01 / Why choose this material
Properties and uses
of PMMA.
Transparent plastic for parts where clarity and visual appearance are paramount. It can be machined and polished to obtain high-quality optical surfaces.
PMMA, polymethyl methacrylate, or acrylic, is a transparent plastic used in display and lighting. Polishing improves clarity after machining; a matte finish can be useful when light diffusion is sought rather than transparency.

PMMA applications
Light diffusers
Diffusers and lighting parts according to texture and thickness.
Viewing windows
Windows to observe the interior of a prototype.
Aesthetic prototypes
Presentation parts where visual finish is paramount.
02 / A choice based on usage
Choose PMMA
based on your part.
These criteria help define the material, geometry, and working conditions before manufacturing.
01
Visualization
For windows and displays, visible face quality is key. Define areas requiring polishing.
02
Lighting
Surface texture, thickness, and geometry influence light diffusion. Validate the result with a prototype.
03
Impact and assembly
PMMA does not automatically replace PC for impact protection. Review loads and fixings.
The part's function is the starting point.
Indicate loads, temperature, environment, and appearance needed. If the drawing requires a specific grade, include it in the request.
03 / Finishing also counts
Finishes and appearance
of PMMA.
Define visible surfaces and the required result for your part. Requested treatments are included in the quote.
The part retains machining marks. Indicate adjustment surfaces and visible faces on the drawing.
The image could not be loaded. Try a different finish.
Reference images: material, geometry, and surface preparation influence the outcome. Special finishes are quoted upon request.
04 / From design to quote
CNC machining
of PMMA.
Milling and turning allow manufacturing PMMA parts from a block, plate, or bar. The tool removes material to obtain faces, cavities, drilled holes, and contours according to the design.
Send a 3D model per part in STEP or a native supported format: SLDPRT, X_T, X_B, IPT, CATPART, PRT, SAT, or 3DM. Attach a PDF drawing for threads, inserts, or specific tolerances. STL is accepted only for 3D printing.
Upload your file and request a quotePart tolerances
For dimensions without a specific tolerance, Proto&Go! applies ISO 2768-m. With a drawing, equivalent tolerances to IT11 can be assessed, depending on the geometry and requested dimensions. Attach the drawing and mark the functional surfaces.
Calculate a tolerance ↗Quantity and cost per part
In CNC, setup costs are distributed across the batch units. The final reduction depends on machining time and material.

Frequently asked questions
Before manufacturing
in PMMA.
Properties, applications, and manufacturing: answers to prepare your request.
What is PMMA and what properties does it have?
Transparent plastic for parts where clarity and visual appearance are paramount. It can be machined and polished to obtain high-quality optical surfaces. Avoid generalizations regarding chemical resistance or impact resistance: it depends on the agent and the grade. It does not automatically substitute a polycarbonate safety protection. The added values are references from the published PDF; the supply grade and testing can change them.
What parts can be manufactured in PMMA?
We can manufacture display stands, light diffusers, viewing windows, and aesthetic prototypes. CNC machining allows adapting the geometry to your 3D file. Define the loads, the environment, and the finish so we can review the application.
Are PMMA, methacrylate, and acrylic the same material?
PMMA is the abbreviation for polymethyl methacrylate, commonly known as methacrylate or acrylic. Specific properties depend on the grade and supply format. For machined parts, also specify the areas requiring optical finish.
Is it necessary to polish methacrylate after CNC machining?
If you need good transparency on machined surfaces, it is advisable to request transparent polishing. Machining leaves tool marks. You can also choose a matte sandblasted finish to diffuse light or paint on specific surfaces.
Is PMMA usually cheaper than polycarbonate to machine?
Not necessarily. In the Proto&Go! indicative comparison, PMMA is estimated to be more expensive than PC for the same part. The actual price depends on machining, polishing, geometry, and quantity; request both quotes if you want to compare them.
How much does it cost to machine a PMMA part?
The price of CNC machining PMMA depends on geometry, grade, tolerances, finish, and quantity. It includes material, preparation, and machining. Upload your 3D file to the Proto&Go! platform to receive a quote with cost and lead time.
What tolerances can I request for a PMMA part?
For dimensions without a specific tolerance, Proto&Go! applies ISO 2768-m. With a drawing, equivalent tolerances to IT11 can be assessed, depending on the geometry and requested dimensions. Attach the drawing and mark the functional surfaces.
What file do I need to manufacture a PMMA part?
Send a 3D model per part in STEP or a native supported format: SLDPRT, X_T, X_B, IPT, CATPART, PRT, SAT, or 3DM. Attach a PDF drawing for threads, inserts, or specific tolerances. STL is accepted only for 3D printing.
