Frequently Asked Questions

How long does it take to assemble the MK4 kit?

You will want to allow 10-12 hours for assembly if this is your first printer kit.


The MK4 has a slightly larger Build volume of  25 x 21 x 22 cm.  Whilst the frames sizes are the same on the MK3S+ and MK4, the additional height in the build volume on the MK4has been achieved due to the geometry of the new extruder on the MK4.

What are the differences between the MK3s+ and the MINI+ ?

The MK3s+ has a Build volume of  25 x 21 x 21 cm.  It has a direct drive extruder allowing printing of more flexible filaments than the MINI+ as well as a higher temperature range to print materials that require higher extrusion or heat bed temperatures. The MK3s+printer will print all of the most common materials such as PLA, PETG, ASA etc as well as some more exotic materials like poly carbs and flexibles.

The MINI+ has a Build volume of 18 x 18 x 18 cm. This printer is a fantastic printer for most materials using a Bowden style extrusion system. All common material's such as PLA, PETG, ASA etc can be printed well with this printer.

What is the difference between PRINTING WITHa flat build plate and the textured one?

The texture of finished part.

They are both made of PEI which grips the plastic extrusion really well when heated and releases it when cooled.

Textured build plate produces a textured finish on the bottom of the part that is printed.

Flat build plate produces a flat finish. With care, this can be a very flat smooth surface.

Is there a warranty?

Yes,  there is a 1 year warranty on all parts. 

Typically, Original prusa printers have a very low return rate as all the parts are tested in the factory before being sent.

We have found that less than 0.5 percent of printers have an issue that is caused by a faulty part in the kit.

Can 3D Print Specialist repair my printer?

Yes we repair PRUSA printers. If you have any problems then send us an email and we will help.

Can my printer get delivered to a Parcel locker?

Parcel lockers generally are too small to fit the printer kit box.

Who are our printers shipped with?

Our delivery partner Australia Post delivers the majority of our printers as well as other products.  All printers shipped with Australia Post are with the Australia Post + Signature service.

How long does shipping take?

We typically ship MINI+ printers and MK4 kits within 1 business day from purchase. Australia Post will provide a delivery ETA once the shipment is processed at their distribution centre. Australia Post Parcel delivery estimates can be found here.

Can I pay by bank transfer?

Yes, we do accept direct deposit payments including instant real time payments via Osko with our PayID.  If you fill in the contact us form with the details of what you would like to purchase, we will email you through a Tax Invoice with the direct deposit and PayID payment details on it.

What maintenance does the MK3s+ require?

In our experience, the main ongoing maintenance required for the MK3s+ printers is to clean the rods with a cloth and then lubricate them with the supplied grease.  The frequency at which this should be done depends on the printers usage, however we would recommend that you do this at least monthly.  For further information on maintenance of the MK3s+ please refer to page 68 of Prusa‚Äôs 3D Printing Handbook

After building THE MK3S+ kit, if I am having trouble with the X-axis length, what can I do?

After you have built the printer, it is a good idea to use a light machine oil to lubricate the bearings before you setup and calibrate the printer. Simply place a small amount of oil on the rods and then move the axis by hand slowly along the rods to each end. The rods can have a coating on them from the factory that restricts movement and creates errors during calibration if the oiling process is not done.

Note: Yes, you should clean the rods and re-oil them periodically. The frequency will depend on how many prints you do, but we suggest at least monthly.

If I purchase an assembled MK3S+printer, is it already calibrated?

Assembled printers are calibrated prior to shipping, however sometimes the Z height requires re-calibrating after a printer has been moved.  Please refer to Section 6.3.6 of the 3D Printing Handbook that comes with the printer which explains how to Calibrate the Z height.  Additionally, the first layer height will need re-calibrating for any additional steel sheets that you use on the printer.  The printer allows you to store the first layer heights for different sheets.
