A promise of high detail does not say which features will be visible at the intended distance or where support marks will remain. Assess a decorative resin model after the agreed finishing process, using a fixed viewing side, light and distance. This guide does not establish suitability for skin, medical or food contact.

Define the viewing condition and essential details
Record whether the model is for a cabinet, desk or photograph. Agree normal viewing distance and lighting. A scratch visible only under magnification may not be a rejection at one metre, but that criterion must be agreed beforehand.
Mark front, rear, side and top views and rank them by importance. The scale-model detail inventory helps decide which features matter at final size. Discuss support marks alongside finishing rather than assuming every face will look identical.
Measure meaningful and fragile details
Measure relief height, groove width, letter height and thin projections needed for recognition. Machine resolution or a datasheet does not prove that every feature will remain readable in every geometry. Mark fingers, antennae, railings and similar fragile parts, including handling and packing points. Ask about altered geometry or separate assembly if normal handling would threaten them.
Agree supports and final condition
Orientation and supports can leave marks. Identify acceptable locations and the face that should remain clear. Finishing may remove material or round edges, so account for dimension-critical details.
Assess the finished material state
Resin properties can change through washing and curing. The producer must follow the exact material process. Assess the agreed finished state, not an unfinished sample, and do not treat this guide as instructions for handling uncured resin.
A fixed visual assessment example
The fictional example is a miniature façade viewed from 50 cm under one agreed desk lamp. The front is the primary face, a 1.2 mm-high relief letter matters, a 0.8 mm roof edge is fragile and support marks may be acceptable at the rear. These are editorial inputs, not a tested model or process capability limit.
| Check | Criterion to observe | Possible decision |
|---|---|---|
| Letter | Recognisable at 50 cm without magnification | Accept or enlarge lettering |
| Support marks | Absent from front; rear matches agreed reference | Accept or revise orientation |
| Thin roof edge | Intact after agreed unpacking and placement | Revise packaging or geometry |
| Final condition | Washing and curing recorded by producer | Do not assess before finishing |
Separate a criterion from an observed result
Record the actual observation, photograph ID and decision after receiving a sample. A letter recognisable only in a macro photograph fails the selected viewing-distance criterion even if geometry is technically present.
Request an assessment of the visible result
Send a marked image showing the important lettering, thin areas and primary face to the 3D printing service, with final dimensions, viewing distance and finish. Ask whether an available production route can meet that visible purpose. This educational resin guide does not confirm resin production at OmniTechs.
If the process remains open, compare FDM, SLA and SLS against those requirements. A critical small detail may justify a representative trial before the full model. Assess it after finishing. Visual acceptance remains separate from strength, service life and contact suitability.
