Stratasys 3D Printing: Part Shift on FDM machines

Part Shift on FDM machines   Part shift is one type of part quality issue we see on FDM machines. There are several simple things that can be checked that may resolve the issue.     Here we see some examples of parts shifting.   The first and most simple thing to check is to  make sure the build plate is latched and secured.  If you have a Dimension 1200, Fortus or Uprint, check to see that the print head will toggle from side to side with only minimal resistance.   Next, check all the rods and belts in the build chamber to make sure they are not loose.   With the machine off, move the head around and

SOLIDWORKS: Nonlinear Material Models in SOLIDWORKS Simulation

Nonlinear Material Models in SOLIDWORKS Simulation   If you are using SOLIDWORKS Simulation Premium, you have access to the Nonlinear study type. One of the advantages of this study type over the Linear Static study is the ability to apply loads and boundary conditions that vary over time. Another is the access to multiple material models that represent nonlinear material behaviors:   Nonlinear Elastic Hyper-elastic Elasto-plastic Super Elastic Nitinol Linear Visco-elastic Creep   Let me give you a brief description of each.   Nonlinear Elastic Model   For those materials that don’t exhibit any linear behavior, e.g., a stress-strain relationship like the graph below, the nonlinear elastic material model is

Stratasys 3D Printing: Introducing the NEW Stratasys F123 Series 3D Printers

Introducing the NEW Stratasys F123 Series 3D Printers   The Stratasys F123 Series 3D Printers make rapid prototyping more efficient and productive. These 3D printers were designed to remove the barriers designers and engineers face by making the RP process more efficient and productive. The Stratasys F123 Series addresses typical rapid prototyping pain points and lets companies create better products faster, reducing the time to market.     The hallmark of the Stratasys F123 3D Printer Series is that it is designed to meet the needs of the total RP process: concept verification, design validation and functional testing. And it will do this with economy and speed in a workgroup

SOLIDWORKS: Macros Redux For the SOLIDWORKS Electrical Schematic Project

Format Image

Macros Redux For the SOLIDWORKS Electrical Schematic Project   Several years past, I took a look at macro functions within the SOLIDWORKS Schematic tool.  Macros are a predefined section of symbols and circuits that speed up our design with reuse of existing work. The advantage being that instead of having to open an existing project and copy – paste, users can simply place a macro on any project from the library panel and place on a page.   A new addition to the software in recent years is the Project Macro. Project macros fill in the gap where regular scheme macros fall short. A project macro can be made up

Stratasys 3D Printing: Objet Pattern Test

Objet Pattern Test   The Polyjet rapid prototyping machines are Stratasys’ highest accuracy and highest detail machines. To keep the accuracy and reliability of these machines so high, we will have to do some preventative maintenance checks and calibrations on them occasionally. One of these tests is the ‘pattern test.’   The pattern test is quick, less than 5 minutes, preventative maintenance check that is recommended to be performed about once a week, or before a really large build. The point of the pattern test is to gather information about the health of your print heads. We want to make sure that they are still in good working condition and

SOLIDWORKS 2017: Making a Decal Transparent

Making a Decal Transparent   This blog article will walk you through how to make your Decals transparent.   We start by placing our decal on our part model.   Below is an image of the property manager and decal placement (prior to making any changes).   In the property manager, you will see a section called “Mask Image”.   In this section, there are four mask options; No mask, Image mask file, Selective color mask, and Use decal image alpha channel.   The default setting is No mask, however for our transparency we will want to select the option “Selective color mask”. As shown in the image below.

How Does SOLIDWORKS Save Files?   Have you ever wondered how SOLIDWORKS saves files?   Understanding how SOLIDWORKS files relate to one another is key to file management. The SOLIDWORKS file structure is a single point database. This structure means that each piece of information is stored in only one file. If any other file needs a piece of information, it must reference the file where the information is stored rather than copy the information into itself. In SOLIDWORKS, every time a file is used in a subsequent file, it creates a “File Reference”. File References are the links to where the file information is stored.   The huge advantage

SOLIDWORKS: Make Independent Context References

Make Independent Context References   In my previous blog article, I wrote about Assembly Propagation and how it gave us some in context references. Though this automatic update is fine for our initial designs, some customers need to break these references for release and production.   Here’s the link to my previous article >>   In our bracket part, we made a hole. That hole is connected to our assembly and now we need to delete the in-context reference.         By Right-Clicking on Cut-Extrude2-> we get the option to “Make Independent”         This Breaks the references, and the feature is now editable at the

Creaform Scanning: Koenigsegg Partners with Creaform

Koenigsegg Partners with Creaform to Certify the Quality Standards of its Hypercar Lineup         Koenigsegg hypercars have received a lot of attention lately with the APEX: The Story of the Hypercar (currently available on Netflix). You may also have seen in your newsfeed for the past few weeks Top Gear’s World Exclusive Drive of the Koenigsegg Regera. Koenigsegg is also fresh out of Monterey Car Week and Pebble Beach Concours d’Elegance. With Ferrari, McLaren, Porsche and Bugatti also in the market, one thing is for sure: Koenigsegg is certainly carving an enviable reputation for itself!     Already integrating 3D printing and 3D scanning in the development

Stratasys 3D Printing: Discovering Your 3D Printer’s Capabilities – Part 1

Discovering Your 3D Printer’s Capabilities – Part 1   This is the first of a series on ideas to understand the capabilities and limitations of your 3D Printer.  When you know what your machine can achieve it can be applied to significantly aid your part design as well as throughput and quality.   Regardless of the 3D printer you are using, it is drawing a 2D image in multiple layers to create the 3rd dimension.  With this in mind, most printers will require some kind of support or brace to prevent overhanging layers on top of a previous layer from collapsing.  Some machines, typically powder based machines, will use the unused material
