From requirement to a reviewed manufacturing route
Before a part runs, we assess the file or requirement against the way it will be made. The result is read by a person who runs these machines, then returned by email with the proposed route and any questions.
Guides and manufacturing routes
Use the review below for the complete sequence, or go straight to the reference that answers your question.
How we decide
Geometry validation, slicer intent, route selection, and the evidence retained with a decision.
File requirements
Formats, units, drawings, assemblies, and the context that makes a review useful.
Design guide
Walls, spans, holes, clearances, and features considered against the chosen nozzle.
FDM
Fused deposition modelling is Opus Aether Manufacturing’s primary process for functional parts and production work.
MSLA/LCD resin printing
MSLA/LCD resin printing is run in house for fine detail, smooth surfaces and small parts.
Five steps, one accountable handoff
Each decision is read before the next one begins.
01
Send a file or requirement
Send STEP, STL or 3MF, or describe the part in plain language. The useful context is what it joins, what it sees in service, and which features matter.
02
We review the part
We inspect the geometry, likely orientation, material fit and whether the part belongs inside the available envelope.
03
We confirm feasibility by email
You receive what we would make, what we would change, and the reason. A question or a risk is not buried in a generic quote.
04
We make it
The agreed file and route are prepared for manufacture. A revised file returns to review because it is a new manufacturing decision.
05
We ship
The part leaves only after the agreed review has become a real, documented build.
What we check, in order
The route follows the geometry, not a generic profile.
The sequence matters. A material recommendation is meaningless if the file is not a usable solid. A chosen orientation is not a promise if the part cannot fit. We establish each decision before moving to the next.
Geometry integrity
We look for a closed, interpretable part rather than a collection of accidental surfaces, inverted normals, self-intersections or scale ambiguity. If the geometry has no reliable inside and outside, it cannot support a reliable manufacturing decision.
Orientation and layer axis
We identify the loading direction, visible surfaces and fit-critical faces. FFF parts are strongest along the deposited roads and less resistant across their interfaces. Orientation is therefore a structural and visual decision, not a button in a slicer.
Walls and features against the chosen nozzle
A small feature is assessed against the nozzle intended for the job, not against a generic printer profile. We check walls, holes, gaps, bridges and the places where a support strategy would change the visible result.
Material against the declared service environment
Tell us what the part meets, carries and experiences. We use that context to make a material choice, rather than treating the material name as an aesthetic preference.
Envelope and segmentation
We compare the whole geometry with the available build envelope. A part beyond it is not automatically rejected, but segmenting changes seam placement, assembly and risk. That is discussed before manufacture.
What comes back to you
The email makes the proposed route and its risks legible.
The feasibility email is a decision record, not an automated acceptance. It identifies the received revision, the proposed material and orientation, the features that drove the decision, and what we would alter or need clarified before proceeding.
Where the file is ready, that email makes the next step unambiguous. Where it is not, it gives you a specific choice: revise the geometry, accept a stated trade-off, change the material or divide the part. It does not turn uncertainty into a silent default.
What we flag and what we warn about
A blocked decision and a visible risk are not the same thing.
Flagged
A flag blocks the decision until we have contacted you. It might be a non-manifold body, a wall that cannot be formed with the selected nozzle, unclear units, a fit-critical feature without its mating context, or a part outside the single-piece envelope. We do not print past a flag.
Warning
A warning does not necessarily stop the part, but it may affect its appearance, strength direction, assembly or service behaviour. It appears in the review so you can decide with us. A proposed setting change that may affect visible finish is surfaced as a quality risk, never applied quietly.
Ownership, intended use and the work we decline
We need enough context to decide whether the work belongs here.
We screen ownership and intended use during review. Send only files you are entitled to have made, and provide enough end-use context for an honest decision.
Start with the actual part
Send the file, or explain the requirement and the environment it must serve. We will read it before we make anything.
