Vivid Materials Part 2- How should I use them?

1 5 Beginner
Our previous vivid tutorial discussed the expanded capabilities and applications of the new vivid materials. Among the things we mentioned were expanded color selection, increased control over color selection, increased automation in color proofing, brighter whites, smoother color gradients, and of course, transparency and vividness. We explained how this enables applications like rapid prototyping for transparent parts, Perspex® imitations, and transparent vividness for parts like toys and light covers. This tutorial covers the technical specs and explains how to use them to print opaque and transparent parts.

Matching Up Your Colors with the Pantone™ Color Library

1 0 Intermediate
Recently, the Stratasys J7 series began offering the Pantone™ color library on GrabCAD Print. Operators, designers, and manufacturers can now choose Pantone colors straight from GrabCAD Print. This introduces Pantone, the gold standard of color for all industries, into 3D printing and enables color-critical decisions at every stage of the workflow. The ability to use Pantone colors improves and simplifies color communication between designers, modelers, and manufacturers. For the first time in 3D printing history, you can define, communicate, and consistently produce the colors that you work with offline from the world’s most universal and established color language. You can leverage this new feature to create one-click prototypes, models with skin tones, coatings, and any other design-realism need. This improves quality and reliability of prints, cutting time and cost.

PolyJet Best Practices: How to Prototype Surfaces with Varied Friction Coefficients

0 0 Intermediate
Friction is defined as the force that opposes the relative motion or tendency of such motion of two surfaces in contact. The friction coefficient of a prototype’s surface is a functional component, not an aesthetic one, and simulates the end product’s mechanical properties. A well-designed prototype that takes friction into consideration can have the following advantages: an improved grip for the end-user, reduced part wear, simulated movement functionality and sliding abilities. PolyJetTM ConnexTM 3D Printing systems provide a solution for prototyping surfaces with varied friction coefficients that were impossible or cost-prohibitive to prototype in the past. By being able to print several materials in one build process, Connex systems can produce prototypes with varying friction areas on one given part. Users determine the friction coefficients for different areas of a part according to the load factor. This saves time and money by providing an easy solution for prototyping complex parts whose dynamic friction coefficients can be tested in a single build process.

Printing for FDM Printers

0 0 Beginner
GradCAD Print is the software developed by GrabCAD to plan and execute prints for Stratasys printers. With this tool users can print directly from CAD, plan printing jobs more efficiently, and remotely monitor a print. This tutorial is a short introduction to printing on Stratasys FDM printers.

How to Prepare a 3D Printed Composite Tool for Use

0 0 Intermediate
FDM composite tooling, similar to traditional tooling technologies, typically requires some level of post-processing depending on the size, application, and complexity of the tool. The most common post-processing operation for FDM composite tooling is sealing. The following is brought to you by Stratasys.

In our previous tutorials, we introduced the concept of proofing for full color 3D Printing, along with setting up the soft proofing workspace. Now, we will look into how to actually soft proof using some simple adjustment techniques within Adobe® Photoshop®.

3D Printing: Tip Selection FDM Best Practices

0 0 Intermediate
To minimize build time and ensure feature details are built, it is important to select the correct tip size for each part. Using too small a tip on a part can significantly increase build times. Example: a part with a 5” z-axis dimension will have 500 layers using a T16 tip, 715 layers using a T12 tip, and 1000 layers using a T10 tip. The following tutorial is brought to you by Stratasys.

[DRAFT] How to Create Better Transparent Parts

0 0 Beginner
Printing with VeroClear model material makes translucent parts both possible and practical. With a little post-processing you can control the degree of model transparency. The clarity of VeroClear parts will improve after 1-2 days in an office environment due to the exposure of white light. The following tutorial is brought to you by Stratasys.

PolyJet Multi-Materials For Impact Resistance

0 0 Intermediate
Impact resistance, or toughness, is defined by the relative susceptibility of plastics to fracture under stresses applied at high speeds. In materials science and metallurgy, impact resistance is a material’s resistance to fracture when stressed. It is defined as the amount of energy per volume that a material can absorb before rupturing. Many of today’s appliances have to endure impact due to how they are used, accidents, safety requirements, and more. The impact resistance of plastics can be improved by adding a soft material coating on top of hard plastic materials. The following is brought to you by Stratasys.

How to Media Blast FDM Parts

0 0 Intermediate
The normal surface finish of FDM parts is suitable for most purposes, but in applications where a different finish is required, media blasting is an inexpensive and quick solution. Following the best practices helps reduce the risk of damaging or breaking a part when media blasting. The following is brought to you by Stratasys.

How to Apply Custom Toolpaths for Thin Walls and Bosses

0 0 Intermediate
When processing an STL file, smaller or larger toolpath widths are sometimes required to achieve proper fill for certain portions or features of a part. While changing the tip or modifying global toolpath settings for the entire part will generally work, oftentimes it is unnecessary. Custom Groups provide a means to specify different toolpath parameters for an individual curve or curves. The following tutorial is brought to you by Stratasys:

How to Section Oversized Parts Using Insight

0 0 Intermediate
A part that is larger than the build envelope of a 3D printer can still be printed. Oversized parts may be sectioned and subsequently bonded. This tutorial will give you the best practices for sectioning oversized parts. Software: Insight software

Curl Management Using Insight

0 0 Intermediate
Curl is defined as the distortion of horizontal surfaces caused by the shrinkage of a new layer as it’s applied over the existing layers, causing those layers to deform. This can be a challenge with parts that have thick cross sections or large at areas. InsightTM software features several tools that can mitigate part curl even on the most challenging geometries.

How to Create Variable Density FDM 3D Printed Parts

0 0 Beginner
A unique characteristic of FDM technology is that a single part can have regions with different build styles, which can be used to make a part with variable densities. With just a few minutes of extra design and pre-processing, you can save hours of build time and/or dramatically improve the part’s properties.

Inserting Hardware Post-Build

0 0 Intermediate
Various types of hardware are commonly used in plastic parts to withstand the torque and load applied when joining parts to create assemblies. Like machined or molded plastics parts, components made with FDM technology can also have hardware inserted into them. Inserts may be added during an FDM build or in a secondary, post-build operation. This Best Practice covers secondary insertion of hardware with common methods such as adhesive bonding, pressing, and heat setting.
