Ever heard a company giving out a sample of the product it can 3D print for you? Stratasys is one such company and Stratasys J750 is one such 3D printer.

There is a “Get a Sample,” tab on the webpage of this printer’s website. Clicking on this tab opens up a new webpage wherein you need to fill a form and request a sample.

Reading in the paragraph that is mentioned besides this contact form would tell you a lot about this printer.

The J750 Digital Anatomy Printer is recreating the look, feel, and function of actual human tissue with true haptic feedback, meaning the printer manufactures a specific type of medial part.

The material choices that the company gives to you for manufacturing part or functional prototype are:

  • GelMatrix is gel-like support material. The material works well for easy removal from blood vessels with inner diameters and wall thicknesses as low as 1.0 mm.
  • TissueMatrix is the softest translucent material commercially available currently. The material is ideal for replicating the look and feel of heart tissue.
  • BoneMatrix is a strong but flexible material with memory to maintain its shape for representing bones and connective tissue.

These are the materials you can print using the printer J750 which is based on Polyjet 3D printing technology.

The technology is one of the most powerful 3D printing technology that produces smooth, accurate parts, prototypes, and tooling.

Using this printing technology you can obtain microscopic layer resolution and accuracy down to 0.014 mm.

The printing technology is known for producing thin walls and complex geometries using the widest range of materials available with any technology.

Let’s start the review by knowing some of the features of this 3D printer.

Features

As soon as you scroll a little bit down on the webpage of this 3D printer you see the text,” Cutting-edge realism.”

Just beneath the text, you can find some medial part in hands of a person in a picture on the left and in two hands who are holding it with a medical device.

The printer seems to be bringing in realism in testing as well as perfecting the surgical skills. The support material for this printer is called FullCure 705 which is a non-toxic gel-like photopolymer.

The Stratasys J750 printer is capable of 3D printing up to 6 different materials in a single print, with over 360,000 colors available.

The Stratasys J750 printer relies on the PolyJet Studio software for the preparation of the 3D models and control of the 3D printer.

The Stratasys J750 is a printer that delivers unrivaled aesthetic performance to your brightest ideas and boldest ambitions.

This includes true, full-color capability with texture mapping and color gradients.

It creates prototypes that look, feels, as well as operates like the finished products.

The automatic color mapping from your design software lets you create photo-realistic models from neutrals to neons, shadows to highlights, and much more.

As mentioned above, multiple material selection in this printer means that you can load up to six materials at once.

This includes any combination of rigid, flexible, transparent, or opaque materials and their composites.

Double the number of print nozzles in this printer’s print heads allows you to produce ultra-smooth surfaces and fine details with layer thickness which are in the order of 0.014 mm that is about half the width of a human skin cell.

Prints objects differently

If you are a user who desires full-color capabilities over biomechanical properties, the J750 Digital Anatomy 3D Printer will offer you unlimited possibilities.

Not only can you choose different colors, but also define their transparencies. So, essentially the printer would let you print parts that look like other parts but would be tailormade.

This is a kind of feature that you would not get with any other printer that is specifically made for medical applications. This printer would let you determine textures and finishes.

It would let you create an end product that’s as close to the real thing as possible. And these are all claims made by the company.

Thanks to the poly jet technology that the printer prints with, as well as the multi-material capabilities that come within it that you can 3D print prototypes or medical models in the most intricate detail.

Parts and functional prototypes have a difference in their features

According to the observation done before this printer, animal, cadaver, and synthetic models are known to not accurately represent targeted pathology.

The J750 Digital Anatomy 3D Printer comes with three unique digital materials that are mentioned at the start of this article.

Apart from those materials, this printer comes with anatomical pre-sets that provide ultra-realistic anatomical simulation and biomechanical realism.

Summing them up, the result is a model that feels and behaves like the real thing.

So, with this printer, you can essentially create the anatomy that you need and also mimic specific clinical environments for enhanced learning and development.

Cost-efficient

As mentioned on the website, a reason that is given for the printer to be cost-efficient is that it allows you to produce anatomies that feel and behave like the real thing, it reduces the necessity for the use of synthetic models, animals, and cadaver labs.

What this also means is that a reduction in training and procurement costs will affect you the most if you are a manufacturer that produces mass production of parts.

With that, it also means that the ethical practices would improve because it eliminates the need to test surgical procedures and devices on animal subjects.

Printing Type/Cost

PolyJet technology, the technology on which this printer is based, is renowned for its outstanding realism and breathtaking aesthetics. The technology works on this printer similarly to traditional inkjet printing.

The only difference is that, instead of jetting ink onto paper, a print head jets liquid photopolymers onto a build tray where each droplet cures in a flash of UV light.

Just like every other printer, this one too offers sharp precision, smooth surfaces, and ultra-fine details. But the printing cost is also higher than other technologies like FDM 3D printing technology which has a reputation for producing parts with lower quality than this technique.

Here printing is done also by combining a variety of photopolymers in specific concentrations and microstructures.

J750 is one of the most sophisticated PolyJet systems which can simulate everything from plastics and rubber to human tissue and produce a full gamut of colors.

Using this printer, you can now create prototypes, models, textures, and patterns that are incredibly detailed, and with 1000s of material options to choose from you can incorporate diverse material properties and aesthetics.

The overall printing cost of this printer depends on the infill required as well as the dimensional accuracy in the outcome product.
