Vextrix3D: FDM and SLA 3D printing with engineer review in Chelmsford

Vextrix3D is a 3D printing service based in Chelmsford, Essex (England), working with FDM and SLA technologies to produce functional prototypes, mechanical parts, miniatures, decorative models and custom projects. The company presents itself as a workshop that reviews every model before printing: it checks printability, orientation, wall thickness and material choice, and contacts the customer if it detects any issue before starting production.

Work process: from file to printed part

The flow begins with the customer uploading the model, who can send one or several parts in a single quote and indicate the intended use. An engineer then reviews the file and, if everything is correct, a clear quote is issued with the price and print parameters. Printing only starts once the customer approves the quote, with no obligation to proceed. Most orders are printed and shipped from the UK within 1 to 3 working days; larger or highly detailed models may take a little longer.

FDM and SLA: two complementary technologies

The company clearly distinguishes the use of each technology. FDM, which deposits molten filament layer by layer, is aimed at strong, functional parts, with a build volume of up to 256 × 256 × 256 mm, layer heights from 0.08 to 0.28 mm and a typical tolerance of ±0.2 mm depending on geometry. SLA, which cures liquid resin layer by layer using light, is used when fine detail and surface quality are paramount, with a volume of up to 223 × 126 × 230 mm, layer heights from 0.02 to 0.1 mm and an X/Y resolution of approximately 16.8 × 24.8 µm.

Available materials

The FDM catalogue includes eleven filaments: PLA (stable, for prototypes and decorative parts), PLA Matte (matte surface that hides layer lines), PLA Silk (glossy, for decorative and display models), PLA Tough+ (stronger and less brittle, for light functional prints), PETG (durable and versatile), PETG-CF (with carbon fibre, rigid and suitable for structural parts), TPU (flexible and durable), ABS (impact-resistant), ABS-GF (glass fibre reinforced), ASA-CF (with carbon fibre and UV resistance for outdoor applications) and PA (very tough nylon for gears and engineering parts). Heat resistance values are approximate and the colour is chosen when requesting the quote. Seven resins are offered in SLA.

Applications and types of parts

The workshop shows work grouped by categories: functional prototypes, decorative models, mechanical parts and artworks. The company states that it regularly prints functional prototypes and mechanical components, and that it optimises wall thickness, infill and orientation according to the real use of the part. It also offers high-resolution resin printing for miniatures and models where surface quality and fine details matter more than strength.

Indicative prices and quote

The site's pricing guide shows indicative examples: small parts from £4 in FDM and from £15 in SLA resin; medium parts usually between £10 and £35; and large parts or complex assemblies with individual quotes. The company warns that these amounts are only a reference and that every quote is reviewed before printing, as the final price depends on size, material, print time, supports, quantity and finishing.
