STL Output Settings for CAD

Friday, May 15th, 2015

Last fall I switched responsibilities here at 3DVision.  I moved from the SOLIDWORKS side of our business to 3D Printing.  Some of our readers may recall chatting with me on Technical Support or sitting in one of my training classes.  For my first “official” blog post I thought it might be good to mix both worlds – CAD and 3D Printing.

CAD comes into play when we think about what we need to print.  Currently, the industry standard file format for 3D Printing is the STL (Standard Tessellation Language) file.  All major CAD packages can save or export in the STL format, including SOLIDWORKS.  Simply click File-Save As-STL.  Once the STL file type has been selected you’ll notice an options button appears.  Clicking this options button shows you all the settings we can change regarding the STL File itself.

Quick Tips when setting up your STL Output

1.  Use the Binary option to save disk space, it reduces the file size by a ratio of 6:1.

2.  The STL itself is unitless.  SOLIDWORKS will output in the specified units, no matter what unit we use in our model.  When we bring the model into our 3D Printing software, we’ll need to specify the units used.  If the parts come in really big or small, the software will ask you to confirm.

3.  Stratasys recommends a Deviation tolerance of .001″-.012″ [.03mm-.3mm] I generally set the resolution to Custom and use .0005″ which is a touch smaller than they recommend. The files tend to grow very fast when you get down much smaller than that.  The bigger the file the longer it takes to process in the 3D Printer software.  [I have a model from a customer that was 750mb and took 30 hours to process.  We need to strike a balance between getting a high tolerance part and keeping file size/processing time down.]

4.  Stratasys recommends an angle tolerance of 5-10°.  The default in SOLIDWORKS is 10° so I leave this alone.

 

Below is a small example explaining the Deviation (chordal tolerance) and the Angular tolerance.  This is the max difference allowed between the faceted surface and the SOLIDWORKS Model.

We can’t print a model better than the STL, so it is always good to check the options before saving the model, and verify the STL looks good before processing.

Introducing the new Objet1000 Plus

the World’s Largest Mult-Material 3D Printer

objet1000 Plus

Create Large or Small Production Tools and Full-Scale Prototypes

Maximize your productivity and quickly achieve ROI with the Objet1000 Plus 3D Production System. Its multi-material capabilities, substantial throughput and ultra-large build tray get your jobs done faster, smarter and with more precision. Based on PolyJet™ technology, this versatile system enables engineers, manufacturers, designers and universities to 3D print any design, no matter how complex or detailed.

Part size is also no object: The Objet1000 Plus is equally adept at printing large or small prototypes with no compromise on precision. Print large parts over 1 meter in length in one build, eliminating the need to split your largest files in CAD and later bond the parts. Print many parts in one job and enjoy a competitively low cost per part.

Multi-Material Versatility

Along with its size, the Objet1000 Plus offers impressive multi-material 3D printing capabilities with the power of Digital Materials. Build parts with diverse material properties in one job, and even combine as many as 14 materials in one part.

High ThroughPut, Low Cost of Ownership

With an ultra-large build tray measuing 1000 x 800 x 500mm (39.3 x 31.4 x 19.6 in.), the versatile Objet1000 Plus amplifies productivity without sacrificing accuracy. It works largely unattended to produce multi-material parts directly from CAD data, preserving fine details and geometric complexity at any scale.

3D Printing Webinar – Printed Prototypes Feature Overmolded Parts

Wednesday, May 15th, 2013

Any engineer working with CAD/CAM software knows the value of having a physical model in hand. Now, thanks to advanced 3D printing technology, engineers can create prototype models featuring overmodeled or soft touch parts, all in one procedure.

Additive manufacturing technology has advanced so far that 3D printed prototypes are not only used for design validation but also for testing form, fit and function. Now, thanks to advanced 3D printing technology, engineers can create prototype models featuring overmodeled or soft touch parts, all in one procedure.

Traditionally, an overmold or soft touch part – as commonly found on power tools, consumer electronics and medical devices – takes days to create and produce. With PolyJet Connex technology, these parts can be made simultaneously, saving time and money.

With PolyJet Connex technology, resolution is high and multiple flexibilities or durometers are possible.

You are personally invited to join Stratasys and PolyJet expert, Randy Stevens, for a presentation devoted to multi-material 3D printing solutions for enhanced prototype development.

Who Should Attend:
– Engineering Managers and Directors
– Design Engineers
– Product Designers
– Manufacturing Engineers
– Plant Managers and Directors

When: May 23, 2013 @ 2PM EDT
