Formlabs Form 3B has a footprint of 405 × 375 × 530 mm. And, it offers a build volume of 146 × 145 × 185 mm which is pretty decent for dental parts production.

Hence, users can create multiple parts instead of one. All the benefits are wrapped in its 17.5 kgs of weight.

So, you can easily move it from one place to another. This makes this 3D Printer a lot easier to manage as well.

With a temperature control compartment, you can expect high-quality parts, suitable for the best application.

It enjoys an operating temperature of 35 degrees Celsius. Alongside, it has one laser processing unit.

The laser strength is pretty remarkable with a 405 nm wavelength, 250 mW power, and a laser spot of 85 microns for higher resolution.

Moreover, the auto-fill resin tank further makes it convenient to complete the task faster and with the minimum effort possible.

There is one resin cartridge. Overall, the 3D Printer has been designed with close precision for attaining high-quality dental prints.


When compared to the Form 3 3D Printer, this one is a little expensive. Unlike Form 3, whose basic package begins at $3,499, Form 3D basic package starts at $4,999.

Similar to its predecessors, you get options to choose from the list of other components to add more room for innovation and creativity.

In the basic package, you receive a Build, finish kit, and tank along with the 3D Printer. However, you can choose for Form wash and cure station by paying some extra bucks. This could cost somewhere around $5,999.

First Impressions

The 3D printer is clearly a work of great precision. Right after you lay eyes on Form 3B, you can fall in love right away.

The sleek design with orange and grey color structure offers a resonance to the family of dental 3D printers offered by Formlabs.

However, it never ceases to impress us through its looks and the way it’s wrapped safely inside the packaging box.

Yes, the company takes extra care for ensuring the machine reaches you safely. Completely assembled, the 3D Printer is easy to set up for the first time. Hence, offering users a hassle-free experience.

And, not to forget, its compact design gives users one more reason to opt for this 3D printer.


As mentioned before, setting up this printer for the first time won’t take long. Along with the packaging box, you receive the manual for connecting the different components together and starting the print following the same.

It comes completely assembled. Therefore, there is no need to invest hours fixing printer parts together. Just turn the machine on, carry few basic steps such as filling material, uploading the CAD design and the rest will fall in place.

Printing Type/Cost

Formlabs Form 3B machine works on SLA 3D printing technology. Like other 3D printing processes, this technology also creates the models, one layer at a time.

The laser is used for curing the liquid polymer which solidifies as soon as the laser falls on the set paths or the cross-sections. At first, the build plate is staying just one layer away from the liquid surface.

After the layer is done, the build plate moves with a layer difference, making room for the next layer. The same process continues until the part is completely printed.

In terms of cost, SLA is not the cheapest 3D printing process available. However, the print quality and precision it offers, help it justify the cost effortlessly.

Also, Form 3B, working with biocompatible dental resins, can seem a bit expensive than the usual SLA 3D Printers.

However, to accurately calculate the cost of printing each model, you must refer to the various factors. It could be the print geometry, design, layer height, and more.

Print Quality
