3D printing is a manufacturing process that builds objects layer by layer from plastic filament. This method allows for custom shapes, rapid prototyping, and small-batch production, but it differs from injection-molded or industrially manufactured products. Surface finish, texture, and minor dimensional variation are normal characteristics of the process.
“3D printed parts are the same as factory-molded plastic.”
3D printed parts are produced differently and may not have the same surface finish, strength properties, or environmental resistance as injection-molded products.
“If it looks solid, it can handle heavy loads.”
3D printed items are not designed for structural, load-bearing, or safety-critical applications unless explicitly stated.
“All plastics behave the same.”
Different materials (PLA, PETG, ABS, TPU) have different heat resistance, flexibility, and durability characteristics.
Visible layer lines and slight surface texture
Minor variations between prints
Small dimensional tolerances due to the printing process
Strength and durability that depend on material choice and design
These characteristics are normal and do not indicate defects.
3D printing is ideal for:
Decorative items
Organizers and holders
Light functional components
Custom-fit parts for non-critical uses
Process Limitations
3D printing involves heat, cooling, and layering, which can result in:
Slight warping on large flat surfaces
Cosmetic variations
Differences in color between filament batches
These are part of the manufacturing process.
The materials listed below are commonly used in 3D printing and each has different characteristics that may affect appearance, flexibility, durability, and heat resistance. Material selection does not guarantee suitability for any specific use. Customers are responsible for ensuring the selected material is appropriate for their intended application. When needed, we can provide general guidance based on typical use conditions.
MATERIAL
GENERAL TRAITS
NOT SUITABLE FOR
PLA
Rigid, good surface detail, commonly used for decorative and light-use items
Outdoor exposure, high-heat areas, load-bearing parts, structural supports, automotive use, safety devices
PETG
Increased impact resistance compared to PLA; moderate flexibility
Structural load-bearing parts, safety-critical applications, medical use, high-impact mechanical systems
TPU
Flexible, rubber-like feel, used where bendability is desired
Structural support, rigid mechanical parts, safety restraints, high-friction drive components
ABS
More temperature resistant than PLA; slightly flexible and impact tolerant
Structural load-bearing applications, safety equipment, food-contact items unless certified, prolonged UV exposure
All printed items are intended for decorative or light functional use only. These materials are not engineered plastics and are not substitutes for professionally manufactured, certified, or safety-rated components.
My current printer is the Bambu Lab P1S 3D Printer with AMS, which allows me to print with multiple colors.
