If you want to learn how to add finishing touches to your products post-production before shipping to your customers or transform your own 3D printed designs to a more vivacious color you can do so by following a few simple steps. In this tutorial, Steven and Jeremy Gonzalez of The Super Maker Bros demonstrate how to paint eyeglass frames printed in Multi Jet Fusion Plastic PA12 in multiple colors, a process that can be applied to many other projects of the same 3D printed material.

Here is what you will need:

•       3D model printed in Multi Jet Fusion Plastic PA12 (also applicable for Versatile Plastic)
•       220 grit, 400 grit and 600 grit sandpaper
•       Spray paint primer
•       Spray paint in your desired color(s)
•       Clear coat matte or gloss spray paint
•       Reusable drop cloths or newspaper to protect your work area from paint
•       Highly Recommended: A respirator with replaceable filters will not only protect you from spray paint fumes but will last you through many more future paint projects.

Once you have these materials you are ready to get started. Follow the steps below and check out this video to see each step in action. 

Step 1:

Prepare your workspace by placing newspaper or a drop cloth over the area to cover any furniture or floor space in range of your spray painting pattern. Protect enough space to spray from different angles.

Step 2:

Put on your respirator. Spray paint fumes are toxic and sanding generates dust particles that are dangerous to inhale, so make sure you sand and spray in a well ventilated area and wear your respirator.

Step 3:

3D printed eyeglass frames, sanded (Photo by The Super Maker Bros)

Start by sanding the glasses pieces to smooth out their surfaces. This will also help the paint adhere to the plastic. Makerbro Tip: The best sandpaper to use is wet/dry or waterproof paper because getting the paper wet helps cool the plastic while sanding as well as keeps small dislodged plastic particles under control. Waterproof sandpaper is black instead of tan or beige.

Begin with a rougher, 220 grit sandpaper to remove any bulky texture and then move on to 400 grit and 600 grit to buff the surface smooth. The lower the number, the rougher the paper is. Be sure to rinse and dry the pieces to remove loose particles.

Makerbro Tip: To give your sandpaper more longevity, apply spray adhesive to the back of your quarter sandpaper sheet and fold it over to make an extra thick one-eighth sheet. This will give you the ability to use more pressure without tearing a hole in the paper.

Step 4:

Prime the frames using a spray primer like the Dupli color filler primer. Spray the glasses using a sweeping motion, keeping the spray can at a distance of about 6 to 12 inches. Spraying too closely will coat the object in too much paint and cause dripping or even cause the coat to crack when dry. Make sure all visible surface area is covered and let the pieces dry before spraying the other side.

Makerbro Tip: Spray paint takes about 30 minutes to dry to touch but wait between 1 to 2 hours to handle it. It will be fully dry after 24 hours.

Step 5:

Once the glasses are primed, sand the surfaces once more using the 600 grit paper to achieve maximum smoothness and wipe away any resulting dust.

Step 6:

Using the same spray painting method as with the primer, spray each piece in the color of your choice and let fully dry for 24 hours.

Makerbro Tip: Want to use more than one color on the same piece? Use masking tape to cover parts of your project you want in a different color. Once the first color dries, cover that portion and paint the rest.

Step 7:

Once the glasses have had 24 hours to fully dry, it’s time to seal up the paint with a topcoat. Using the same spray painting method, apply two layers of topcoat, leaving 1 to 2 hours of drying time in between. This helps protect the paint and enhances the shine or matte finish desired. It also gives a buffer between paint and skin contact.

Step 8:

Now assemble the pieces and you’ve got a brand new pair of glasses! You can have a pair in every color.

Experimenting with virtual reality is an exciting — and somewhat unnerving — process. It often requires much trial and error, which is precisely why the team at Spaces needed to find a final stage prototyping process to aid them. That’s where Shapeways stepped in. Spaces loves Shapeways’ dimensional accuracy and durability and has used 3D printing –primarily the Multi Jet Fusion Plastic PA12 material – ever since first discovering the company.

Why is it beneficial to print with Shapeways over traditional manufacturing methods such as injection molding?

Spaces: We are constantly inventing and iterating, most of the time under very tight time constraints. Using 3D printing allowed us to make parts that broke some rules and to make changes to parts quickly. Shapeways helped us create parts that could not be manufactured through conventional injection molding. Undercuts are a major concern with any tooling for injection molding and create a lot of work to get parts made.

Which is your most used material?

Our most used material is the Multi Jet Fusion Plastic PA12 because it gives us acceptable resolution and is durable.

Why do you print with Shapeways versus desktop 3D printing?

The quality and quantity of the Shapeways parts we print are the main benefit. For the most part, desktop printing does not produce the same quality and resolution. Also, most desktop printers can be unreliable, which is something we cannot take a chance with when printing large quantities of parts for our installations. Most of our parts are conceived using desktop printing methods and then turned over to Shapeways for printing en masse.

What are the added benefits of using Shapeways?

We have been impressed with the customer service. Personal attention is very important when we are working against tight deadlines.

The history of nylon plastics is long, especially for traditional manufacturing. Polyamides like nylon offer a high melting point and are extremely popular because of their high ductility–allowing manufacturers to engineer flexible parts for thinner structures, but more rigid pieces with thicker parts. 

Understanding Nylon 12 3D Printing Plastic

Nylon 12 serves as an exemplary model of a polyamide used for conventional methods like Injection Molding, but is also at the forefront of many applications for 3D printing plastic. In the same family as other popular Nylon materials (notably Nylon 6, Nylon 6,6, and Nylon 11), Nylon 12 is revered due to its unique suite of properties and reinforced formulations. 

Popular for its mechanical properties, tensile strength, durability, abrasion resistance, biocompatibility, and overall suitability for making functional parts, Nylon 12 has a relatively low concentration of amides and relatively low moisture absorption. These qualities may make the material trickier for 3D printing plastic, but they also imbue Nylon 12 with desirable qualities like chemical and abrasion resistance, strength, and durability. Further, Nylon 12 offers a low coefficient of friction. All of these qualities create a versatile material favored for 3D printed prototypes and end-use, functional parts featuring gears or hinges.

3D Printing Nylon 12 with Selective Laser Sintering and PA12 Material with Multi Jet Fusion

Shapeways 3D prints materials like Nylon 11 [PA11 (SLS)] and Nylon 12 [Versatile Plastic] via Selective Laser Sintering (SLS). Developed as one of the first 3D printing technologies, SLS is one of the most powerful rapid prototyping tools across all industries. Manufacturers rely on 3D printed nylon plastics for functional, end-use products in applications like aerospace and drones, and automotive. Using intensive lasers that melt nylon powder fast and evenly, SLS technology is advantageous for industrial manufacturers seeking accurate, high-performing parts that are strong and isotropic. Users are not saddled with sacrificing mechanical properties, as SLS parts are excellent in both tensile strength and modulus.

MJF is a 3D printing process developed from HP’s long-standing expertise in inkjet technologies. Droplets of fusing and detailing agents are applied along with thermal energy on top of the powdered material to define the part’s geometry. The precision of inkjet technology is such that builds can be controlled at the 3D voxel level. Shapeways uses MJF technology to 3D print the following PA 12 material: Nylon 12 Full Color (MJF), Multi Jet Fusion PA12 (MFJ PA12), and Nylon 12 Glass Beads [MJF Plastic PA12GB].

Both SLS 3D printing and MJF 3D printing offer clear advantages to any designer or engineer due to the expanded and outstanding freedom in design. This is accentuated by the ability to avoid the use of supports as surrounding and lingering powder bolsters 3D prints in p-ogress, streamlining the design process and eliminating myriad headaches. Both SLS and MJF 3D printing technologies allow for smart packing, resulting in hundreds or even thousands of parts ‘nested’ together in one build. Sustainability also plays an important role as the extra powder can be re-used in consequent builds. This is possible when reused materials are mixed at a minimum of 50/50 with virgin 3D printing powder.

Print time is relatively comparable for both processes as SLS and MJF technology can accommodate larger parts. The biggest differences lie in the precise mechanical properties of chosen 3D printing materials, finishing options, and desired timing. Find out more specifics of each 3D printing plastic below:

Nylon 11 [PA11 (SLS)] 

Nylon 11 [PA11 (SLS)] is the most flexible 3D printing nylon material due to its high elongation at break. It has slightly higher strength than the other materials. This combination of high strength and good elongation at break makes Nylon 11 [PA11 (SLS)] the most impact-resistant of 3D printing plastic material available from Shapeways in nylon. 

This material is biocompatible and known for its ductility, allowing for both durability and flexibility. Nylon 11 [PA11 (SLS)] has higher temperature resistance and is based on renewable resources, making it more environmentally friendly.

It doesn’t matter whether you’re experimenting with prototypes or printing final products. Wherever you are in the 3D design process, Versatile Plastic can be used to help you create the perfect end product.

The Many Benefits of Versatile Plastic

Versatile Plastic is ultra thin, incredibly flexible and can be used well for parts like hinges and springs. Printed on EOS P770, P396, and P110 machines through Selective Laser Sintering (SLS), when printed in a thick form, it can be strong enough to be used as structural components. Versatile Plastic is also heatproof to 175C/350F, skin-friendly and dishwasher safe.

Clearly, these features of the material provide a multitude of possibilities, and that’s precisely why Voytek Medical — a company focused on creating and developing products that lock all patient cables to a desired bedside monitor or roll stand without voiding warranties or modifying equipment — has utilized it so vastly.

“Voytek Medical has been using Shapeways in every stage of production, from concept to prototype and end-user products,” the company explained. Their job is difficult for many reasons, especially because the products they create need to be able to withstand different chemicals that they come in contact with in a hospital setting. To create their desired products, the company has been using Versatile Plastic and has seen great results from doing so. Before coming to Shapeways and using Versatile Plastic, however, there was a long trial-and-error process.

“In the trial-and-error phase of our designing, the use of extrusion desktop 3D printing in ABS was the best option available to us at the time. This material was far from precise, very brittle, and the layers tended to separate over time. From that point, stereolithography was used that brought us into the world of really designing with a purpose and good quality. The resin was brittle and dust and other mirror issues made consistent prints impossible to mass manufacture.”

Experimenting with Shapeways’ Materials

However, when they discovered Shapeways and began experimenting with the possibilities here, everything changed. For starters, they were able to continue to try out new products at an affordable cost, which allowed them to “grow and thrive at a comfortable and manageable pace.” Soon after, they discovered Versatile Plastic and its many benefits.

“In our testing, hospital cleaning chemicals had no effect on the finish or hardness of the Versatile Plastic. These chemicals are known to destroy some plastic surfaces by making them more brittle, etching and fogging on clear membranes of other equipment. In destruction testing, the material withstood all tools available to hospital staff on a regular basis.”

Finding Undeniable Success with Versatile Plastic

Now, after trying out the product for quite some time, Voytek Medical uses this material and Shapeways exclusively to print their products.
