SOLIDWORKS 2017 What’s New: Importing and Exporting 3D Manufacturing Format (3MF) Files – #SW2017

Importing and Exporting 3D Manufacturing Format (3MF) Files   For almost 30 years STL (Surface Tessellated Language) has been the predominate format for 3D Printers. So why develop something new? 3D Printers have made significant strides in development with accuracy, resolution, materials, colors, etc., but sadly the STL file has remained stagnant. The STL format simply wraps triangles or tessellates a surface; recording the vertices of the triangles in 3-Dimensional space, it does not record any information regarding color, material, texture, etc.   When Microsoft sought to implement 3D printing support that would solve customers’ existing problems and address future needs, an important consideration was how applications should pass model

Stratasys 3D Printing: How to Setup a Multi Body Print Job – Polyjet

Setting up a Multi Body Print with a Stratasys 3D Printer – Polyjet Some of the Objet Polyjet line of Stratasys machines can print in multiple materials at the same time. You can get parts that have a hard plastic surface, clear/see through sections, and soft rubber over molding all in one print job. But how does the printer know where to apply the specific materials? The user interface in the Objet Studio software is very simple and easy to use. All you have to do is assign a specific material to an entire STL model. Let’s take a look at a pair of glasses that will need rigid material for

Load Cell Calibration on a Stratasys Polyjet Desktop Printer

The load cells measure the weight of the material bottles so the printer knows how much material is in each bottle. The printer uses this information to determine which bottles to use and when they are empty. You should calibrate the load cells once a month for a heavy usage machine or at least once every other month to make sure the load cells are reading correctly. To start the load cell calibration click on Options-Wizards-Load Cell Calibration. It is recommended that you do all 5 load cells at one time. 2 support-2 model and 1 waste When you open the load cell calibration wizard it will ask you which

X, Y, & Z Calibration for your Uprint, 1200, and Fortus 250mc Printers

On your FDM system you can run a number of different materials and/or colors through it. Over time the tips deteriorate and need replacing. Some colors such as blue and orange tend to leave trails of the material in the tip as well that can come out even after purging and will be embedded into your other color parts. For instances like this we recommend keeping spare tips for these colors so they don’t ruin a part after you do a material change. One of the most important things to do after a tip change is to make sure your brush flicker is not worn, the tip shields are good,

New Heads Filling Wizard Method

We have found that when doing a heads filling calibration there are extra steps that should be taken to ensure an accurate calibration. Manually changing the liquid level sensors back to factory values will help the machine calibrate the sensors accurately.  Do do this extra step simply enter maintenance mode then go under the Parameter Manager. Scroll down to Heads Filling. Then change the first four values to look like the values below. Then follow the normal Heads filling calibration procedure. Here is a link to heads filling Blog link- https://www.cati.com/blog/2016/06/head-filling-error-and-calibration-your-objet-desktop-can-display-an-error-related-to-heads-filling-while-it-is-printing/ Dave Murawski

CATI Supports Boy Scout STEM Camp

Computer Aided Technology, LLC participated a 3rd consecutive year in the Boy Scouts of America STEM (Science, Technology, Engineering, and Mathematics) Camp Week for the Greater St. Louis Area Council. The Boy Scouts of America created a new NOVA program which emphasizes STEM and gives Scouts an opportunity to explore these skills and be recognized for their achievements.   Judy Marlo and Mark Abshire from Computer Aided Technology, LLC were able to display the 3D Printing technology to campers at the Beaumont Scout Reservation.  A Stratasys uPrint SE+ FDM (Fused Deposition Modeling) 3D printer was set up to demonstrate the actual printing, while also displaying 3D printed parts and providing

Stratasys J750: Color Selection and Texture Mapping in Polyjet Studio

If you already own, or are currently looking at purchasing a new Stratasys J750, you are aware that Stratasys’ newest Polyjet printer is now able to print in full color due to six material bays. This great new feature allows for greater product realism and more opportunities for combining materials. Today we will be talking about how to apply custom colors and texture maps to your parts in the new Polyjet Studio. Polyjet studio has roughly the same functionality as the old Objet Studio with the addition of a new interface, and a color selection tool. We can first tell the machines which materials are loaded which will determine which

3D Printing Materials: FDM and Polyjet

Early this week I was at the CATI Product Development forum held at the NIU Rockford, IL campus. We had a great attendee turnout for this event. I conducted a presentation on materials for FDM and Polyjet and applications where there could be a crossover using either both or separate technologies. I thought I would provide some slides from this presentation along with commentary. I start my presentation by stating additive manufacturing technologies have been around for some time now and the equipment manufacturers will be focusing a lot of their R&D budget on materials for these machines. Sure, new additive manufacturing equipment will “pop up” however not at the

Polyjet and FDM Material Expiration Date and Shelf Life

Both Polyjet and FDM materials have a shelf life to them and Polyjet has a hard expiration date which it won’t read in the machine past that date. The shelf life for the material is from when it’s manufactured till when it’s no longer available. For FDM machines the shelf of the material is about 3 years from manufactured date as long as the sealed bag and cartridge is not opened. If the bag is opened the shelf life goes down to about 6 months. Material being open to the environment absorbs moisture and will cause print quality issues and shorten tip life expectancy. The manufacturing date can be found
