- Embodi3D's Review of the Ultimaker 3 Extended FDM printer for medical 3D printing. The video starts with unboxing and setting up the printer and then move onto to 3d printing several anatomical structures. The Ultimaker 3 line of 3D printers have a large build volume and dual extruders, which allows use of water-soluble support material like PVA (polyvinyl alcohol) for 3D printing. This is very promising for medical applications because anatomic 3D prints are usually large and have complex geometries. This is a detailed review that discusses the setup and real medical 3D prints from this printer. Pros and cons are discussed in detail. This review is a must for anyone considering purchasing an Ultimaker 3 Extended for medical 3D printing.

The Ultimaker 3 Extended is the subject of this review by Dr. Mike. Presented by embodi3D.com, this video provides viewers with helpful information for deciding if the Ultimaker 3 Extended is adequate for their needs. Dr. Mike begins by unpacking the box and setting up the device. The focus here is on medical 3D printing beginning with unboxing and setup, all they way through printing several medical models.
This analysis measures the potential of the Ultimaker 3 Extended for 3D printing medical models. As Dr. Mike explains, the complex geometry and large size of 3D medical models makes printing them more complicated than 3D printable engineering projects.
The Ultimaker 3 Extended is a fused deposition modeling or FDM 3D printer that utilizes two extrusion cores. Taller than the regular Ultimaker 3 by 3.9 inches in vertical build height, the dimensions of the Ultimaker 3 Extended are 8.5. x 8.5 x 11.8 inches (21.5 x 21.5 x 30cm).
The cost varies among the supported printing materials, which includes filaments made of nylon, PLA, ABS, CPE, and PVA. Solubility in water makes PVA an excellent option for support material in 3D printed models, as it can easily be removed by being submerged in water.
The Ultimaker 3 Extended is ready to print layers as thin as 20 microns after some minor assembly. In addition to Ultimaker 3 Extended itself, the retail price of $4300 also includes 2 rolls of filament, a power cable, a glass build plate, and more.After a walkthrough of the steps to setting up, Dr. Mike demonstrates the capabilities of the Ultimaker 3 Extended.
Dr. Mike uses silver PLA with water-soluble PVA support for the lumbar vertebra done in the first example and the celiac artery done in the second example. Both of these small models are successfully 3D printed by the Ultimaker 3 Extended!
An obstructive piece of filament causes an error between examples 2 and 3, but this is overcome.
A full-sized brain is the third example. Success on this model is delayed until the 7th attempt due to mishaps like running out of materials during printing, build plate adhesion issues, and a possible software crash.
The final example is a tall lumbar spine model. This effort is also plagued with errors, including a near catastrophe where the glass plate is nearly ejected from the printer! After this happens twice, Dr. Mike aborts his attempt to print the lumbar spine model.
Using the Ultimaker 3 Extended led to a success rate of 21.4% (3 successes/14 attempts). Dr. Mike lists the large build volume, inexpensive material required, availability of water-soluble material, and good performance on short prints as pros of the Ultimaker 3 Extended.
The unreliability on tall prints, slow speed on full build volume prints that can take up to a week, high maintenance and supervision requirements, and glitchy firmware are the cons Dr. Mike gives for this 3D printer.
The magic of creating 3D printable medical models begins with the right device! This review on the Ultimaker 3 Extended and Dr. Mike’s other resources on embodi3D.com can help viewers make the best choice when choosing a 3D printer.
