3D Printer Threads and Thread Inserts for Plastic

At Formlabs, we design various functional parts for printing on our stereolithographic (SLA) 3D printers such as the Form 3. These parts include prototypes used for our own R&D, clamps and fasteners to be used on our production lines, models to check the design before casting the final product in the appropriate material, such as nylon.

Regardless of the application, we often need to connect 3D printed components with screws and threaded fasteners. As the catalog of versatile and reliable engineering polymers grows, the differences between "imitation" prototypes and functional prototypes diminish.

This article is a guide to threading and threading 3D parts with a 3D printer. There are many ways to connect multiple 3D printed parts together, but if you need the ability to repeatedly connect and disconnect components and secure mechanical fastening, there is no real substitute for metal screws.

Do you like to see everything with your own eyes? Watch a video about 3D printing threaded connections and threaded inserts for 3D plastic parts.

Let's take a look at some of the threading options for 3D parts we've put together based on years of Formlabs experience and your suggestions. We've ranked these options, starting with the one we think is the best, with the pros and cons of each option for different use cases.

Benefits: Strongly connects 3D printed parts without the use of glue. The metal threads are durable and reusable.

Drawbacks: Inserts may loosen as temperature rises.

3D print a sleeve blank with a depth and diameter that matches the insert specifications. Rinse with isopropyl alcohol (IPA) and allow to dry without final polymerization. Insert the insert into the sleeve with a screwdriver and use the screw to secure it completely into the plastic. Then finish curing the part to reduce the creep effect and fix the insert in the plastic even better. Performing this step last reduces the chance that the insert will break the sleeve when screwed in.

Benefits: Connects 3D printed parts very securely. The metal threads are durable and reusable.

Cons: Adhesive required (don't try to use a soldering iron!).

Threaded inserts with heat setting are designed for installation in thermoplastics using a soldering iron with a soldering tip. They can be used in acrylic models and Fused Deposition Models (FDM), but cannot be installed in SLA photopolymer parts, which bend but do not melt when heated.

Check out our detailed guide comparing FDM vs. SLA 3D printers to see how they differ in terms of print quality, materials, application, workflow, speed, cost, and more.

However, the notches and ridges on the heat set inserts make them a very effective thread fastener if you bond them with a two part epoxy or cyanoacrylate adhesive. Determine the bushing size by the largest diameter of the insert and apply some adhesive before installation. For best results, the part must be completely dry and cured.

Benefits: Nuts are easy to match to any required screw size.

Drawbacks: Side nut slots can eliminate the need for glue, but can make it harder to support the model during printing.

Adding a hexagon socket to the nut press-fit end creates a reusable strong metal-to-metal connection. To increase the twisting force, you can choose a square nut. This nut can also be plastic or have blocking elements. If necessary, a drop of cyanoacrylate glue will help hold the nut in place, but if the design includes a side socket, there is no need for glue. Use a 0.1 mm offset around the press-in nut and clearance around the screw itself.

Benefits: Prototyping uses the same metal products as mass-produced injection molded parts. Sleeve blanks made from Tough (and Durable) polymer are unlikely to crack if you follow the screw manufacturer's sleeve design guidelines.

Disadvantages: The screws will hold tight, but the threads will not be as resistant to repeated use as metal threads. Standard resins can be used, but the bushing is more likely to crack.

Follow manufacturer's recommendations for core sizes and print with high impact engineering resins (such as our Tough Resin and Durable Resin). Before using the screws, complete the final curing. If you are prototyping an injection molded part that will use tapping or tapping screws in its final assembly, this is a good option for testing.

Benefits: No need to buy special plastic screws.

Disadvantages: The screws will hold tight, but the threads will not be as resistant to repeated use as metal threads.

We have tested screws in our Tough Resin product and found that their use is identical to that of threading screws designed for plastics. The size of the hole diameter of the threaded bushing must be in the range between the main (threaded) diameter of the screw and the inner diameter. The screw shown is a #8 screw in a 0.16" diameter hole.

Benefits: Can be used for prototyping large and custom threaded designs.

Disadvantages: Not a durable or reusable fastening solution, especially for smaller thread sizes.

3D printed threads from standard resins are better than Tough Resins because they are much harder. 3D printed threads remain relatively brittle, depending on the size of the thread, and are not recommended if the fastening system is to be used continuously and repeatedly.

Thread sizes ¼-20 or larger are generally functional without the need for post-processing. For smaller screws, the threads must be modified to provide better fastening. For example, printing a round thread profile (on a screw and a nut) and using a 0.1mm offset results in a better thread fit and improved wear characteristics. For all screw sizes, it is best to orient the parts so that the supporting structures do not touch the threads.

White Paper

Tolerance and fit design reduces post-processing time and simplifies assembly, as well as reduces material costs per iteration.

Lead screw

FAQ

Lead screws are an excellent replacement for

threaded rods

From RepRap Wiki: Threaded Rod

Lead screws are threaded rods used to enter a component, such as an X-axis assembly to a Z-axis. For most repraping, a regular (straight!) threaded rod is sufficient, but for higher accuracy and reduced wobble, you can use real lead screws.

There are two main thread profiles for lead screws, both of which are trapezoidal: trapezoidal and Acme. An important but subtle difference is the angle of the thread flange. Be sure to buy the right nuts.

See also Wikipedia: Lead screw:

A lead screw (or lead screw), also known as a power screw1 or lead screw2, is a screw used as a lever in a machine to convert rotational motion into linear motion. Due to the large area of ​​sliding contact between their female and female elements, screw threads have a high frictional energy loss compared to other connections. They are not typically used for high power transmission, but rather for intermittent use in low power actuators and positioners. Common applications are linear drives, mechanical slides (eg in machine tools), vices, presses and jacks. 3

Lead screws are made in the same way as other thread forms (they can be rolled, cut or sharpened).

There are three types of thread used with lead screws:

  • Area
  • Buttress
  • Akme

Advantages and disadvantages:

The advantages of lead screw are as follows:

  • Heavy duty
    • Compact
    • Easy to design
    • Easy to manufacture; no special equipment required
    • Great mechanical advantage
    • Precise and accurate linear motion
    • Smooth, quiet and low maintenance
    • Minimum number of parts
    • Most are self-locking

The disadvantage is that most of them are not very effective. Due to their low efficiency, they cannot be used in continuous power transmission systems. They also have a high degree of friction on the filament, which can wear out the filaments quickly. For square threads, the nut must be replaced; for trapezoidal threads, a split nut can be used to compensate for wear.
