What are the best materials and methods for post-processing LOM parts?

1 Sanding and trimming

One of the most common post-processing methods for LOM parts is sanding and trimming. This involves removing the excess material around the edges of the part, as well as smoothing out any rough or uneven surfaces. Sanding and trimming can improve the dimensional accuracy, aesthetics, and fit of LOM parts, especially for complex or curved shapes. You can use various tools and abrasives for sanding and trimming, such as files, knives, sandpaper, or rotary tools. However, you should be careful not to damage the part or expose the inner layers of the laminate.

2 Painting and coating

Another way to enhance the appearance and performance of LOM parts is painting and coating. This involves applying a layer of paint, varnish, lacquer, or other substance to the surface of the part, either by spraying, brushing, or dipping. Painting and coating can provide various benefits for LOM parts, such as adding color, gloss, texture, or patterns, as well as protecting them from moisture, UV rays, abrasion, or corrosion. You can choose from a wide range of paints and coatings, depending on the type and thickness of the laminate material, as well as the desired effect and durability.

3 Sealing and gluing

Sometimes, you may need to join or seal multiple LOM parts together to form a larger or more complex model. In that case, you can use sealing and gluing as a post-processing method. This involves applying a sealant or an adhesive to the edges or surfaces of the parts, and then clamping or pressing them together until they bond. Sealing and gluing can help to create a more seamless and stable structure, as well as to prevent delamination, warping, or cracking of the parts. You can use different types of sealants and adhesives, such as epoxy, silicone, polyurethane, or cyanoacrylate, depending on the strength and flexibility required.

4 Cutting and drilling

Another post-processing method that you can use for LOM parts is cutting and drilling. This involves creating holes, slots, notches, or other features on the part, using a cutting or drilling tool. Cutting and drilling can enable you to add functionality, compatibility, or customization to your LOM parts, such as attaching fasteners, connectors, or other components, or modifying the shape or size of the part. You can use various tools and techniques for cutting and drilling, such as saws, drills, punches, lasers, or water jets. However, you should be careful not to damage the part or cause delamination or deformation.

5 Finishing and polishing

The final post-processing method that you can use for LOM parts is finishing and polishing. This involves applying a final touch to the surface of the part, using a finishing or polishing tool or material. Finishing and polishing can improve the smoothness, shine, and quality of your LOM parts, as well as to remove any defects, scratches, or marks. You can use different methods and materials for finishing and polishing, such as buffing, waxing, rubbing, or polishing compounds. However, you should be gentle and avoid over-polishing or removing too much material.
