectly to the heated bed. It is all very intuitive and easy to manage – using 32bit motherboard with extra WiFi capabilities.
You can see the quality of the test print on our Thingiverse account – look at this dragon! The dragon was printed as the test on this printer – using white PLA plastic.
It was printed in 4 pieces at once – so quite risky – took whole night – and then it was polished manually – to get good results when painted. Then all was painted manually with normal acrylic paint. You can see the result.
And now the most important!
We have this printer now on sale – this is a private sale at the costs. It is including 1-hour training in printing and delivery in the Netherlands – eventually to Germany close to the border.
Price for this printer is 450 Euros. It is coming fully calibrated, tested and it is suitable for printing in PLA and PETG plastics. ABS – possible but not recommended.
If you are interested – please contact with us at firstname.lastname@example.org – we would respond in 24 hours. Only one person would be selected – so please write a few words why you want this printer. As this is private sale – there would be no invoice, but I hope you would enjoy great printing quality from this model. You can as well build your own printer using our parts which we would share soon on our site.
