For many decades, mold making and casting were the go-to methods to produce realistic prototypes of smaller plastic goods. Often referred to as Room Temperature Vulcanization (RTV) or silicone molding, this is the process of producing a master part and making a flexible mold off that master. Then, the mold is filled with a two-part urethane resin, which cures into the shape of the mold. This produces a part that exactly mimics the original master’s shape and surface finish. This process is extremely versatile and is in use in many industries. Still, it requires a skilled model maker to produce a master and understand the proper molding techniques to achieve the desired result. Today, 3D printing is changing the way RTV molding is approached and no 3D printing technology is better suited for the task than Stratasys’ PolyJet technology. In this article, we will illustrate the process of RTV molding and explore how PolyJet printing can augment the various steps.

We’ve all heard it before – prank, gag, joke, high jinx, whatever you call it, the day for them only comes once a year. You guessed it, April Fools' Day! Commonly celebrated on April 1st in America, April Fools' Day is an annual custom consisting of silly jokes and funny pranks. Believed to have originated in the 12th century, this holiday permeates cultures around the world in different ways and is constantly evolving as technology continues to advance. Since the Stratasys J Series of PolyJet 3D printers can produce hyper-realistic parts, we decided to put it to the test and prank a fellow co-worker.

If you own a 3D production system or have considered 3D printing as a solution, it is important to understand which is more important for your application: dimensional accuracy and repeatability or resolution. In this blog article, we discuss why layer thickness is listed as microns in 3D printing and why that matters.
As we have seen in this blog series, additive manufacturing is becoming commonplace in many disciplines not typically thought of such as architecture and fine arts. Other disciplines, such as science, have benefited from using 3D printing to advance research and understanding by turning difficult concepts into tangible models. In this article of our series, we look at a few examples of this and specifically how 3D printing has been beneficial in Hunter College’s chemistry department.
In 2019, Stratasys announced that their J735/J750 and their J835/J850 PolyJet machines successfully passed the rigorous requirements needed to make them the world’s first and only PANTONE-validated 3D printers. This was a huge hit and manufacturers around the world were rejoicing. Last month, Stratasys launched the newest member of their J-series, the J826, which is also PANTONE-capable. This changes the game for 3D printing as design and prototype colors can now be matched with 100% specificity, making the process from concept to final product even more accurate.

Additive manufacturing is alive and well in the manufacturing disciplines, and as I mentioned in the first blog of this series, it’s also impacting the education sectors. In addition to architecture, additive manufacturing is used in other departments such as the Fine Arts. There are many disciplines that fall under the category of “Fine Arts,” but for the topic at hand we are going to discuss how digital scanning and 3D printing are revolutionizing the traditional means of sculpting and even fashion.

With the design cycle getting shorter each day, having a physical prototype in your hand is more important than ever. SOLIDWORKS 2020 makes it easier to go from design to prototype with the latest enhancements to 3D printing. From visualizing your model, preparing it to be printed and finding a vendor, SOLIDWORKS 2020 gives you some great tools to be able to fully adopt and implement 3D printing to your workflow. It’s all found in the file menu, by clicking File > Print3Ddirectly in the software.

Stratasys just released the newest addition to their J-series family of PolyJet 3D printers, the Stratasys J826, an entry-level printer for the enterprise design world. Just like the J850, the J826 has been created using Stratasys' best-in-class PolyJet technology and is part of the only family of printers currently available that can print full-color, multi-material models in a single print. It provides the same end-to-end solution for the design process and ultra-realistic simulation at a lower price point.

Almost everybody loves chocolate, right? That’s exactly what I was thinking when I was working on some models for our previous Halloween and Christmas candy articles. As I was working on those projects, I came across a surprisingly quick and easy way to apply full-color patterned textures to CAD models for 3D printing on the Stratasys J750 and J850, using SOLIDWORKS Visualize, and had the idea to use this method to make chocolate bars for Valentine’s Day!

Automated Fiber Placement (AFP) is the additive manufacturing process of creating 3D shapes using composite layers of heated resin, which also contains non-metallic fibers. This process can result in 3D printed parts that are two times stronger than steel at one-fifth of the weight (which is excellent); however, the technology traditionally requires million-dollar AFP systems (which is not great). Desktop Metal has recently launched its new Fiber™ platform, which utilizes a technology they call “micro” automated fiber placement (μAFP), that radically reduces the structure and cost of the typical AFP process .
