Geometry and orientation
Wall thickness, overhangs, support, visible faces and interfaces affect orientation and preparation.
FDM manufacturing
FDM 3D Printing for Parts, Prototypes and Models
Choose a printing plan around what the part needs to do. We review geometry, material preference, quantity and finish before confirming the manufacturing scope.
What the review covers
Material and intended use
Material availability and suitability are reviewed against the stated job; no one material fits every requirement.
Finish and assembly
Visible layers, support marks, joining, inserts and post-processing should be included in the scope.
Information to send
- Current file version and units
- Intended use and any interfaces that matter
- Material preference or “recommend a material”
- Quantity, finish and colour preference
- Required date and delivery city
Questions buyers ask
Can you guarantee a universal tolerance?
No. Requirements are reviewed for the selected process, material and geometry.
Will the surface match injection moulding?
FDM has a visible layer structure. Any additional surface preparation must be agreed separately.
Can large parts be printed?
Large assemblies may need subdivision and joining. One-piece limits are confirmed from the selected equipment and orientation.
Geometry and print planning
The tray photograph shows thin walls and repeated compartments; the skeleton image shows flat interlocking pieces. For comparable geometry, identify which faces must remain clean, which connections must fit and whether pieces are printed separately. Orientation, support removal and layer direction belong in the manufacturing plan.
The photographs illustrate geometry; they do not establish a material grade, tolerance or functional test result. Prepare material and finish requirements.
Plan the details before printing
Planning a 3D Printed Electronics Enclosure Prototype
Plan board mounting, connector access, cable space and lid closure around the complete assembly, with a copyable enclosure brief.
Ordering a Small Batch: Approve the First Part Before Repeating It
Count parts and sets, define the first-part approval, control revisions and plan packing before repeating a prototype across a batch.
Large 3D Prints: Planning Splits, Joints and Assembly
Plan split lines, alignment, visible seams and packing before a large printed model becomes a collection of separate components.
What to specify for an FDM part
Mark the faces that will be visible, the interfaces that must fit and any thin or unsupported features. Ask the quotation to identify the selected material grade, orientation and support/finish scope. State quantity per unique part rather than only the number of assemblies.
A layer setting does not by itself guarantee overall accuracy. Define critical dimensions and the agreed inspection method for your actual part.
