Können Sie ein Ersatzteil ohne Zeichnung nachbauen?

Ja, das ist einer der häufigsten Anfragen bei uns. Aus einem beschädigten Originalteil, Fotos und den wichtigsten Maßen erstellen wir ein CAD-Modell und drucken danach eine Passprobe zur Kontrolle vor der Serienfertigung.

Wie schnell können Sie ein defektes Teil ersetzen?

Bei vorhandenen Daten liegt ein Muster meist in 2 bis 4 Werktagen vor. Wenn zunächst nachkonstruiert werden muss, kommt die Zeit für Vermessung und Modellierung dazu, üblicherweise ein bis zwei zusätzliche Tage.

Lohnt sich digitale Ersatzteilbevorratung?

Für Teile, die selten aber wiederkehrend gebraucht werden, ja. Statt physisches Lager vorzuhalten, speichern Sie das CAD-Modell und bestellen bei Bedarf die passende Stückzahl, ohne Lagerkosten für Jahre im Voraus.

Können gedruckte Teile Originalersatzteile vollwertig ersetzen?

Für viele Kunststoffkomponenten wie Abdeckungen, Griffe oder Halter ja, wenn Werkstoff und Belastung zusammenpassen. Für sicherheitsrelevante Bauteile oder solche mit engen behördlichen Vorgaben sollte die Eignung im Einzelfall geprüft werden.

3D printing for maintenance and spare parts

Rebuild obsolete or discontinued spare parts, replace broken plastic components and bridge delivery gaps. From a damaged sample or a few measurements we produce a ready to use part.

Spare part samples often ready in 2 to 4 working days

Typical maintenance cases

In maintenance speed matters most: a machine is down, a part is missing, and the original manufacturer no longer supplies it or needs weeks.

Obsolete spare parts remade

Plastic parts for machines the manufacturer no longer stocks, reconstructed from an original part or technical drawing.

Broken parts remade

Broken handles, covers and brackets, printed from the broken piece, often with small reinforcements at the failure point.

Protective covers and guards

Touch guards and cover panels for machines and equipment, matched to existing mounting points.

Bridging delivery gaps

Interim solutions when an original spare part is on order but the equipment must keep running until it arrives.

Suitable materials

For spare parts we choose material based on the original part's load, not on its original manufacturing process.

Details needed for spare part production

01The broken or worn original part, ideally as a sample, otherwise as a photo with scale and key dimensions.
02Known operating load: mechanical, thermal or chemical, so the replacement lasts at least as long as the original.
03How urgently the part is needed, so we can prioritize between a quick sample and a checked series run.
04Whether digital archiving of the model is wanted for future reorders.
05Quantity for the current repair and an estimate of future demand for the same machine.

Print spare parts instead of waiting on long deliveries

In maintenance, time to restart often determines the cost of downtime more than the price of a single spare part. When an original manufacturer no longer stocks a plastic part or lead times run into weeks, a short-term reprint is often the most practical solution, especially at small quantities where tooling investment does not pay off.

Reverse engineering from a broken part is routine work: from the broken original, supplemented with caliper measurements or a 3D scan, we build a CAD model that is often slightly reinforced at the failure point to address the original weak spot. Before producing a larger quantity we print a fit sample so dimensional accuracy is confirmed on site.

For parts needed repeatedly, digital spare part storage pays off: instead of financing physical stock for years, the CAD model stays archived and gets printed on demand in the required quantity. This lowers storage cost and makes even small runs for rare machine variants economical, which would otherwise not be stocked at all.

Spare parts FAQ

Can you rebuild a spare part without a drawing?: Yes, this is one of the most common requests we receive. From a damaged original part, photos and key dimensions we build a CAD model and print a fit sample for checking before series production.
How fast can you replace a broken part?: With existing data a sample is usually ready in 2 to 4 working days. If reverse engineering is needed first, add the time for measuring and modeling, typically one to two extra days.
Is digital spare part storage worthwhile?: For parts that are needed rarely but repeatedly, yes. Instead of holding physical stock, you store the CAD model and order the needed quantity on demand, without carrying storage costs for years in advance.
Can printed parts fully replace original spare parts?: For many plastic components such as covers, handles or brackets, yes, when material and load match. For safety relevant parts or ones with strict regulatory requirements, suitability should be checked case by case.
