Justifying 3D Printing for Your Company (Part 2 of 3) – Collecting the Information

This a part 2 of a 3 part series discussing basics of justifying 3D printing equipment for your company. It is broken down into 3 basic tasks: Choosing the correct 3D Printer (click here to view previous blog) Collecting information Creating the presentation After completing Step 1 above, you should have narrowed your choice of 3D printing technologies and selected a couple of models to evaluate. Now we can begin Collecting Information for the justification process. Most people will consider […]

Choosing a 3D Printer – Why FDM (Fused Deposition Modeling)

Choosing a 3D Printer – Why FDM (Fused Deposition Modeling) Selecting a 3D printer is much like choosing your car. While the initial cost is generally your first criteria, as you explore options, features, safety, reliability, maintenance, etc. your focus often shifts from “cost” to “value”. Value often includes extra or ‘non-tangible’ benefits beyond the physical dollars. Some of the value questions you should be asking about 3D Printers are: Is the technology proven? Is the technology safe? Will the […]

Discovering your 3D Printer’s Capabilities – Part 3

This is the last of a brief series on understanding 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. In part 1 of this series, we discussed how structural supports are dependent on 3 variables; technology, material and layer thickness. We showed how some overhangs can be built in FDM without a support structure. See Discovering your […]

Stratasys 3D Printing: Discovering Your 3D Printer’s Capabilities – Part 2

Discovering Your 3D Printer’s Capabilities – Part 2 This is the 2nd 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. When 3D printing holes with FDM (Fused Deposition Modeling) it is always desirable to position the hole axis perpendicular to the platform. Unfortunately some designs (channels for wiring ,tubing, […]

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 […]

Stratasys 3D Printing: Photoelasticity with PolyJet

Photoelasticity with PolyJet   Photoelasticity is a visual method to determine the stress distribution of a part geometry.  Unlike analytical methods of stress calculations, photoelasticity gives a fairly accurate picture of stress distribution around any imperfections in the actual geometry.  This method can be an important tool for identifying critical stress concentration in irregular geometries.   The principal of photoelasticity is based on rays of light passing through certain transparent materials with two refractive indices to create a phenomenon of an isochromatic image […]

Stratasys 3D Printing: FDM Build Parameters to Create a Vacuum

FDM Build Parameters to Create a Vacuum   The 3D printing process of layering extruded material makes FDM parts porous. This is great for many applications such as Thermoforming that requires air to be drawn through a tool. But what if you want the part to hold a vacuum? To hold a vacuum the FDM part needs to be non-porous or dense. This is often achieved by sealing the part and there are several well documented procedures for sealing parts. […]

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, […]
