Calibrating Your Stratasys F Series 3D Printer for TPU Flexible Filament

EmailFacebookLinkedInTwitterShare

TPU or Thermoplastic Polyurethane is a flexible 3D printer filament available for most of the Stratasys F Series printers.  TPU is an interesting filament with a Shore hardness of 92A. 3D printing TPU is useful for making models of gaskets, seals, dampeners, and any other application where some flex is necessary. Due to the flexible nature of TPU we should keep some things in mind when calibrating our TPU-dedicated print head.  The TPU head is blue compared to the regular […]

INSTALLING YOUR STRATASYS J55 BUILD TRAY So you got yourself one of the brand new Stratasys J55 full color 3D printers. One of the many impressive features it has is the build tray size to printer footprint ratio. Today I will cover installation of the build tray into the printer. First open the printer door and locate the build tray turntable. There is a securing nut that is located in the center. Find the dedicated build tray wrench located in […]

Creating Custom Fixtures with 3D Printing

EmailFacebookLinkedInTwitterShare

Creating custom machining and assembly fixtures is often a costly and time-consuming process. Using 3D printing, custom fixtures can be created in a fraction of the time at a cost that is justifiable for short run parts and one-offs. To demonstrate this, I have this scaled model for an engine cover. This shape is highly complex and cutting this from modeling foam can be a challenge because of the materials brittle nature.  Because of the constraints of the machine I […]

As I visit customer sites, I am amazed at the stacks of empty material spools, cartridges, canisters and containers stacked up and collecting dust from 3D Printing of FDM (Fused Deposition Modeling) and/or PolyJet equipment. Some customers still do not know that Stratasys offers a recycling program for these empty material containers at no shipping cost to the customer. Stratasys will provide you a shipping label to return empty containers Start your recycling process by visiting https://www.stratasys.com/recycling. On the website, […]

Stratasys Digital Anatomy 3D Printer: Tissue Matrix Deep Dive

EmailFacebookLinkedInTwitterShare

Late last year, we announced the addition of the Digital Anatomy Printer series to our line of Polyjet machine offerings from Stratasys. We have a few great blog posts that tackle this announcement and machine capabilities, specifications, and ideal applications from a high level. Here, I’d like to take the time to focus a bit more on a topic that comes up quite a bit in the field. That is, the concept of the printed micro-structures, or morphologies, that are […]

Using Stratasys Insight’s Offset Tool to Improve 3D Printed Text

EmailFacebookLinkedInTwitterShare

Text is extremely common on manufactured parts for instructional purposes, warnings, or simply labeling purposes. Sometimes the text is painted on or placed with a sticker but very often the parts have text built into the part itself. Sometimes when you try to print a part with integral text either raised out of the part or carved into the part, FDM printers can have trouble accurately recreating the text geometry. This occurs when the path of the text is too […]

Scaling Down 3D Printing Cost

EmailFacebookLinkedInTwitterShare

3D printing prototypes are often intended to meet the requirements of Form, Fit and/or Function. But sometimes only Form is required to verify a shape and Fit or Function are not necessary. For large bulky models, the material cost can be significant as well as build time. Most people are not aware that a 50% scale reduction could save up to 800% material. Let’s investigate this idea. Building a solid cube that is 1x1x1 inches the material usage will obviously […]

Unpacking GrabCAD .Print Files

EmailFacebookLinkedInTwitterShare

GrabCAD Print does an outstanding job of repairing STL files by repairing missing triangles, overlapping triangles, stitching, etc. But one of my pet peeves is that while it will correct an STL file, it will not let you save the repaired STL file. I would like to export the repaired STL file for future use and not have to rerun the repair procedure each time I load it into GrabCAD Print. This is also true after you scale a part […]

Desktop Metal Printing Process – Printing

EmailFacebookLinkedInTwitterShare

  The Desktop Metal Printing process allows you to produce solid metal parts, in-house, in an office environment. The entire process is based off the metal injection molding process, or MIM. The MIM process involves making tooling to inject a metal powder/polymer/binder mixture into the desired shape. The parts are in a ‘green’ state and not full strength yet. Then the part is put through a debinder tank of liquid, to remove the binding agent from the metal, leaving the […]
