Upgrading The Blue Prusa – How-To Guide

Nick — Tue, 14 Feb 2023 21:30:51 +0000

The blue Prusa we built for the assembly guide blog has been working nicely for a while now. There is always room for improvement though so we’ve decided to showcase this little upgrade that has proved to aid in print quality on our other Prusas.

Reasoning

To obtain the best print quality, especially when your model has overhangs, you need to cool the printed material as soon as possible after it leaves the heated nozzle. While the standard Prusa duct is adequate for most jobs, gains can be had by replacing it.

This air duct assembly by teookie on Prusa’s Printables.com was designed using CFD analysis to predict air flow characteristics and is designed to replace the standard Prusa ducting. Instead of the air flow coming from one just the front of the standard duct, the replacement part has the flow split into two and directed from either side of the print area. When printed in a high temperature filament such as PETG or ABS it is able to withstand the heat of the hotend.

Conclusion

This is a simple upgrade for anyone who owns a Prusa Mk3S or MK3S+. It requires no wiring or special tools. In fact it uses only some of the spare nuts and bolt that you will have received with the printer. The cost is only a few cents worth of filament and about 15 minutes of your time.

I’d recommend doing this for anyone with the Prusa. Click on the screenshot above or the Printables.com link below to download the 3D models.

I’ll have more for you next week! Bye.

Prusa i3 MK3S+ Build Guide – Part 8 – Final!

Nick — Tue, 08 Nov 2022 21:30:00 +0000

This is it! The final installment of our Prusa i3 MK3S+ build guide. All that’s left to do is plug in all the cables and run some calibrations and the 3D printer will be ready for action. A video version of the build guide is linked below on our YouTube channel.

Many have trouble with the wiring process so I have attempted to highlight as well as possible where all the connectors plug in.

I hope this has been useful to those that have used this as a supplementary guide to assist with assembling your Prusa MK3. I’ll have more next week. Happy printing!

Now that the 3D printer is fully assembled and the Preflight check is complete, you can run through the calibration process. Plug the printer into mains power and turn on the switch. You’ll be prompted to run the automatic calibration sequence which takes around ten minutes and is super simple. The final step is the Z height calibration shown in the video below.

If you’ve been following our Prusa build guide, no doubt you’ve been hanging on the edge of your seat waiting for our next installment. The long awaited wiring guide is now here.

Use this guide in conjunction with your included Prusa MK3S+ guide to build yourself an nifty 3D printer. This installment only deals with the cable routing so stay tuned to see how to plug the wires into the motherboard.

Fixing A Clogged 3D Printer – The Cold Pull

Nick — Tue, 18 Oct 2022 21:30:16 +0000

Once in a while everyone who uses a 3D printer will be faced with a clogged nozzle. It’s frustrating when you come back to a finished print and the top of your model is missing but it is a pretty simple process to unclog and start again.

Before going into the treatment, let’s touch on what causes clogs in the first place. There are a number of ways the nozzle can become clogged such as dust or contaminants from the atmosphere getting into the print head, contaminants in the filament itself or possibly parts of the 3D printer that have worn off and fallen into the mix.

We had a clogged nozzle on one of our Prusa Mk3s recently so I thought it’d be a good opportunity to document the unclogging process to help out others in the same pickle.

Follow the step-by-step pictorial guide to get your 3D printer back up and running.

The cold pull is your friend when faced with a clogged nozzle.

Gallery - Pictorial Guide To The Cold Pull

The cold pull isn’t always effective in getting rid of clogs but 95% of the time it’ll do the trick. I’ll try to document the process of dealing with more stubborn clogs if we come across one again in the future. For now, all is well with the printers.

Renovations are underway at the new house at the time of writing. The living area needs the most attention at this point so that we can move in at the end of November. The new Lannix design workshop will be the next priority after that’s done. There has been a deliberate slow-down in CAD and 3D printing jobs since my energy needs to be focused on getting the house ready. I’ll still be posting regular blogs though so until next week, happy printing!

Prusa i3 MK3S+ Build Guide – Part 6

Nick — Tue, 13 Sep 2022 21:30:12 +0000

Carrying on from last week’s guide to installing the LCD screen, we have the heated print bed and power supply unit (PSU). Though not quite as short as last weeks update, this one isn’t too taxing either. This is good because the wiring guide that follows can be a bit tedious experience so enjoy this!

I’m not sure when the next part will be published yet but it shouldn’t be too long to wait. Until then!

A nice short post on the Prusa i3 MK3S+ build guide. This weeks we’ll go through the simple process of installing the LCD screen onto the front of the 3D printer. Follow the pictorial guide in the gallery below to see what to do.

Stay tuned next week for the sixth part of the build guide where the heated print bed will be installed.

Prusa i3 MK3S+ Build Guide – Part 4

Building the extruder

Welcome to part 4 of the Prusa build guide! This is a big one!

It’s now time to assembly the business end of your machine. The extruder assembly is where the filament is melted and placed onto the print bed to become your 3D printed part. Luckily Prusa have wired up all the necessary parts with plugs so that all we need to do is assemble them.

I would say that the build gets a little more challenging here due to the smaller and more numerous parts used as well as dealing with cable routing that can get in the way of everything fitting well if not done right.

So, as mentioned before, this is a big update split across five galleries but there should be enough covered to assist you in assembling your MK3S+.

Check out the previous parts of the build if you haven’t seen them already. The next part should be published next month for those who want it.

Building the X and Z-axes

Welcome to part 3 of the Prusa build guide! Because this is the fourth Prusa i3 in the Lannix3D workshop, we have reproduced some of the parts with a nice blue filament to distinguish this printer from the others. Prusas come from the factory with 3D printed parts, some of which are coloured orange which is their signature colour.

Prusa has made the CAD files for these parts available for download from their website which makes it easy for customers to customize their machines.

The X-axis assembly stage sees the first of these coloured parts utilized.

Building the Y-axis

Moving on from the first post where we assembled the 3D printer’s main frame, it’s now time to build and install the Y-axis carriage.

Incidentally, this is where I’ve noticed a difference between this MK3S+ and the earlier MK3S which is the brackets that hold the linear bearings to the underside of the carriage. The MK3S employs zip ties to hold them together!

Building the main frame

Prusa 3D printers are considered to be a reliable workhorse machine suitable for mass producing parts in a small business. Popular with hobbyists and businesses alike, we can vouch for their reliability and performance. This is our fourth Prusa machine and to distinguish it from the rest we have decide to replace the standard orange pieces with some pretty blue parts.

They are available either pre-assembled or in kit form. We prefer to save some money on import duty and the cost of the printer and build them from a kit!

What’s in the box!

Building the kit can be tricky for some so we thought it would make an interesting article to document the process and publish it in our blog.

The galleries below are meant to compliment the Prusa build guide and we hope that you enjoy seeing what’s involved in assembling a 3D printer and maybe gain an insight into how they work.

This is part one of what will become a multi-part guide and shows the assembly of the main frame of the 3D printer.

Enjoy!
