How to 3D Print in Full Color (Part 1)

20 3 Beginner
This is a series of tutorials to help printer operators who are NOT graphic artists get the absolute most out of their multi-color, multi-material 3D printers, like the Stratasys J750. We will cover what types of files multi-color printers can accept and how to manipulate colors in Photoshop, Rhino, etc, to get the full gradient texture effects that most color printer users want.

Finishing Options for FDM and PolyJet 3D Printed Parts

16 0 Beginner
Finishing or secondary operations encompasses a broad range of processes that change a manufactured part’s properties. Engineers can employ finishing simply to improve part’s appearance and reshape it to meet certain dimensions, or use it to enhance functionality, such as increasing strength, chemical resistance, electrical conductivity and more. Secondary operations basically turn raw parts into finished goods and this isn’t limited to traditional manufactured parts. 3D printed parts can also be enhanced with secondary operations, but much like designing for additive manufacturing, different processes and best practices apply. Throughout the product design and manufacturing process, engineers should also be thinking about how 3D printed parts can be finished. Determining the appropriate finishing operations depends on the additive process, material and geometry as well as the desired aesthetics and functionality. This guide explains the primary finishing operations additive manufacturing service providers implement for FDM and PolyJet 3D printing technologies, grouped by possible finishing objectives, and compatible materials and applicable design considerations.

How to 3D Print in Full Color (Part 3): Clear + Texture Together

16 0 Expert
This is the third in a series of tutorials to help printer operators who are NOT graphic artists get the absolute most out of their multi-color, multi-material 3D printers, like the Stratasys J750. We will cover how to create models with semi-transparent textures wrapped around curved, transparent bodies (taking advantage of a new slicer from Stratasys), and how to fix UV-mapping problems when wrapping 2D textures around 3D bodies goes wrong.

PolyJet Materials and Uses: Tips and Tricks

7 3 Intermediate
Materials are critical to prototyping and production success. At the heart of any great application is the right material: one that performs as needed under the application’s conditions. This is just as true for 3D printing as it has always been for molding, machining, and casting. While the 3D printing industry has a wide variety of materials to choose from, ranging from plastic to metal and wax to paper, the selection is often quite limited for a given technology. It is even more restricted for specific 3D printers, with one exception.

Hand Sanding and Polishing for PolyJet 3D Printed Parts

7 1 Intermediate
This tutorial demonstrates how to handle post-processing for printed parts when using the Stratasys J750. The Stratasys J750 offers appearance capabilities that are relatively advanced in the world of 3D printing. To fully realize the appearance of a printed part or mimic an injection molded part, sanding and polishing by hand is recommended. Featured in the picture is a stick shift with a combination of a few colors and surface appearances, all achieved in one print: wood grain texture, simulated leather over-wrap, with stitched binding, A mock color LCD screen featuring a VeroClear screen surface. Here's how to polish only the LCD screen and wood grain to produce a more realistic finish – without the need for a lacquer application.

Using PolyJet 3D Printing Technology for Shock Absorption

5 0 Beginner
Shock and energy-absorbing components are often used as a safety measure to dissipate runaway energy in case of a component or system failure. Practical examples of shock absorbing components include bumpers, isolators, fasteners, mounts, spacers and pads.

Vibratory Finishing for Rigid PolyJet Parts

1 0 Beginner
Polishing PolyJetTM 3D Printed parts in a vibratory finishing system (also known as a tumbler) improves their surface finish by removing minor surface irregularities and sharp edges. With this process you can save time and manual labor, especially when dealing with large quantities or complex models. A tumbler system can polish multiple parts, hands-free, in only a few hours, depending on the size of the parts and the tumbler. This method is usually performed on metal parts, but it was tested on PolyJet models from the Digital ABSTM and VeroTM material families and found suitable.

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.

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.
