Q

ASA poor coating adhesion

A

ASA can be coated but pretreatment is the key to success; mold release agent residue is the most common invisible killer; primer system matching is more important than topcoat adjustment.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent r...

Q

ASA shutdown cleaning contamination

A

ASA purging specifications are different: refuse foreign cleaning materials; emptying with its own material plus turning off heating is the standard action; contamination risk far outweighs the saved cleaning time.

Q

AEPDS extrusion

A

Stability is the quality foundation of AEPDS extrusion; parameters and cooling are both important; inspection ensures consistency.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

ABS annealing deformation recurrence

A

ABS annealing temperature and time must be sufficient, slow cooling sets the shape; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems later

Q

ABS stress cracking

A

Internal stress and media are the mechanism of ABS stress cracking; annealing is an effective countermeasure; assessment ensures application safety.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post ABS; stress cracking; internal stress; chemical media; annealing; assembly

Q

ABS surface hardness improvement

A

ABS fears scratching, choose among high-hardness grade, coating and composite; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems

Q

ABS 3D printing mainstream

A

ABS is the FDM classic, strong in both strength and post-processing; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems

Q

ABS FDM printing temperature

A

ABS printing 230-250°C with enclosed chamber to prevent warpage; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems

Q

ABS electroplating grade processing

A

The surface treatment of ABS electroplating grade is the quality key; process specifications ensure adhesion; testing verifies performance.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

Poor ABS painting/printing adhesion

A

90% of ABS poor adhesion is 'surface contamination': clean first before talking about paint; mold release agent is the number one suspect, lubricant precipitation is an invisible killer, and internal stress causes the coating to be cracked from the inside.
