IMPROVING PRINT ACCURACY: AN OVERVIEW OF USEFUL SUPPORT STRUCTURES FOR 3D PRINTING JEWELRY

Support structures need to be carefully examined while making 3D-printed jewelry in order to achieve the best print accuracy. The jewelry business has completely changed as a result of 3D printing, which gives designers unmatched flexibility and accuracy when producing elaborate and personalized items.  These structures are essential to the success of printing, the avoidance of malformations, and the preservation of the overall quality of the outcome.

Almost all 3D printing techniques utilize support structures to ensure that an object can be printed. Supports can be used to keep pieces from deforming, fasten them to the printing bed, and make sure that parts are joined to the printed part's main body.

WHAT IS SUPPORT STRUCTURES?

One of the most important precautions for effectively manufacturing 3D printing in SLA, DLP, and LCD is the requirement for Support Structures. The purpose of support structures is to prevent deformation and crumbling. Efficient support structure implementation is critical in jewelry design, where delicate features and complex designs are common. Ignoring this can lead to errors in printing, distorted features, and a general lack of accuracy in the finished product. There are two typical kinds of supports: tree-like and lattice-like supports.

Lattice Support:

Often called linear support, this is the most widely used type in 3D printing. This kind of 3D printed material can sustain almost any kind of overhang or bridge. They are more likely to harm the model's surface and be far more difficult to remove.

Tree-like Support:

Tree-like support is a structure that resembles a tree and holds up the model's overhangs. A benefit of employing 3D printed support shaped like a tree is that it is less damaging to the underside of the overhang and is simpler to discard. However, it is appropriate for non-flat overhangs only. For flat overhangs, it does not offer sufficient support.

CRUCIAL STEPS FOR EFFECTIVE SUPPORT STRUCTURES:

·         Geometry Analysis:

Before beginning a 3D print, the geometry of the design should be carefully examined to create the exact position and type of support structure.

·         Customization of Support Settings:

Density, pattern, and interface layers are just a few of the support settings that may be customized using modern slicing tools. It improves the print's overall accuracy.

·         Orientation Is Important:

During printing, the jewelry piece's orientation determines how well support structures work. Various orientations can aid in minimizing material waste and post-processing efforts.

·         Material Parameters:

The kind of material utilized in 3D printing has a significant impact on how well support structures function. Trying out several material combinations might help determine the best fit for a particular jewelry project.

·         Layer Height and Resolution:

Support structures can be used to modify the layer height and resolution of the 3D printer, ensuring accurate capture of complex details.

ASPECTS TO TAKE INTO ACCOUNT WHEN SELECTING SUPPORT STRUCTURES:

Various materials behave differently during printing. To avoid issues like adhesion issues or damage to the final print, choosing support materials that are appropriate for the primary material is crucial. The support structures should be designed such that they may be easily taken out without causing harm to the jewelry piece's fragile parts. Think about utilizing soluble or easily separated materials. It is necessary to be able to modify support structures to the unique specifications of the design. 

WHEN DO YOU REQUIRE SUPPORT STRUCTURES?

·         In 3D printing, support structures are necessary. For models with unsettling overhangs or bridges, they are very necessary. Therefore, choosing the appropriate supports is essential when producing complex models with 3D printing.

· To 3D print a model with an overhang or a bridge that has nothing underneath it, support may be required. Several illustrations of overhangs and bridges featuring the letters Y, H, and T.

·         Not every overhang requires support. As a general guideline, you might be able to print an overhang without needing support if it tilts at an angle less than 45 degrees from the vertical.

·         Not all bridges require support just as overhangs. In this case, a bridge under 10 mm in length might be able to be printed by the printer without the need for support.

·         Examine the surface quality and dimensional accuracy of the final pieces. Determine the angle at which the printer begins to malfunction. At the selected settings, this is the maximum overhang angle or bridging distance that your printer can print without assistance.

THE DRAWBACK OF SUPPORT:

Support structures are necessary, however, they will increase the total production process's printing time and material costs.

Material Expenditures:

During the printing process, support structures will need more material, which will increase the time and expense of materials. It's also important to keep in mind that supports are usually discarded rather than reused, causing it to be a wasting material.

Limited Geometric Liberty:

To make manual support removal easier, hand or tool access needs to be considered while constructing supports. But this can keep you from designing certain geometries that require support structures and are inaccessible with a hand or tool.

Extra Time:

Designing a section that fits support structures and building the supports themselves takes more time. Support structures for industrial applications still require some manual touchup and a certain level of design skill, even with software that offers automatic support production.

Post-Processing:

When supports need to be physically removed, the post-processing time will increase as well.

Hazard of Damage:

If supports are incorrectly positioned—for example, on delicate features—they may break off with the support structure, seriously damaging the section.

Possibility of Model Destruction:

Support structures often come into contact with the downward-facing faces of the models, which raises the possibility of model damage. Supporting overhangs and bridges can only be accomplished in this manner. They may leave imperfections on the model surface if you are not careful when removing them. In the worst scenario, a portion of the model and the support structure might separate.
