Post-processing options
Post-processing should focus on appearance display, dimensional fitting, connection assembly, and testing verification. Parts involving assembly positions need to be reserved in advance for machining and coating allowance.
To support itRemove the printed support structure, focus on controlling the support contact points, and avoid cracking at edges caused by hard prying.
PolishingImproves support marks, layer lines, and edge feel, but will slightly alter local dimensions and the shape of sharp edges.
SandblastingAchieve a more uniform matte surface, suitable for engineering prototype display and slight surface mark reduction.
Spray paintEnhances color and appearance consistency, but will increase coating thickness, so assembly surfaces need to allow for clearance.
attacked YaSuitable for low-strength thread verification; the hole edge must ensure wall thickness; frequent disassembly or high-torque locking is not recommended.
Embedded nutsTo improve connection reliability, it is necessary to confirm the hole diameter, embedding depth, and surrounding material thickness in advance.
BondingSuitable for disassembly and splicing or partial fixing; high-temperature test parts must confirm the glue's temperature resistance rating.
AssemblyUsed to verify structural fit and installation paths; painting, sanding, and thermal deformation all affect the final fit.
Key control point
The edges crackedThe material is relatively rigid; when supporting and grinding, sharp sharp pry should be avoided, and thin walls, hole edges, and sharp angles should be carefully protected.
Assembly clearancePainting, sanding, and surface treatment will all change local dimensions; the positions for movable fits, snaps, and housing engagement should be reserved in advance.
Hole Position StrengthThe positions of tapping, embedded nuts, and locking screws should ensure sufficient wall thickness to avoid cracks or localized cracking during tightening.
Temperature resistance matchedFor parts used in high-temperature testing, glue, fillers, nuts, screws, and assemblies must also meet the corresponding test temperatures.
