【3D Printing Information】 Ultimaker 3 Unboxing and Hands-on Review!!

I'm sure everyone has seen a lot of information about the Ultimaker3 3D printer recently. If not, you can check out our article [3D Printer] Ultimaker 3: The New Generation of 3D Printers.
But what will it actually be like to print with it? Hehe~ Let 3DMart tell you.
After unboxing the machine, the first thing to do is, of course, to re-print samples that we always thought "would be even better if printed with a powerful dual-nozzle 3D printer" using the Ultimaker3.
What's the use of dual nozzles? Why can only Ultimaker3 achieve it? Let us tell you all at once!


The first thing we re-made was ski goggles. As you can see, unlike single-nozzle machines, the support uses water-soluble PVA material~

After printing, depending on the amount of support, just put it in water for a period of time, and the support will naturally dissolve!



After taking it out of the water, rinse it with clean water, wait for the object to dry, and it's done!



Additionally, to reduce dissolving time, you can remove most of the support before putting it in water.
This is the PVA dissolving in water. Seeing the supports that used to be a pain to remove, hard, and would scratch your hands, turn soft and squishy gives an indescribable feeling of comfort.



Friends who have used FDM printers know that the marks left after removing supports are often unacceptable.



But look at this support surface after dissolving in water. Its delicacy will surely make you wonder, "Is this really made with FDM?!"



The second major revamp is the bicycle frame, which was previously printed with nylon and carbon fiber. Why do you think dual nozzles are needed?

The holes around the object are meant for inserting brackets later, but the problem with a single nozzle was that supports deep inside were difficult to remove, and removing them might leave some marks, making assembly difficult.



With a single nozzle, you would definitely have to sacrifice a surface for supports. Now, with water-soluble supports, even the support surface can have perfect surface quality.



The third item we started making is the bone model. In terms of 3D printing difficulty, this is definitely one of the top ones!



Why? Besides the complex shape, there are many hollow parts encased inside, which even light-curing machines might not be able to achieve, let alone a single-nozzle one!



Water-soluble supports can fully support every corner of the object, no matter how complex it is, resulting in perfect performance!



What else can dual nozzles do besides water-soluble support? Of course, dual-color printing! From now on, objects will no longer be limited to a single color, and unlike changing colors mid-print, which only allows changes in height.

The two colors are distinct and blend perfectly! Why can Ultimaker3 easily achieve such excellent quality?
The answer lies in the newly designed nozzle system. Common problems with previous dual-nozzle machines include:
1. The height of the two nozzles is difficult to adjust, and the nozzle easily collides with the object.
2. When the print head moves, the nozzle that is not printing is prone to stringing and oozing.
Ultimaker3's unique patented design:
1. Improved nozzle tip, adding a flow resistance design to prevent oozing and stringing when the nozzle moves.
2. Automatic nozzle lifting system, the second nozzle will automatically raise when not printing to avoid affecting the object.
Combined with Ultimaker's consistent stability and high quality, this ultimately leads to perfect printing results!
